On the hunt for a danfoss VPA pump??

[Boy English]

Hello to all,

 

Clutching at straws here but thought it was worth a punt..

 

For the past few months I have been searching for some spares in order to get my little forklift back up and running, the parts I need if available wouldn't be more than £100 however danfoss have stopped making spares for my model and count it as obsolete [emoji22]

 

It's a lovely tool and I'm really hoping someone may have one (or parts of one) kicking around as they were quite common on plant and agg machines.

 

After a lot of calls to various pump people I'm still drawing a blank on all fronts and am running out of channels to follow.

 

Here is a pic incase you think you see one

 

Inside the shiny bit is 7 pistons and I need 3 to get going again..

 

Any help greatly appreciated [emoji106]

Hi looking at your machine it looks mower based, may be try a grass machinery breakers, or ring whitehouse products at port Glasgow with pump make and number they may have one or cross reference it with something else, I know what you are up against as been in same position my self looked for months then found 3 on a shelf in a small hydraulic co in Leeds,

Failing finding a direct replacement  as per spuddog's suggestion: Is it a single or tandem  variable displacement piston pump? Is it belt driven? If so they are relatively expensive  but Parkers PV16 series pumps will do the same job, hydraulic fittings will be different and you will probably need an outrigger bearing.

Cheers chaps, I've been down the mower route but it's somewhat different, I've got 3 mower pumps in the shed from various ransomes in the hope I could cobble something together but the space is so tight it's not going to take anything but the original without some serious work, the diesel tank is built into the chassis and the whole thing just screams nightmare to reconfigure given the size of it..

It's a single pump driven direct via a fibre coupling, I have found details that the Parker can be used as a replacement but again it's going to require cutting about to get it in, it's not really a piston pump as such although that was my original assumption.

Since the evenings have become darker I've been playing in my shed with the burner going and got sick of looking at it so I decided to have a last ditch attempt with the original.

On investigation I believe (sort of) that the pistons actually don't create pressure and only really direct fluid variably for fluid flow / speed, there is a normal gear pump in there also which is either a charge pump or hopefully is responsible for pressure.

If it is then all I can see will happen by my 3 pistons being knackered is my speed will be reduced, the issue we've had is every few months these 3 seize midway in the bore and create a knock on the pedal, no damage occurs but it prevents you from using the forward / reverse pedal to either extreme.

In a hope and prey type manner Instead of removing them, cleaning up and refitting I've knocked them in, ie they are now unable to cause the knock and if I'm correct which is very much a 50/50 it will work fine just slower, while not ideal is a lot better than being an ornament.

Either way i don't believe It can make the situation worse so I'm giving it a shot, I refitted the pump last night and should have time to pipe it up later so will keep you posted [emoji106]

It wold appear (not having used it for a days graft) that I had a feat of genius !!

I tried it as above however the damaged pistons came out under pressure and after a few minutes caused the same issues as before.

At 8oclock at on a Friday
I attack'd the bastards with the use of a spot weld and after reassembley it seems all fine, a little slower but all good..

You may see a picture of me smiling or crying in the near future [emoji846]

Did you find that VPA 20 Danfoss pump? I need to peplace it on my Dynapac LR100 compactor too. Please let me know.
