Did you mention the motor to him? hopefully his tech will test it out....

Terry - this is Jase, i spoke to you on the phone about a month ago about these problems as i had also sufferred from a leaking pumptec head and was pulling my hair out

Mine continued to leak after i spoke to you, but is now hopefully sorted - i think you have the same problem.

Basically, the pumptec pumps are top quality, they dont just leak after a few weeks for no reason. I explored all the normal routes as you did with just temporary bouts of fixing the leak and then having drips again a few weeks later. I knew something else in the set up was causing this, i couldnt just get unlucky with so many heads/kits leaking.

What happened with mine was the regulator which adjusts the pressure of the pump (on mine its a big brass bolt that screws in and out to adjust and is located on the out hose from the pumphead) wasnt working properly - it was slightly seized. I could still adjust pressure, and i was still getting backflow to the clean tank fine, but the seizing was still enough to mean there was too much pressure building in the pump head. After a few weeks, this would just cause enough pressure to unseat one of the Orings in the head and cause it to leak. I greased the regulator piston and found i could sense the flow had improved, so i then opened up the pump head and found that one Oring had unseated. I then opened up the other pump head i had and found the same Oring unseated.

I placed the Oring back, got a regulator kit to replace the plunger and seal in that and all has been good since - better flow, pressure AND NO LEAKS.

I hope that makes sense - basically i think you need to get the regulator on the Ninja checked/replaced as i would bet my last quid you are getting the same as i was - too much pressure build up in the pump head pushing a seal out of place and causing a leak shortly after.

Its not your pump mate, dont keep getting new heads/pump head seals, it wont work

^^  Good shout!

Prochem recommend lubricating the o-ring on the regulator every 50 hours but that’s on a TM or more on porty methinks


Terry

As you are in to burning rubber you must have some lubricant to try out before parting with more hard earned cash

Mr B

Just thought of it orifice = magnet if it is (blue tack, oxford) never panic Mr Mainwaring Mr LPG is more local

[Terry_Burrows]

  so funny new look yes I done all what you said to no avail you think ashby would know what to do,dont you! even today Derek claims of great pump heads er 400psi ones : but really 6 times since August 2011 , wtf
is really going on, I know its not me Derek likes to push the blame on everyone but his machines,I have the full back up of trading standerds on this case! I just want the machine to work I told Derek today I love me ninja please
sort it out

[CleanerCarpets]

Terry, you need to take a breather mate and read my post, i am telling you new information which will solve your problem, i never knew about the regulator seizing when i spoke to you on the phone, this is all new.

I agree, Ashbys have let you down, they should be checking whats causing the leak, not simply replacing the after affect.

Get them to check the regulator, stop getting so wound up about it mate and find out whats going on fella or you will never solve this. Dont get angry, get sorted

[dave123]

I think NLC could well be right about this that was the reason the pump on my ninja leaked . The regulator was jammed causing the psi to zoom up to 600psi .hope you get it sorted Terry .

[Terry_Burrows]

not being funny but you think Ashby should know there stuff without me saying someone off cleanitup says :
I dont mean that in a funny way,if they cant sort this out,this has been the same prob since August last year,
I say no more but Derek is quick to blame me,as if I dont know what I am doing,I laughed in his face sorry,but dont F'@@@ insult me in that way! is what I said, so lets see what they come up with now,this machine is less than 2 years old and done hardly much work its mint condition,in out! I like Derek but 6 times back come on! :

and £500 later! who is the mug!

[Tony Gill Carpet Smart]

Come on Terry you have had some real good advice why not use it thats what this forum is really good for .Wether or not you are fedup with it all it's got to be worth following up if it solves your proble

Tony

[Terry_Burrows]

Hi Tony I do   agree! but!there problem there machine ,my ferking money that gets wasted!
I only operate it not repair it, I think you love Derek or a soft spot : when your not in my situation
everyone is full of answers, good sound advice I must admit really and very much think the feedback is great!

when your parting with your money its not so funny...

[Len Gribble]

Terry

There is a company I know of when you take/send the machine to them the regulator is done as a matter course. Really cant comment on Ashby’s only had one service done by them that was years ago it passed the pat test other than that £160quid

Don’t think of you being a mug, gullible possible but more in line of a masochist (of the emotionally abused type and nothing to do with rubber)

[Terry_Burrows]

  yes I agree! scott and sons at st Albans I have spoke with them and they said I sholud not be having
this prob,as this machine  has got history with Ashbys,its not as if I took it elsewhere first as I have know them for many years,but do now feel some what let down as to why they are having probs solveing there very own machine,
after 6 goes at it I really think the machine is great thats why I am trying so hard to stay with it,only so
much you can take though I am starting to think theres not a single carpet machine on the market today,
thats trouble free,brand new or otherwise I have had quite a few : when your buying top end of the market
you just want reliability thats it :

[John Milnes]

Terry,
I got rid of a Ninja 400 psi nearly 3 years ago because I was having the same problems.

As my previous post on this, I called Pumptec in the US.....they said:
The motor is underpowered and is not mached to the head.

The issue I was having is that the bearings were wearing out on the motor; therefore causing the motor spidle to run out of true with the drive bearing and the result was premature wear on the seals.

heres an example:
I was pretty p1ssed off with repalcing pump head seals.....the motor had stopped and the pump was leaking....including the motor was corroded due to the leak.
Replaced with new head seals and new motor....not cheap! 3 months later motor had again stopped and pump leaking (remember everything is brand new).

This time I put new seals in the head and put new capacitor on the motor. I think one of the issues is that the capacitor breaks down after a while. MACHINE SOLD due to not being able to bear the continual costs of repairs.

Another example:
Then purchased a 600 psi Airflex...same head different motor ie 1/2 horsepower (much much bigger).
3 years later....zero motor problems (Cleansmart says they have not had one motor back for repair in this time).
This machine is running most days of the week. Every 6 to 8 months I will need to replace the piston and seals and offset drive bearing, just par for the course.

So there it is. Pumptec say the design is at fault and the same head running with a different motor has no issues.

[Terry_Burrows]

  wow thanks for that one! :

[CleanerCarpets]

terry isnt having problems with the motor - it isnt blowing seals after months, its blowing seal after hours

i agree that motor is under powered but terry has got a pressure problem, but hey ho - if he wants to live with it and not listen then thats up to him!!! keep getting new heads mate and moaning about Ashby's eh!!

pumptec heads are quality, they dont leak for no reason and replacing them isnt solving the problem when they keep blowing every few hours/weeks

[Kinver_Clean]

The pump head may have a certain pressure rating on it. This is the max operating pressure for sustained running. If the outlet is blocked or the regulator is not working the pressure will build up until either the motor stops through sheer resistance or seals will blow, usually the latter. Pressures well over 1000psi can occur depending on motor HP.

[Terry_Burrows]

carpet guy was your pump a white one because Derek said they were a problem,but the motor thats in mine now
is supplied by pumptec complete

new look I will ask them to check the regulater thanks! machine still with them!
but pressure gauge would say more than 400psi which it dont? but they said they will check it!

[CleanerCarpets]

pressure gauge wont say more than 400 psi, it measures the pressure in the regulator not the pump head itself which is part of the problem, all will look ok, you will still be able to adjust the pressure but the pressure in the head is too great, pushing out an o ring

all they have to do is take the head apart carefully so they can see how the o rings are placed when it comes apart, it only takes one to be slightly pushed off its little ingress to make the pump head leak

[Terry_Burrows]

thanks new look but according to derek it will show higher pressure on the gauge it is only set at 400psi
any thing higher or say 600psi will damge the machine,thats there words anyway,but he assures me they will
