Title: Pump Life!
Post by: Gary Webber on December 07, 2011, 08:01:53 pm
Really Sad to say RIP to my solution pump today, the poor old brushes & windings have bit the dust.  :( :( :(

Mind you my EMV Porty is  three and a half years old and the pump is the original, so Time for a new one. Anyone had a pump last longer than that (before asking usage, the machine is used six days a week usually 5-6 hours a day plus)

???????

My Ninja is over 4 years old, original pump still working well, only 1 vac pump replaced, fingers crossed.

PS, never used any kind of powder or solution in clean tank, only clean water in clean tank and always turn down pressure before starting or turning off motors

Depends on whether it is an induction or brushed rectified motor.
Always release the pressure before starting an induction motor.
Check and replace the brushes regularly every 800 hours or so on a brushed motor then it will last almost indefinitely.

My Ninja is 2.5 years old with a 500psi induction
pump and so far so good. Never use it above 450psi.
Had 3 vac motors though.First one went after 13 months.
Same one went again 8 month later, then a month later
the other on finally gave in.
Next time one goes I'm going to do it myself hopefully.
They charge £270 a pop to change them and after
 looking at them it looks quite simple.
The pump though might be a different prospect.

With an in-series config, normally vac 2 fails more than vac 1, because it's running hotter due to vac 1's exhaust being fed straight in to it.  Suppose you could can swap them round after a while to even out the wear but I've never bothered.  I used to get years out of my Ninja's motors just by not abusing them!  Just scrapped one out of my current machine which was date stamped 2003!

John if you're moderately capable with a screwdriver in your hand you can change vac motors in the Ninja no problem, and service the pump too.  Make sure you've got a couple of the foam gaskets to seal the motor on to the machine manifold.  You can often re-use them if they're in good nick but sometimes they tear trying to get them off the old motor.

The only other specialist thing you might need is a crimping tool and some 5mm bullet crimps (http://www.ebay.co.uk/sch/i.html?rt=nc&LH_BIN=1&_nkw=5mm+bullet+crimp&_sc=1&_sop=15&_trksid=p3286.c0.m301).  I can't rmember off the top of my head which way round they are... I think the male connector is on the motor wire and the female is on the wiring loom, so obviously you'll only need one or the other.

When changing vac 2 you need to re-fit the exhaust hose.  I always drill 3 holes on the motor's exhaust horn, put loads of silicone on the hose to seal it in place, pierce the hose with a bradawl and then put a long pop rivet through the holes to fix it all in nice and tight.  You don't want exhaust leaking out into the machine just in case it gets a bit damp in there!

Some vac motors come with a flange on the inlet side, which you need to remove with a hacksaw to fit on the machine.  When sawing, try to have the motor turned over so gravity lets the metal swarf fall out of the motor rather than in to it.  After sawing, hold the motor so the hole is facing the floor and tap the motor gently whilst giving it a good old clean out with a vacuum.  Sounds complicated but it isn't at all!

Cheers for that Jim is the pump a little bit
more complicated.
Just copied and pasted your last reply thanks.
Going to change vac 2 over Xmas when I get
bored and keep old one as spare.

No worries John, sounds like a plan :)

I've only ever had the 135psi shurflo pumps so I'm not sure what the differences are with your 400psi model, but in most cases it's just a case of removing fittings, changing stuff and then fixing it back together again.

My approach has always been to have a back-up plan in place like a spare machine or someone local who can fix it, should you make a balls of it when working on it!  Have always managed though, once you break the barrier and get stuck in to it :)
