Self-Priming Centrifugal Pumps use magnetic drive technology.

Press Release Summary:

Model SP10 and SP22 magnetic drive centrifugal pumps offer max flow rates of 12 and 45 m³/hr respectively and max discharge heads of 13 and 37 m. Units have lift capabilities up to 7.6 m and can prime 5.5 m in 90 sec. Offered in polypropylene and PVDF versions, max operating temperature is 82°C for polypropylene and 104°C for PVDF. Pumps can handle fluids with specific gravities up to 1.8, such as sulphuric acid and sodium and potassium hydroxide.

Original Press Release:

Self-Priming, Mag-Drive Pump Range Extended

The Finish Thompson SP series of magnetic drive, self-priming centrifugal pumps has been extended following the addition of two new models which results in a significantly increased performance envelope across the range. The SP10 and SP22 pumps provide maximum flow rates of 12 m³/hr and 45 m³/hr respectively and maximum discharge heads of 13 metres and 37 metres.

Available from MICHAEL SMITH ENGINEERS FTI SP pumps provide a fast, powerful, yet economical performance with optimum versatility and because of their innovative design and corrosion-resistant materials are able to withstand the rigours of the most challenging applications.

SP pumps combine deep lift capabilities (up to 7.6 metres) and fast priming (5.5 metres in 90 seconds) with the important 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 ideally suited to handling fluids with high specific gravities 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 82°C for the polypropylene version and 104°C 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 to most process systems resulting in reduced installation cost and time.

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.
