Parker pto botex crane pumps

[MattyF]

Any body know what the pump flow rate for the pump is or have a link for a direct replacement?

Keep cracking the backs of the pump every other year and have three broken ones sitting in the workshop.... Wilson’s want £500 + for a new one !

Give flowfit or approved hydraulics a call.
Got a new rotator for botex of approved at nearly 200quid less than Wilson's for identical thing, just give them a serial number and they can cross reference it for you or possibly give you a slightly higher flow unit should you want one.

Thanks John was looking at eBay prices for similar items and a lot cheaper but have no idea what the flow rate , cc rate and max pressure is ! , every thing has come and broke down at once !! would there be any advantage to fitting a higher flow rate pump ?

Looks like a standard Group 3 pump. Hydraulic megastore or Flowfit should sort you out for under £150 I reckon. You should be able to work out the displacement from measuring and comparing to their charts if the codes on the back don't do it.

There is a parker part number on it but if you type it in and do a search it comes up with something completely different!

Hi ring whitehouse products at port Glasgow, they will cross reference the the part number and either supply the same parker pump or a alternative one, they are not expensive and have a very good service, order before 3pm and will be with you the monning after,

Matty I think you should be checking out the crane hydraulics, no way should the back of the pump keep cracking like that. Must be a dead circuit in there somewhere, could be in the spool block or a knackered relief valve.

Yes it could be a jammed relief valve or even  a constricted return line but also consider that the bigger 3p pumps have a lower safe working pressure once you get above about 80ml/revolution which is why if you need to maintain 200bar and 100lite/min at 1500rpm you are better off with tandem 2p series.

Thanks, I will get some one to check it out ,the relief valve was a pita a few years back , I could of messed it up further by playing with it or I have just knocked the pump reversing on full lock off the trailer draw bar putting in a fracture... which does not make sense as I recently had the whole lot moved in to a better position to prevent this.
