Sotera SP100 Series air-operated double diaphragm pump

The SP100 Series air-operated double diaphragm pump, by Tuthill Corporation under the brand name Sotera Systems, incorporates several key features unique to this pumping principle. The first is the QuikSeal threaded ring construction. The threaded ring is designed for quick-turn access to clear ball checks and replace diaphragms. This design eliminates the need for multiple fasteners (bolts) on the manifolds and fluid caps reducing parts and complexity. It has the added benefit of reducing maintenance time by up to 50%. This design also reduces ‘pinch points’ on the diaphragm resulting in longer diaphragm life.

The second is the patented, QuickFlow air valve design. This non-centring ceramic air valve features a fast tripover, resulting in a 67% reduction in pulsation, as well as a high and smooth flow - up to 17.5 gpm for the ½″ model; 57 gpm for the 1″ model. In many applications pulse dampeners can be eliminated, making the pumping system less complex and saving money.

The third benefit is a claimed 20% improvement in air efficiency compared to competitive pumps. Less air consumption saves money over the long run.

SP100 can be configured in materials compatible with a wide range of chemicals.
