Catalogue description records
This Spray-welded Alloy Plunger is an aftermarket replacement part for reciprocating (plunger-type) mud pumps. A plunger is the polished reciprocating element of the fluid end; the high-pressure seal is formed by stationary packing around the plunger rather than by a seal on the plunger itself. This plunger features a spray-welded alloy working surface. It is supplied to match the form and fit of the original component; any reference shown is used for identification only and does not imply original-equipment manufacture.
