General Pump Kit 28HP is a high-pressure packing kit for General Pump triplex plunger pumps with 20mm plungers. Packings are the seals that surround each plunger and keep high-pressure water inside the pump. The “HP” version is built for pumps running at the higher end of their pressure range, where standard packings can wear faster or extrude under load.
Worn packings typically show up as water dripping from under the pump head, a gradual loss of pressure, or a pulsing, uneven spray. Replacing them restores full pressure and stops leaks. It also protects the plungers and manifold from damage caused by running on failed seals.

- High-pressure packing kit for 20mm plungers
