pump parts Coated Plungers & Extension Rods

Recommended for use in the pumping of amine, glycol, or other fluids requiring restricted lubrication, chrome oxide is applied by a special process which melts a solid rod of chrome oxide and deposits it at high speeds onto the base material. This results in a better bond between the coating and base material and greatly reduces the chance of flaking off in service.

The Hard-Co coating is a nickel chrome hardfacing alloy that is deposited on a base metal. This produces a non-porous coating which is very dense and corrosion resistant.

Hard-Co plungers are general service metal plungers used in the majority of cases where ceramic plungers are not desired. These plungers gives the best overall combination of corrosion and wear resistance of our metal coated plungers.
