Pressure washer pump spares and repair kits

Industrial plunger pumps are built to be rebuilt. Water seals, valves, ceramic pistons and oil seals all wear with use, and replacing them with the right kit brings a pump back to its rated flow and pressure for a fraction of the cost of a new pump.

Finding the right part

  • Check the identification plate on the pump for the brand, model and serial or code number.
  • Choose the brand above, then the pump series or kits and spares section.
  • Each pump page lists its matching valve, seal, piston and oil seal kits, and many link to the manufacturer's parts list.

If the plate is worn or missing, send us a photo of the pump and we will help identify it.

Brands we cover

Annovi Reverberi, CAT, Comet, Hawk, Interpump (including HYPACK hydraulically driven pumps), Neron, Pratissoli, Speck and Udor. We supply complete replacement pumps as well as spares.

For technical advice or help choosing a part, call 015395 66193 or email sales@flowjet.co.uk.
