Balanced-Pressure Proportioning Pump Skids

An alternative to bladder tanks, CHEMGUARD injection-type balanced-pressure proportioning pump skids automatically proportion foam concentrate over a wide range of flows and pressures without manual adjustment. Frequently used for fire protection in large aircraft maintenance facilities and large flammable liquid storage facilities, these completely self-contained foam systems are installed adjacent to atmospheric foam concentrate storage tanks.

A complete balanced-pressure proportioning system – control valves, proportioning controllers, duplex gage, positive displacement foam pumps (electric, diesel, water turbine, or gasoline motors), and all interconnecting piping – is mounted on a pump skid (structural steel base) for stability. Multiple proportioning units can be assembled in a single system, and flow ranges can vary according to job requirements. CHEMGUARD balanced-pressure proportioning pump skids are compatible with all foam concentrates.
