Centrifugal pumps offer fast priming

SP centrifugal pumps are suited to handling fluids with specific gravities up to 1.8, such as sulphuric acid, phosphoric acid and sodium and potassium hydroxide.

The Finish Thompson SP series magnetic drive, self-priming centrifugal pumps are available through Michael Smith Engineers.

The SP series combine deep lift capabilities, up to 7.6m below the pump and ultra-fast priming, 4.0m in 90 seconds.

As a result of their superior lift and high working pressure capabilities, the SP series is suited to handling fluids with specific gravities up to 1.8, such as sulphuric acid, phosphoric acid and sodium and potassium hydroxide.

Reliability, low maintenance and safe operation are also assured thanks to the magnetic drive technology.

This eliminates the need for seals and removes the potential for leakage which can result when seals fail in other centrifugal pump designs.

SP series pumps also have the ability to run dry without damage.

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 82C for the polypropylene version and 104C for the PVDF version.

SP series pumps are capable of delivering flows up to 22m3/h and differential heads to 22m and can operate on systems with operating pressures up to 6.2bar.

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.
