Catalogue description records
This is a tapered-type pony rod for piston pumps. The pony rod (intermediate rod) extends between the crosshead and the piston rod, passing through the oil-seal housing that separates the power end from the fluid end and transmitting the reciprocating motion of the drive train. It is an aftermarket replacement for Kerr KF275-400 and fits the KT-3400PT, T-35 and T-40 pumps. Unit weight is about 5 lb.
This is a complete reciprocating piston pump unit; the listed rating describes its published flow and pressure capacity.
