Products 1 — 24 · Shop our wide selection of pumps for pressure washers when you need a replacement. If your pressure washer pump broke down or is too old,. If the pressure washer turns on, but it doesn't pressurize the water, don't leave it yet - the pump may have broken down. Professional pressure washers will have triplex or belt drive pumps, and entry-level gas pressure washers will have axial pumps.
If you've invested in a professional gas pressure washer with an axial cam or triple plunger pump, replacing the pump can be much cheaper than having to replace the entire pressure washer.
