Pump Customization

Many performance upgrades are offered for Tri-Clover® Pumps:

  • Oil Bath Conversion – Convert pump bearing housing to oil lube, instead of grease lube. This improves bearing life, which provides better pump wear and improved reliability.
  • ZMT Seal Conversion – Convert pump seals to the flushless, a more rugged ZMT engineered seal.
  • Wearbility Upgrade – Convert pump to a hardened body with a hardened impeller for up to 4 times better life.
