Catalogue description records

The KA285-400 Electroplated Cylinder Liner is an aftermarket replacement cylinder liner for the KA285-400 mud pump. In the fluid end of a triplex or duplex mud pump, the cylinder liner is the replaceable bore in which the piston reciprocates and is one of the primary wear surfaces, so it is a routine consumable. This liner is built with an electroplated working surface and is dimensioned to match the KA285-400 bore.
