COVID-19: Pump and Filtration Business Continuity

To keep our staff and clients safe, we made the decision to close our office on 23rd March 2020, with staff working from home where possible and minimising contact for staff who need to be at the office/works.

We currently have staff on hand to deal with deliveries and enquiries during normal office hours.

Our focus is to progress your matters efficiently and maintain a high level of client service.

Please be reassured that we are doing everything we can to complete your orders and enquiries.

Non-metallic pumps withstand a wide range of severe service applications

Spotlight on Plastics 

Non-metallic pumps withstand a wide range of severe service applications A recent research program conducted jointly by Pollution Engineering magazine and the customer service division of Vanton Pump & Equipment Corporation queried pump specifiers for the factors contributing to their selection of non-metallic pumps.

 Although many advantages of non-metallic pumps were indicated, corrosion resistance was clearly the number one factor – receiving 58% of the responses. This chemical inertness permits the safe application of a single pump for the complete pH range from 1-14 as well as for salts, halogens, solvents and other troublesome chemicals. Abrasion resistance, particularly when coupled with resistance to corrosion, was also frequently cited as grounds for selecting a non-metallic pump. 

Lower maintenance, longer service life, prevention of metallic contamination, lighter weight, and lower cost when related to high alloy and exotic metal pumps were also mentioned. 

When specifying a non-metallic material for the wet-end of the pump or other fluid contact components, and following factors should be considered: 

1. specific chemical(s) to be pumped and the possible range of process fluids 

2. degree of abrasiveness 

3. temperature range 

4. pH range 

5. importance of metal contamination avoidance 

6. field experience with similar installations

Critical selection factors for thermoplastic pumps

Non-metallics offer broad abrasion and superior corrosion resistance Although the use of thermoplastic pumps has become so common that some designs are now being carried on the shelves in distribution stocks, for those applications involving highly corrosive or abrasive fluids, selection of the right pump and the materials of construction should be made with care.

Despite the fact that individual thermoplastics can tolerate a broader range of corrosive and abrasive conditions than metals, misapplication is certainly the major reason for pump failure. The primary limitation on the use of thermoplastics is temperature.

The Plastic Alternative

While chemical inertness is the major reason for specifying a plastic pump, users can take advantage of other benefits as well

Not so long ago system designers would consider the use of plastic pumps only if available metal pumps were completely unsuitable. Plant engineers had learned to live with costly downtime and excessive maintenance due to corrosion. Extensive research activities concentrated on published corrosion rates for a long list of metals and exotic alloys in an endless array of chemical solutions at varying temperatures. Specific metal selection for a given application was left to the user's discretion, based on what were considered to be "allowable" rates of attack.

How to select a non-metallic pump

Pumps constructed of various non-metallic materials are widely used in wastewater and other pollution control applications. The use of non-metallic pumps for applications involving water and wastewater treatment, pollution control and other related services has been expanding at a dramatic rate for a variety of reasons. 

Some of these reasons are related to the growing awareness of the need to protect our environment and natural resources. Others are mandated by government regulations. 

Still others are associated with the development of new and superior engineered plastics and the corresponding economic need to extend equipment life and improve performance.

Wastewater - Application Possibilities Grow for Plastic Pumps

GROUNDWATER TREATMENT No matter what design solutions engineers and construction contractors devise to contend with the growing number of water and air pollution regulations, they can't do very much without pumps. Gravity sometimes may play a role in water and wastewater systems but pumps are, without a doubt, the prime movers in the business of fluid handling. And as water pollution control technology continues to develop to meet the needs, it is becoming more evident that non-metallic pumps are particularly suitable for many applications in the field.

How to Specify Nonmetallic Sealless Pumps for Transferring Acidic, Caustic, Abrasive and Toxic Solutions

Ever tightening regulations and heightened environmental responsibility have driven industrial and municipal facilities to rethink leak prevention, particularly when handling acidic, caustic and abrasive solutions that cause packing and mechanical seals to fail, and toxic solutions that demand failsafe containment. To transfer these solutions, operations and engineering management is relying increasingly on sealless, non-metallic pumps. Given the variety of types offered, recent advances in pump design and the myriad of fluid-contact materials available, this article attempts to update specifiers with guidelines needed to select the optimum sealless pump according to individual application parameters.

Pharmaceuticals - Plastic pumps - Cost vs Performance

Fluoropolymers are available that can outperform PVDF in temperature resistance, such as perfluoroalkoxy (PFA) resin, which can be used at operating temperatures to 500°F (260°C). But these formulations are expensive and usually exceed the needs of a pharmaceutical plant.

Pharmaceuticals - Plastic or stainless steel pumps - which is better?

If you've ever opened a tap at home to find that the water coming out had a brown colour, then you know part of the problem — rust from the iron in your pipes. While this is bothersome at home, it is unacceptable at a pharmaceutical plant, particularly in a purified-water line.
