This complete pump repair kit helps simplify service or rebuilds by replacing common wear components and restoring a reliable seal to help prevent leaks in HVAC/hydronic hot and chilled water circulation applications.

Three kits available

Same kit, same fit — the difference is the seal material inside. Choose your build from the dropdown above.

• Standard – Carbon/Ceramic/Nitrile — ordinary hot water and chilled water systems

• Upgrade – Carbon/Ceramic/Viton — hotter systems, glycol and chemicals

• Upgrade – Silicon Carbide/Viton — gritty water and hard-wearing duty

What’s included:

• Gasket set

• Oil plug washer

• Shaft sleeve

• Sleeve gasket

• Stainless bushing / spacer

• Bushing gasket

Which kit do I need?

Most HVAC and hydronic circulation systems take the Standard Kit. Step up to an Upgrade Kit if your system runs hotter, carries glycol or chemicals, or handles gritty water.
