Traditional elastomers including Nitrile [NBR], Ethylene Propylene [EPDM] and Viton/Fluorocarbon [FKM] are all used successfully in today’s progressing cavity pumps. Selection of the correct elastomer is just one aspect of ensuring reliable service, and good performance. Nitrile is a good all round elastomer for various chemical and slurry applications, and tends to be the first choice for abrasive duties. Viton has excellent chemical resistance properties, but performance is reduced if the liquid contains abrasive particles.

When selecting a pump, fundamental consideration should always be given to rotational pump speed [rubbing velocity is the term used to describe oscillation - in the form of a sine wave - of the pump rotor with the stator], differential pressure and the number of pump stages [‘slip’ or ‘backflow’ over the seal line of contact points between rotor and stator increases with pressure and can cause wear]. The more the elastomeric stator can flex when sharp abrasive particles pass over it, the less wear occurs. The ability of the stator to flex is significantly enhanced with Polyurethane, and tests carried out have given some very positive results.

Torqueflow-Sydex are now able to offer this excellent elastomer in virtually all of its pump range, giving enhanced reliability, service life and most importantly of all reduced running costs for its customers.

Polyurethane was first developed in the late 1930s as a replacement for rubber. This new organic polymer was an ideal substitute for scarce materials, and spurred numerous applications. Polyurethane coatings were soon used for the impregnation of paper, high-gloss airplane finishes and chemical and corrosion resistant coatings to protect metal, wood and masonry.

Formulations, additives and processing techniques continued to be developed and improved, and now polyurethanes can be found virtually everywhere in everyday life. Polyurethane elastomers are incorporated in a multitude of diverse products such as thermoplastic polyurethane, cast elastomers and Reaction Injection Molded (RIM) products.

Torqueflow-Sydex have signed an agreement to exclusively represent Franklin Miller Inc.’s range of solids handling equipment in UK and Ireland.

Franklin Miller grinders effectively reduce solids such as rags, plastics and wood that might otherwise damage valuable pumping equipment. The Taskmaster® is provided with cutter cartridge technology, unique to Franklin Miller, wherein 6 cutter disks and 6 spacer disks are replaced by one piece elements for far greater strength. Through using fewer components, the need for stack tightening is eliminated. As the teeth wear on other grinders the stack will gradually loosen and eventually fail, resulting in expensive repairs and down-time. This will not happen with the Taskmaster® cutter cartridge design. The Taskmaster® is available as an in-channel or in-line unit.

The Super Shredder® in-line disintegrator reduces tough solids entrained in pipeline systems. The unit combines world-class size reduction capabilities with a streamlined easy to maintain design that features only a few working elements. The Super Shredder® is ideal for applications requiring a heavy–duty, size reduction processor that can handle high flows with minimal head-loss. The unit utilises a low-speed, high-torque drive to chop, grind and shred solids into fine particles that can be easily processed by down-stream equipment. Its innovative open-centre spherical rotor design maintains a high percentage of open area, making this unit practically invisible to the flow. Size for size it can handle higher flows than other in-line grinder units.

The Spiralift® range includes the Spiralift® SC screenings conditioner that, grinds, washes, compacts and de-waters screenings with optimal washing capacity. The SC conditioning system can be placed in tight waste water treatment plant locations. The unit takes raw screenings from the screen and conditions them to minimise water, odour and organic material.
As the screenings drop into the SC hopper, they are washed by the upper spray nozzles and then ground by the Taskmaster® grinder. Next the Spiralift® wash-press intensively washes organics and flushes them back into the system. The remaining screening are then de-watered in the unit’s press zone. The processed screenings then pass through a discharge pipe, and are deposited into a bin, bag, hopper or conveyor all washed, ground and reduced in weight. The integration of the grinder and press technology combined with highly rugged construction make the Spiralift® SC unique and highly effective

The Spiralift® SL screening system is a fine auger screening system that grinds, washes, de-waters and conveyors non-organic material out of the liquid channel. The SL employs a shaftless auger screw and fine perforated screen that captures debris. By combining this ‘auger screen’ with the Tankmaster® Titan grinder, the system achieves its unique level of reliability and effectiveness.
First, the grinder reduces the solids to a small size and loosens up any trapped organics. A spray wash system then washes the organics off the solids and back into the flow where they can continue into the treatment works. This also significantly reduces the odour of the screenings. The perforated screen is wiped by the brushes around the perimeter of the auger. The brushes are highly durable and are critical to the reliability of the system. The homogeneously ground solids are effectively conveyed up the auger and can be easily disposed of, whilst free water flows back into the flow. As the unit operates at low rotational speed, it consumes very little power.

Factory achieves ISO9001 TUV Quality Assurance:

We are pleased to announce that effective 15th May 2007, our factory in Lonigo is now certified by TUV to ISO9001:2000. Today’s customers demand their suppliers meet t he latest international standard for quality management and quality assurance systems..

ISO 9001:2000 includes the following main sections:

• Quality Management System
• Management Responsibility
• Resource Management
• Product Realisation
• Measurement Analysis and Improvement

Sydex srl and Torqueflow-Sydex Limited are dedicated to providing the highest quality products and services that constantly meet or exceed customer expectations. The company’s philosophy is that quality assurance commences with the design of the product, and ends only when the customer obtains acceptable product function, perceived value and service.

All personnel within the organisation will assume accountability for the quality within their area of responsibility, and recognises the company values of total quality management. Through the effective instigation and integration of the quality system the company will address all aspects of customer satisfaction and will ensure that through continuous improvement prevent nonconformity.

The benefits of implementing ISO9001:2000 Quality Management System include:

• Policies and objectives set by 'top management'
• Understanding customer's requirements with a view to achieving customer satisfaction 
• Improved internal and external communications
• Greater understanding of the organization's processes
• Understanding how statutory and regulatory requirements impact on the organization and your customers
• Clear responsibilities and authorities agreed for all staff

• Lime of milk
• Chemical make up, etc.

The vertical agitator series gives an answer to your needs for fluid mixing in civil or industrial processes for water treatment.

Torqueflow-Sydex Limited

Building on the continuing success of Sydex Pump, Torqueflow-Sydex Limited has been created to bring a much needed, and long overdue fresh dimension to the pump market.

We will do this by providing high-quality products, delivered on-time at competitive prices coupled with exceptional expertise.

We have over 20 years experience in the pump market, and our knowledge tells us that customers need and want to work in partnership with their suppliers. One of our strengths is our flexible approach, enabling us to adapt and change according to our customers’ needs, providing them with best practice solutions for their pumping application.

Keeping running costs low are today more important than ever.
