This is a clamp that joins the pony rod to the piston rod in Kerr reciprocating pumps, fitting the KM-3250PT, KMX-3300SHPT and T30M models. It sits in the rod train between the power end and the fluid end, where the pony rod extends from the crosshead to the piston rod that drives each pumping stroke. It is offered as an aftermarket replacement part that interchanges with Kerr part number KM-280. Approximate weight is about 2.40 lb.
A piston rod connects the crosshead in the power end to the piston in the fluid end, transmitting the reciprocating motion that drives each pumping stroke.
