NOV Mono offers a comprehensive portfolio of products for all types of sewage, water and raw material handling applications, and examples will be on display in stand 216 in Hall A6.

The exhibition will also be the first time NOV Mono displays standard and custom Chemineer™ fluid agitation equipment, following its acquisition of Robbins and Myers and its associated businesses in 2013.

Underlining Mono’s dominance in providing progressing cavity pumps, grinders and associated equipment to the waste water industry, will be a working dosing pump model. This newly launched dosing pump from Mono™ provides a reliable and low maintenance solution for applications requiring a controllable, low flow, dosing action. The pumps have a smooth, non-pulsing action and are ideal for either intermittent or continuous dosing duties in high pressure, low flow applications. This makes them a cost-effective and practical alternative to expensive gear pumps - with minimum wearing parts, they offer an extended working life.

Mono’s revolutionary EZstrip™ transfer pump is also on display, representing the biggest leap forward in progressing cavity pump design for 30 years. The EZstrip can be 'Maintained-in-Place' using only spanners and a hex key It can be disassembled, de-ragged and maintained without disconnecting suction or discharge pipework. This reduces a typical day-long maintenance operation to just a 30-minute job and dramatically cuts maintenance costs. To underline the EZstrip pump’s ease of maintenance, visitors to the Mono stand will have the opportunity to win an iPad by disassembling the pump against the clock!

A working EZstrip™ CT201 Muncher, a recent addition to the EZstrip™ product family, will allow visitors to see the macerating capabilities of the Muncher product. Easy to install, the CT201 Muncher features various cutter stack size options which help create the optimum particle size for each process requirement to protect downstream equipment from blockages. A quick-release inspection cover allows the cutters to be replaced with the unit in-situ, therefore reducing maintenance time and costs. The unit’s high torque performance cuts operating power requirements, while the low cutter tip speeds significantly reduce wear rates and noise vibration.

Recognising the need to maximise plant uptime, Mono will also promote its high quality Universal Parts. Engineered and manufactured by Mono, these parts can be fitted to many other brands of progressing cavity (PC) pumps, thus offering a reliable and alternative solution to help reduce equipment downtime.

Mono’s expertise in sewage and wastewater applications will be reinforced by their Chemineer™ products, a recognized global leader in standard and custom fluid agitation equipment and systems. Mono’s Chemineer industry specialists will be on hand to explain the benefits of such products as the compact Kenics™ UltraTab™ static mixer, which delivers a high degree of mixing in turbulent flow applications. Designed to provide complete blending within short downstream distances, the UltraTab also creates a low pressure drop through the mixing element to boost the overall energy efficiency of the process. Its integral wall injector upstream of the mixing element forces flow stream additives through the high energy dissipation region to ensure reliable mixing efficiency.

Alongside this will be the Chemineer model 20 HT/GT mixer, fitted with an RL-3 Ragless impeller to create the ideal wastewater plant mixer. The model 20’s high-efficiency gearbox and the RL-3’s unique design (which prevents fibrous material build-up) combine to minimize downtime and maintenance costs, increase performance and extend service life. The modular design of the model 20 HT/GT mixers helps reduce customer spares inventories, while their variable speed capability improves process control. The RL-3 impeller can be easily retrofitted into existing applications and provides safe and reliable operation. Together they are ideal for wastewater applications where blending operations involve suspended solids and fibrous material, and they help eliminate the performance deterioration and increase energy usage and gearbox damage which can otherwise happen.

NOV Mono played host to an important visitor when His Royal Highness, Prince Richard, Duke of Gloucester, visited the company’s headquarters in Manchester recently. During a visit to the northwest he included a stop at Mono’s Audenshaw plant to find out more about the tremendous success which the company has been enjoying in recent years, and their plans to relocate to a larger site in Chadderton.

Following a presentation by Mono’s Managing Director for Industrial Products, Steve Valentine, the royal visitor toured the company’s manufacturing and pump assembly operations.

“The Duke has a keen interest in British manufacturing so it was a good opportunity to show him the great progress we have been making in recent times.” says Steve Valentine. “NOV Mono is now the world’s leading producer of progressing cavity pumps, and with our associated products such as grinders and mixers, there was plenty to show.

The Duke was interested to hear that we’re a great example of a very successful global company, with our products being sold all around the world, and into many different markets from wastewater treatment to chemicals, oil and gas and food processing.”

During his visit, the Duke met a number of long serving Mono employees including Skilled Machinists Kevin Hill (46 years’ service) and Dave Crabtree (45 years’ service) plus Credit Controller Sue Lawton (40 years’ service). The Duke also met Commercial Apprentice Rachel Hall, Craft Apprentice Joel Barden and Technical Apprentice Ryan Fitzpatrick. He was accompanied on his visit by the Mayor of Tameside, Councillor Joe Kitchen and his consort, Shirley Kitchen.

The new Mono dosing pump provides a smooth pumping action with no pulsation and very low shear. The pump is ideal for either intermittent or continuous dosing duties in high pressure, low flow applications, and represents a cost-effective and reliable alternative to the more expensive gear pumps traditionally used for these types of duties.

The new dosing pump offers many advantages, not least of which is the option to transfer low flows at high pressure (up to 72 bar/1044 psi). With no valve components (reducing the number of wearing parts), blockages are eliminated and the working pump life is extended. Stators are available in a variety of different materials, and their flexible and resilient operating characteristics enable the pump to handle a wide variety of applications, and again, increase the pump’s resistance to wear. When maintenance is required, it can be completed without the need for any specialist skills, thereby maximising uptime.

Manufactured to ISO 9001:2008 quality assurance standards, the modular design of the new dosing pump allows the four models in the range to cover performance requirements from 25 litres per hour (0.11 USGPM) and 72 bar pressure (1044 psi), up to 1,250 litres per hour (5.5 USGPM) and 12 bar pressure (174 psi). All the pump components, with the exception of the body, coupling rod and suction chamber are supplied in stainless steel as standard, and have the option for internal pump components to be supplied in Hastelloy, which allows the pumps to be used in severe chemical environments. Other optional features include a range of fixed or variable speed drives with mechanical variable speed or frequency inverter.

“This pump builds on the success that our Compact C range has enjoyed to date,” says Mono’s European Sales Manager, Mr Ian Horton. “The pump also shares a number of components with the small Compact C pumps, which reduces the need for stockholding and provides extra flexibility for interchangeability of parts. Together with high reliability and low maintenance requirements, the new dosing pump delivers many benefits for dosing or metering applications.”

The Southern Water plant in Peacehaven features a number of different Mono™ pumps, including EZstrip™ cake pumps, LF injection pumps and Widethroat pumps.

The new Peacehaven plant uses 11 kilometers of newly constructed tunnels to bring sewage flows into two new pumping stations and transfer the treated sewage to a new outfall which has been constructed in nearby Friar’s Bay. “That creates a significant need for reliable and effective pumping solutions that will keep the plant operating efficiently at all times,” says Mono Account Manager Mike Burton.

Mono worked with two of the sewage processing equipment providers involved in the project, the Andritz Group and Saxlund International, to offer the most efficient pumping solutions. “For Andritz, who supplied the plant’s centrifuge equipment, we provided a variety of pumps which are now being used for different duties,” continues Mike. “These include transferring imported sludge cake, dosing dewatered sludge cake and barrier layer injection where lubricant is added to the pipework to ensure that the sewage moves smoothly through the system. Each of these is a key application in its own right, so reliable operation is absolutely crucial.”

Mono provided a similarly diverse package of pumps for Saxlund International who supplied the drying and digester process equipment for the plant, “These are now being used for cake blending, drier feed, cake transfer and polymer dosing applications,“ adds Mike. “This project certainly demonstrates Mono’s ability to provide a comprehensive package of pumps for large scale projects such as this one. The specific pumping requirements at the plant vary quite significantly from duty to duty, ranging from sludge transfer through to lubrication and dosing, yet the extensive range of products that we offer meant that we were able to meet all those requirements with ease.”

Many of the Mono pumps provided for Peacehaven feature the company’s innovative EZstrip technology. The EZstrip range of products has rapidly become accepted in the waste water sector as a practical and highly effective way of reducing maintenance costs and improving uptime. The EZstrip design allows the cake pump to be dismantled simply by removing a few screws, and without disconnecting or removing any pipework. This gives immediate access to the rotating parts so that blockages can be removed quickly and easily and can reduce the time taken to remove a full drive train, including rotor, stator and screw conveyor from a full day, down to just 8 minutes.

“The EZstrip technology on the Mono pumps allows them to be maintained in place and that certainly offers attractive savings in terms of maintenance times and costs,“ adds Matt Drew, Sales Manager for Saxlund. “Having such a wide variety of pumps supplied by a single manufacturer was also an attractive proposition as it helped ensure compatibility between various parts of the process.”

The completed Peacehaven waste water treatment works is covered by an 18,000m² grass roof – the largest green roof of its kind in the UK and handles the 95 million litres of wastewater which is generated each day by towns of Peacehaven, Brighton and Hove, Telscombe, Saltdean, Woodingdean and Rottingdean.

In 1935, Mono made its home in Audenshaw and has enjoyed a very successful 79 years at this facility. The success that the business has seen over those years and the recent explosion of demand for our products and services mean we have now, quite simply, outgrown this much loved home. It is therefore with a great deal of excitement that we are delighted to announce our complete relocation to a far bigger base just a few miles north of this existing site.

Our new facility is more than 3 times the size of our existing site and will provide us with the space to meet increased demands on capacity, whilst enabling us to continue to deliver world-class products and services. The product development opportunities that we will be focusing on over the next year are innovative and truly exciting – its step change time for Mono!

The first areas to move over to the new facility will be our warehousing, assembly and despatch, which are currently scheduled to commence relocation from late summer (August/September) 2014. Whilst we are hoping that there will be minimal business disruption during this period, we are currently building up core product inventory to ease the production transition as we start to relocate our manufacturing business.

Evidently, it’s only fair that we make you aware of the relocation plan and to provide an opportunity to build up your own stock levels prior to us moving, so that you can place any additional orders should you wish to do so.

In addition, we wanted to take this opportunity to make you aware of some changes which you will start to see in relation to our NOV divisional name and branding. As part of an NOV restructure, Mono now forms part of Industrial Products and Solutions within a new division of National Oilwell Varco which is called NOV Process and Flow Technologies. The branding changes will be transitional but will be starting with immediate effect – so you will be seeing slightly different e-mail signatures and business cards. Over the course of time, more and more branding will change, so, as a matter of courtesy, we wanted to make you aware. We will be retaining our Mono brand, but wanted to ensure you understood the references to NOV Process and Flow Technologies (as opposed to NOV Mono).

If you have any questions or concerns, please do not hesitate to contact a member of the sales and marketing team.

A leading UK supplier of dipping plant and ancillary equipment to the world’s latex, nitrile and PVC industries has underlined their confidence in NOV Mono by ordering four Epsilon high pressure progressing cavity pumps. The pumps have been fitted to the balloon-making equipment manufactured by Greenbrook Automations of Chesterfield, and have helped to transform the company’s reputation with its customers.

“We had previously been using another brand of progressing cavity pump on our equipment but they were proving to be inferior,” says Managing Director Robin Gronbach. “Customers were complaining that the pumps were suffering failures and that was beginning to affect our reputation as a manufacturer, so we had to make a change.”

The pumps fitted to the balloon-making equipment were handling highly abrasive, fine powder slurry, made of ground-up sedimentary rock known as Diatomaceous earth. Greenbrook required new pumps they could rely on to handle such a demanding application. “We had some experience of Mono™ equipment and knew that the company had a good reputation,” continues Robin. “When we investigated further we found that the Mono pumps were very competitively priced, but were also a lot better in terms of quality.

“We made the decision to go with Mono and it was definitely the right one. The pumps are powerful, rugged and reliable. We have been 100% happy with the Mono pumps, and the difference they made was immediately noticeable. We’ve had no failures at all and no other problems either since switching to Mono. We supplied the Mono-equipped balloon making equipment to a customer in Peru and they’ve reported that it has actually helped speed up their production process.”

The Epsilon pumps are designed to deliver outstanding performance, low whole-life costs and reduced spares requirements. Their gentle pumping action and low running speeds are ideal for highly abrasive applications such as this, and they can be installed vertically or horizontally for increased versatility. They feature a compact bloc construction and Mono's unique Flexishaft™ drive shaft connection, which eliminates wearing components and has a 10-year warranty for continued peace of mind.

“The Mono equipment has made an enormous difference both to us and our customers,” concludes Robin. “Not only have the pumps performed perfectly, but the service that Mono has provided has also been excellent and we’ll definitely be looking for more Mono equipment in future.”

Following the announcement that Mono is relocating to a new facility, which is more than 3 times the size of our existing site, we are happy to confirm that the relocation process has now started!

The project centers on an EZstrip progressing cavity pump which is now being used on sewage transfer duties to ensure that the plant can guarantee the quality of the treated sewage under any flow conditions.

Powered by a 4kW motor and operating at a duty speed of 226 rpm, the EZstrip pump draws sewage from the centre of the final settlement tank at Dwr Cymru’s Crymych treatment plant. It pumps the sewage back up to the head of the treatment system, from where it returns back through the filter bed to the final tank. This ensures that the plant’s biological filters do not dry out and remain effective even in very low flow conditions. This in turn helps to maintain the quality of the final sewage within the required boundaries, at all times.

Dwr Cymru approached NOV Mono because of its ability to provide a full turnkey package which covered all the stages, from initial site survey, design and manufacture, through to full mechanical and electrical installation. “Mono did an excellent job on this project,” says Steve Hewett from Dwr Cymru’s Capital Delivery team.

“Initially we had worked out a specification for the recirculating system ourselves. When Mono completed the same exercise, they arrived at the same conclusion which was extremely reassuring. They then worked with our civil contractor and managed every aspect. Mono installed the pump, suction pipe, rising main, control panel, overpressure and high temperature devices and completed the final testing and commissioning. From our point-of-view, that made the whole process completely pain-free.”

Steve was also impressed with the actual quality of the work. “Not only did Mono handle both the electrical and mechanical sides of the work, but they completed everything to a very high standard too. We’ve since completed a very similar project with Mono at our Lamphey treatment plant and again the results were excellent.”

The progressing cavity pump at the centre of the Crymych project features Mono’s revolutionary EZstrip design which allows it to be maintained-in-place. This provides a quick and easy way to disassemble, de-rag and maintain the pump without the need to disconnect suction and discharge pipework.

Three TR Munchers and three Compact C range pumps from NOV Mono have been chosen for a demanding sewage handling operation in the Caspian Sea. They will be used to macerate and pump black water on a deep-water semi-submersible drilling rig which is located there.

The Mono™ equipment has been selected by Wärtsilä Water Systems Ltd of Poole, which provides products and solutions for offshore facilities used in oil and gas exploration, development, and production, as well as marine vessels. “The equipment we provide for a project such as this will have to withstand some extremely harsh offshore conditions and comply with environmental legislation. So we need pumps and macerators that we can rely on” comments Wärtsilä’s Projects Manager, Jeremy Freeman. “We know Mono’s equipment very well, and we would always consider it for a project of this kind.

“We also receive very proactive support from Mono, and this was another factor in our decision. Rather then just supplying pumps they look carefully at each specific application and suggest the most appropriate solution that will deliver the performance that’s required.”

The Mono TR Munchers will be used to macerate the black and grey water produced on the platform at a capacity of 8.8m3/h. They are designed specifically for the efficient maceration of abrasive sludges, and are very effective in capturing irregular shaped objects, thanks to their layback cutter shafts which are set at an angle to the incoming flow. The shafts operate at different speeds to tear apart any solids, while a cantilever shaft design reduces the number of wearing components by eliminating the need for bottom bearings and seals.

The Muncher also features Mono’s EZstrip™ technology which allows the unit to be maintained in place, thus drastically reducing the maintenance time required and maximizing availability. Any rejected objects are allowed to fall into an easy-access waste trap which is set below the cutter stacks to prevent damage. Munchers can be supplied to comply with the ATEX Directive 94/9/EC for this type of hazardous area application.

The three Mono Compact C Range progressing cavity pumps, which operate with a Wärtsilä Water Systems Ltd membrane bioreactor, provide a fluid transfer solution that will fit into the compact space of the platform yet still perform reliably and efficiently at 2 bar pressure. Available in cast iron or stainless steel, and with a choice of rotor and stator materials for different applications, these high pressure pumps eliminate the need for a series of pumps when pumping over long distances or with high head requirements.

They offer a suction lift capability of over 8 metres, and in addition to applications such as this one, their positive displacement, progressing cavity action also makes the C Range pumps ideal for accurate process control and variable speed dosing duties. As with the TR Muncher, the Compact C Range pumps can be supplied to comply with the ATEX Directive 94/9/EC.

Mono has recently increased the strength of its offering to the global oil and gas industry by establishing a specialist Oil and Gas office in Southampton, UK. The team which operates from this base provides dedicated industry expertise and support for customers in many different areas of the global oil and gas sector.

A single TR Muncher from Mono has been selected for a sludge grinding application, which was previously performed by 3 grinders, supplied by another manufacturer. The 3 grinders were struggling to deliver the required performance and maintenance levels at a large waste water treatment plant in Rhode Island, New England.

The CT203 Muncher installed in the Field Point plant’s Gravity Thickening Building is already delivering many benefits, including increased efficiency, simpler operating procedures and reduced maintenance requirements. “It has certainly simplified the operations at the plant,” says Bob Mack, of New England Environmental Equipment who installed the Muncher. “Having only one grinder and being able to repair it in-house, rather than shipping it offsite, reduces the maintenance time and helps keep the plant up and running.”

The Field Point plant processes up to 150 million gallons of waste water per day in dry weather, and more during rainy periods, so any equipment installed there must offer outstanding levels of reliability and performance. Designed specifically for the efficient maceration of abrasive sludges, the Mono Muncher is a twin shaft, slow speed, high torque grinder that macerate the solids within a flow, and it has been used successfully in a wide variety of waste water and industrial applications.

The twin shafts feature a series of interleaving cutters and spacers which create a 'positive displacement' grinding action, with the differential cutter speeds pulling apart any fibrous material, cropping and shearing plastic items into small pieces and crushing any brittle material. A cantilever shaft design removes the need for bottom bearings and seals and so significantly reduces the number of wearing components, while the pull-back cutter stack allows removal without disturbing the pipeline.

A patented built-in trash trap set below the cutter stacks catches any rejected material and so prevents damage to the cutters, while clean-out ports allow the rejected object to be removed easily. The Muncher can be used for a wide variety of pump protection and other industrial duties, and the range includes pipeline or channel models, with optional high-flow side rails to increase capacity.

NOV Mono has designed and manufactured its largest W Range progressing cavity pumps ever built. The four pumps have been ordered for two major wastewater treatment plant upgrade projects, and at 11-metres long they will have double the size and double the capacity of pumps normally used for this type of sludge cake application.

The pumps will be used in a duty/standby configuration on a Cake Reception and Buffer Silo unit. This unit will house 4 feeder channels to transfer sludge cake from the silos into the specially-designed, 4-metre long hoppers of the W Range pumps. Injection points have been included in the hoppers so that additional material can be blended in to create the required degree of dry solids sludge. The W Range pumps, which also feature dry-run and over-pressure protection devices, will transfer the sludge to a pre-thermal hydrolysis process at a rate of 60.5m3/h.

“We worked extremely closely with the client to create the pumps which would handle the huge capacity which the customer required,” says Mono’s Senior Applications Engineer, Paul James. “They were tailored to meet the customer specific requirements and include features such as specially-designed blending points, and a variable pitch auger which will ensure a consistent sludge transfer without any imbalances in the feed stream.”

The pumps were also designed to be supplied in 3 parts to provide ease of installation and maintenance, as the pumps are situated in a chamber beneath the silo. Each part has its own lifting point, together with a single lifting point for when the pump is fully assembled.

Mono’s EZstrip‘maintain-in-place’ technology will allow the pumps to have a retractable feed chamber which can be disconnected by removing only a few screws, thus giving quick and easy access to the pin joint area for removal of any blockages or compressed cake. This significantly reduces the time needed to strip and rebuild the pumps - usually without the need to disconnect or remove any pipe work - and so generates significant increases in availability, plus savings on maintenance costs.
