Product Description

Gas-powered pressure washer

Italian-made PA unloader valve
Premium Unloader Bypass Assembly (optional)

All Canpump triplex plunger pumps feature a modular design with a detachable unloader valve that can be replaced or upgraded. Some pump models come pre-fitted with a premium Italian-made external unloader bypass valve by PA S.p.A.

  • Additional length of the external bypass hose allows water to cool down to an extent compared to built-in unloaders.
  • Delays overheating, extending the amount of time you can run a pressure washer in bypass mode without spraying.
  • Can be replaced easily.

will need mods to fit honda 390 ps4240h
i bought it several months ago and just got to installing . the only problem for a lot of honda 390 or maybe the chineese 420 is the in and out water goes out to the right , not like the AAA junk that was on ti and wouldn't it figure that it goes EXACTLY where the right handle mounts as you can see in the picture , so i just put right side handle behind where it would have mounted , wallered out the holes in handle frame to 3/8 and put a bolt thru it withe washers and a nylon nut . problem solved

5.0 out of 5 stars Easy to install and came pre-loaded with pump oil!
Reviewed in the United States on January 13, 2023
Replaced my old water pressure pump from my Honda GX340 pressure washer. They both had a 1” shaft diameter which is an important bit of info to know when changing out your pump. The only inconvenience was that the unloader valve came separate so that had to be installed. No biggie. I’ll update if anything changes but so far so good, gave it a test run today and works great.

Reviewed in the United States on November 30, 2023
Finally got around to using this setup. 16hp engine & this pump. With green nozzle it makez 2700psi regulator turned all the way up. With my 20" surface cleaner it makes 2900psi. Absolutely worthless. Do not waste your money. I'm past the return date. So just money lost. Reached out to customer service. They blame it on the wrong tips. Tried with all tips I have. Pump will not make over 3k psi tried 3 different green tips 3 yellow tips, and 2red including what came in it..
