Anyone know a decent supplier for what i think is an unloader valve?

[reb78]

I have a big pressure/steam cleaner. Electric motor, diesel burner. Its old and needs some careful maintenance.

Its leaking slightly from the pin in the top of the part pictured above - i think its the unloader valve? I cant get the pin out to see if i can reseal it - should i be able to? If its non-serviceable does any one know of a decent supplier for these parts? Will a hydraulics place sell them?

Pressure washer spec and pics of part in question attached

yep dual pumps there called they have a catalogue . tel 01664567226https://www.dualpumps.co.uk/

Thanks. Thats dead handy.

It looks like the pin mechanism should drop out from underneath looking at the ones on their web page. I wonder if its worth dismantling to see if a simple o ring will fix it?

I always use this place

http://www.malcleanse.co.uk/

they've always been good with me, talked to them on the phone a few times when I wasn't sure what I needed and they were very knowledgeable

ordered something online once and they phoned me before posting it to make sure I'd ordered the right bit because it was an unusual valve

:-)

Worth taking it apart and looking mate

It could be a nrv letting by too not sure by looking at those pics

It’s either a k3 or k5 unloader valve both are flow sensitive. Yes comes apart from the bottom, not sure about a seal near the top as don’t usually bother taking customer units apart but as it’s your own wouldn’t hurt. Need to check motor current if replacing with a new unit as sometimes it’s easy to overload the motor.


Usually marked in the area circled with either k3 or k5 but difficult to see as may be motor side

If this machine has no output and hasn’t been used recently check that the pressure nozzle isn’t blocked or restricted as that can affect performance

if you're servicing it... a new set of valves for the pump doesn't cost much... £20 ish I think... it should run like new with a new set of valves in :-)

Thanks for all the tips so far. The leak (weep) is slight but its coming up and leaking from the holes in the adjuster screw at the top of the unloader hence wondering if theres a seal in there.

Are there any nasty suprises if i take the mechanism out?

Other than that it seems to be working well now.

As I said before I don’t usually take these apart but slackening and removing the larger fitting with both male and female threads also removes the complete valve from the brass casing. All springs etc are held in place with a small e clip on the central shaft. Have seen these working with more that a slight leak

It needs a strip and a good clean...water is getting past the bottom valve and seat and up inside the spring body. if that's a Cat pump or Interpump then take out the 6 valves and cages and give them a good clean too (20 min job) but you better have a good fitting socket and breaker bar as the big brass caps can become very very tight with age...And yes as long as they are not damaged then you can re-use the O rings

Thanks! I tried to undo those caps the other day. My god they're tight! I gave up rather than break it!

I think its a cleanwell 1500 but i dont know if thats a badge added by a seller/distributor.

With the brass caps, theres a set on the side and a set on the top. Which should i undo?

just looked at the pics...you have an Interpump fitted,very good pumps. undo the top and bottom valves but be very clean in your procedure as the smallest bit of grit will un-seat the valve plates..i normaly find those hot washers in scrap yards with burnt out boiler tubes and turn them into very good and strong cold washers..

My boiler tube has seen better days. But it still works and heats well. Are they hard to replace? Its great having the heat option.

there pretty much standard on a lot of powerwashers I have a Wesley Richards hot water power washer fitted with one https://www.dualpumps.co.uk/groups/INTPW__Interpump_Pressure_Washer_Pumps

you can buy them but very rarely fix them as they end up as thin as a cigarette paper

yea they are...i have a washer that has the pump with 9 lives fitted

you can buy new burner coils but cost big £££££££

 

[reb78]

Just looked at the prices! I only paid £200 for the whole unit!
