Sotera Diaphragm Pumps

The power distribution is a unique reciprocating, spring driven, double diaphragm configuration retaining constant pressure, regardless of the load. Motor amperage is actually reduced as back pressure increases. No Internal Bypass required - the pump automatically goes neutral when the end of hose valve is shut off. These pumps can be configured in materials that are resistant to industrial chemicals and proven to provide complete compatibility coverage for a wide range of fluids.

1/2" Air Operated Diaphragm Pumps

The SP100 Series Air-Operated Double Diaphragm Pump can be configured in materials that are resistant to industrial chemicals and proven to provide complete compatibility coverage for a wide range of fluids. With the highest flow rate in the industry and the lowest pulsation, you can quickly and efficiently transfer fluid without the splash and mess. Patented Air Valve design provides the low pulsation (low pressure drop) and the patented ring construction provides the lowest turnaround time in maintenance. You can clean the check valves quickly with the threaded rings, no nuts or bolts to lose. With its extensive list of features, the SP100 Series outperforms the competition time and time again.

1" Air Operated Diaphragm Pumps

The SP100 Series Air-Operated Double Diaphragm Pump is truly unique in its design and construction. The patented ceramic air valve results in amazingly fast valve shift for a 66% reduction in pulsation. This reduces splash back and provides consistently even laminar flow. Over-molded stainless steel rings on all threaded manifold connections prevent over-tightening and potential splitting of the manifolds. he unique diaphragms were designed and constructed for consistent performance and a longer operating life. Industry standard foot mount configuration makes it easy to retrofit onto most existing mounting plates.

The SP100 can be configured in materials that are resistant to industrial chemicals making it compatible for a wide range of fluids. This high efficiency pump boasts highest flow rate in the industry at 56 GPM (211 LPM) at 20% less air consumption reducing your operating costs. The threaded ring makes maintenance easy saving time and money in this area as well. With its extensive list of features, the SP100 Series outperforms the competition time and time again.
