ProMinent® Sigma/1 Explosion-Proof: Metering Pump for Explosion-Proof Applications
Safe for Hazardous Metering
The choice for simple metering in hazardous applications. The ProMinent® Sigma/1 Explosion-Proof motorized pump may be operated manually by adjusting the stroke length knob (displacement per stroke) at a constant stroke frequency using a constant or variable speed motor. Automatic control of displacement per stroke via analog (4-20mA) signal is possible with optional motorized stroke positioning systems (Also Explosion-Proof).
The ProMinent® Sigma/1 is a mechanicallyactuated diaphragm metering pump capable of flow rates to 38 gph (144 L/h) and pressures up to 174 PSI (12 bar).
