Today, we give you even more information on PD pump rotor clearances. Below is an easy to use chart that provides the rotor clearance data for the Waukesha Cherry-Burrell Universal 1, 2, & 3 positive displacement pumps.

These tables will help you to determine the proper back face, rotor to body, and front face clearances. Please note that the assembly clearances stated in these tables are for reference only. Actual pump clearances may vary based on pump performance testing.

For non-standard rotors, or if the process uses special clearance rotors, please contact a Holland Sales Engineer with the serial number of the pump.

The above information was taken from the Waukesha Universal 1, 2, 3 Maintenance Manuals.
