The PowerStar 4 Pump

Notes:
Most air compressors will produce 4 to 5 SCFM of compressed air per horsepower at 100 psi.

All air-driven pumps will operate on low air volumes as long as the supply of air is sufficient to overcome minor internal leakage and operate the air selector valve.

Performance charts are based upon air supply pumping potable water with flooded suction.

Pump Performance
Solid lines indicate approximate flows at various driving air pressures. Dotted lines indicate air consumption.
Examples:

Operation
In operation, the P45 pump using 100 psi of input air pressure could produce a maximum liquid output of 520 psi; 80 psi air - 416 psi output; 60 psi air - 312 psi output; and 40 psi air - 208 psi output. Output pressures will vary and be reduced by 5 to 10% through internal friction depending on the lubricity of the liquid.


By regulating the incoming air supply at the pressure regulator, the liquid output can be infinitely adjusted through the pump's pressure range.
