Sotera Systems SP100 Series air-operated double diaphragm pump

Hurll Nu-Way is offering the SP100 Series air-operated double diaphragm pump, which is manufactured by Tuthill Corporation under the brand name Sotera Systems.

The pump includes the patented QuikSeal threaded ring construction. The threaded ring is designed for quick-turn access to clear ball checks and replace diaphragms. This eliminates the need for multiple fasteners (bolts) on the manifolds and fluid caps, reducing parts and complexity.

This can reduce ‘pinch points’ on the diaphragm to extend its life and, according to the company, can reduce maintenance time by up to 50%.

The patented QuickFlow air valve design includes a non-centring ceramic air valve with a fast tripover, which is claimed to result in a 67% reduction in pulsation, delivering up to 17.5 gpm for the 0.5″ model and 57 gpm for the 1″ model. In some applications, pulse dampeners can be eliminated, making the pumping system less complex. In addition, the company claims the pump offers a 20% improvement in air efficiency compared to other pumps.

The pump can be configured in materials compatible with a range of chemicals to make it suitable for a range of applications.
