REPLACEMENT PARTS

Replacement parts for the KT Series version pumps used with standard hydrocarbon vacuum pump oil are shown on the following 

pages.  Some parts such as pistons and cams may be used in several models of pump, and individual item numbers may have a 

description which includes other model numbers.

Many pumps are ordered and equipped with special modifications and accessories, or adaptations for special fluids. Therefore 

when ordering spare parts the pump model and nameplate serial number must always be provided to insure verification and 

shipment of the correct parts.
