Catalogue description records
This is a 3.75" plunger for the Kerr T-50 (T50) pump. The plunger is the polished reciprocating element in the fluid end; the high-pressure seal is made by stationary packing around the plunger rather than by a seal on the plunger itself. It weighs about 23 lb. This is an aftermarket replacement part offered as a reference equivalent to Kerr part number KA-63-375DW, not an original Kerr component.
