I have a really bad pulsating coming from my pump. It literally shakes all the solution hose when the trigger is pressed. I have replaced all the check valves and all the seals in the pump. Hydramaster have been a great help but im at wits end now and think the pump is knackered. Hydramaster can get me a new pump but it has to come over from the states and I have two really really busy weeks coming up that I need finacially
Is there anywhere apart from hydramaster I can get the same pump or one simular. Ive been told that its not quite as simple as putting a different brand of pump in?
Any advice would be greatly appreciated

daft question.... you have got all the air out of the system, as it sounds like it needs bleeding, but expect HM would of advised you of this.

I have bled all the air out of the system and replaced everything HM have said. Ive gone thru everything to make sure no air is getting in. Im puzzled as to what to do

Would have expected HM to have a couple in stock Luc Good luck the exhaust raps making a big difference.

Maybe get appointment booked for Oxford service centre

They pretty good, and as they are primarily pressure washer agents, they have good knowledge on water pumps.

Or send HM. a short video, perhaps might give better idea of problem.

Threres no possibility of any debris in the solution water hose,or supply water hose leading to the Cat pump? causing the pulsing?

Check your QC

Or in Mr B case a float ball or demand pump

your pump is only as good as the sum of its parts - if it is the pump that is the problem and you have replaced or checked the seals and valves seats or springs then if it is the pump it can only be the manifold or the drive system or the plungers and they are usually pretty robust compared to the aforementioned bits which have a much shorter service life - comparatively! Most experienced pump engineers(!) should be able to at least rule out the pump from the equation that is causing the pulsation
