Leak-free, mag-drive ULTRAChem pump range is extended

15 March 2015

The Finish Thompson ULTRAChem Series of ETFE lined centrifugal pumps has recently been extended with two new models which increase the maximum flow rates up to 160m3/h and maximum differential heads to 67m.

Engineered for extreme reliability ULTRAChem magnetic drive, sealless pumps are suitable for pumping hazardous, hard-to-handle chemicals in chemical processing, water treatment and other similar challenging applications.

Available from Michael Smith Engineers, these leak-free, magnetically driven pumps combine a tough ductile iron casing with a Tefzel (ETFE) lining to ensure outstanding corrosion resistance. They feature powerful neodymium magnets which drive the impeller through a carbon-filled PTFE lined barrier for dependable, leak-free operation with no environmental emissions, no double mechanical seal costs and no seal-support systems.

A two-piece dynamically balanced outer drive with multiple pole options matches drive to motor power for greater efficiency. This outer drive incorporates Finish Thompson’s 'Easy-set' mounting system so that the drive magnet can be fitted to the motor shaft without having to measure the magnet set-height and ensures a perfectly set magnet thereby removing a potential cause of misalignment and so improving reliability.

Other features include a Kevlar reinforced barrier which reduces the air gap between driven and driving magnet and so maximises magnetic power to transmission. Using Kevlar for the barrier reinforcement enables maximum working pressure to be increased to 20.7bar.
