Catalogue description records
This is a 4-inch vulcanized, high-temperature piston assembly for mud pumps. As a complete piston, it pairs the piston body with its bonded sealing rubber and reciprocates inside the cylinder liner to move the pumped fluid on every stroke. The vulcanized, high-temperature construction noted in its designation describes the sealing rubber; it is supplied as an aftermarket replacement part. Where the original wears, this assembly is intended to restore the seal against the liner bore.
A piston assembly is the complete piston — body and sealing rubber — that reciprocates in the liner to move the pumped fluid.
