Wider range of magnetic-drive, self-priming centrifugal pumps
Available from Michael Smith Engineers, the Finish Thompson SP series of magnetic-drive, self-priming centrifugal pumps has been extended with two new models that increase the performance envelope across the range. The SP10 and SP22 pumps provide maximum flow rates of 12m3/hr and 45m3/hr, respectively, and maximum discharge heads of 13m and 37m.
FTI SP pumps provide fast, powerful, yet economical performance, with excellent versatility; and because of their innovative design and corrosion-resistant materials, they withstand the rigours of challenging applications.
SP pumps combine deep lift capabilities (up to 7.6m) and fast priming (5.5m in 90 seconds) with the advantages of magnetic drive technology, such as no seals to replace, no leaks and the capability to run-dry without damage.
As well as their superior lift and high working pressure capabilities, they are suited to handling fluids with high specific gravities of up to 1.8, such as sulphuric acid, phosphoric acid and sodium and potassium hydroxide. Reliable, low-maintenance and safe operation is also assured thanks to the SP Series magnetic drive technology.
The pumps are available in a choice of polypropylene or PVDF, which results in a tough and durable, corrosion-resistant pump. Maximum operating temperatures are 82degC for the polypropylene version and 104degC for the PVDF version.
SP Series pumps can be mounted to most standard motors, while NPT or BSP threads, adjustable flanges or union connections make it easy to connect the pumps to most process systems, resulting in reduced installation costs and time.
Typical applications for the magnetic-drive, self-priming centrifugal pumps include sump emptying, transferring from underground storage tanks and tanker trucks, pumping in systems that are liable to have trapped or entrained air, or in process systems where run-dry protection is needed.
