Self priming mag drive pump range from Michael Smith Engineers
The Finish Thompson SP series of magnetic drive, self priming centrifugal pumps has been extended to include two new models, the SP10 and SP22. The pumps are said to provide maximum flow rates of 12 and 45m<sup>3</sup>/hr respectively and maximum discharge heads of 13 and 37m.
Available from Michael Smith Engineers, the pumps are said to provide a fast, powerful, yet economical performance with optimum versatility. In addition, their corrosion resistant materials are said to be able to withstand the rigours of the most challenging applications.
The SP pumps combine deep lift capabilities (up to 7.6m) and fast priming (5.5m in 90s), 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 lift and high working pressure capabilities, the company claims they are ideally suited to handling fluids with high specific gravities up to 1.8, such as sulphuric acid, phosphoric acid and sodium and potassium hydroxide. The SP Series magnetic drive technology is said to ensure a reliable and safe operation.
The pumps can be mounted to most standard motors and are available in a choice of Polypropylene or PVDF. Maximum operating temperatures are 82°C for the polypropylene version and 104°C for the PVDF version.
Typical applications 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.
