A Better, Faster Way to Source Pumps

PFA Lined Gear Pumps Ideal for Aggressive and High Purity Liquids

Contributed by: PumpScout Staff

Michael Smith Engineers, a specialist pump distributor to the chemical, processing, and manufacturing industries, has presented the new PFA lined magnetic drive gear pumps to customers throughout the United Kingdom. The new pumps can be used for the accurate and reliable pumping of challenging liquids that include hydrochloric acid, ferric chloride, sulfuric acid, hydrofluoric acid, sodium hypochlorite, nitric acid, sodium hydroxide, and chromic acid.

The PFA lined gear pumps from Michael Smith Engineers feature non-metallic wetted parts and zero leakage, which offer safer pumping capabilities. The lined gear pumps are available in seven different sizes that include both DIN and ANSI flanged connections. No matter which size you choose, they all provide flows of 47 lit/min at differential pressures of up to 7 bar. They are also able to operate at temperatures up to 90 degrees Celsius.

There are numerous advantages to the PFA lined stainless steel housing that is used with these pumps. The pumps do not suffer from wicking problems that are most often associated with fiber reinforced housings. The effects of heat entrapment and thermal expansion are minimized. The effects of fluid absorption are also minimized, while the stainless steel housing increases strength and durability, which is required for all process pump applications.

Not only do the Liquiflo PFA lined stainless steel pumps offer corrosion resistance, they also provide smooth, pulseless flows, which makes them easy to monitor and control. In addition, they have an accurate output to within plus or minus two percent. The pumps are specially designed for easy servicing, so the downtime needed for routine maintenance is minimal.

The Liquiflo Polygard PFA lined pumps have demonstrated their durability in many applications that include pumping hot hydrochloric acid into a chemical reactor, injecting ferric chloride into a waste water treatment process, and circulating a hot mixture of solvents and hydrochloric acid for a specialty chemical manufacturer.
