Advanced Materials Extend Pump Uptime


Extreme-duty pump plungers, packing, & valves

CoorsTek Ceramic Plungers

Ceramic plungers work exceptionally well for most saltwater, chemical, and metering applications. CoorsTek specially-formulated grades of ceramic allow a standard 8 RMS surface finish — dramatically extending packing life.

With a durable stainless-steel core, CoorsTek plungers exhibit extreme corrosion resistance.

Ceramic plungers are available in hollow ceramic or solid ceramic designs.

When corrosion and abrasion resistance are required and extended packing life is needed, ceramic plungers are unequaled in performance. Contact one of our specialists for specific application information.

Ceramic, coated, and solid METAL plungers


Ceramic-coated pump plunger

Coated Plungers & Extension Rods
Coated components are general service coated plungers and extension rods used in the majority of cases where a combination of corrosion and wear resistance is needed. 

  • Standard base material: carbon steel
  • Optional base material: stainless steel


Tungsten Carbide Plungers
Ideal for most power oil applications and other areas with considerable wear and abrasion, this premium alloy coating offers superior wear resistance and longer life.

  • Standard base material: carbon steel
  • Optional base material: stainless steel


Chrome Oxide Plungers
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 chrome oxide and deposits it at high speeds onto the base material. This results in an excellent bond between the coating and base material.

  • Standard base material: Stainless Steel

Packing and valve expendables


Plunger packing

Packing & Valve Expendables

General service 838 plunger packing is composed of nitrile rubber and synthetic fabric and is recommended for service in fresh water, saltwater, propane, butane, gasoline, light or heavy oils, mild chemicals and acids, and most hydraulic fluid applications.

Optional packing materials — Additional sizes and materials including style 225 PTFE (polytetrafluoroethylene), assorted Kevlar® fibers, spring-load packing, and split-ring, die-formed sets are available upon request.
