Preventive Maintenance

Refer to section entitled Overhaul for the procedures necessary to perform maintenance.

Performance Chart

A pump’s ability to deliver material is based on the pressure (psi/bar) and quantity 

(cfm/lpm) of air supplied to the motor and the amount of material discharge [back] pressure to 
be overcome within the system.

This chart contains curves based on three different air pressures. The curves relate delivery 

in gallons (liters) per minute (X axis) to air consumption in cubic feet (liters) per minute 
(right Y axis) and to material discharge pressure in psi/bar (left Y axis).
