The PowerStar 4 pumps develop high output pressures by applying the principle of differential areas. The pump has a large area air piston (air driven at low 10-100 psi pressures). This air piston drives a small area liquid piston that pumps liquids to high pressures.
The liquid output pressure is determined by the ratio between the area of the air drive piston, the area of the liquid drive piston and the applied driving air pressure. The relationship of the area of the air piston to the liquid piston is referred to as the pump ratio which is indicated in the number following the air module number (P4).
Example: The P45 pump has a nominal ratio of 5 to 1 or 5 psi liquid pressure to each 1 psi of operating air pressure.
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 he 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.
