Farmi wp30

[Hock]

Hi does any one have a farmi wp 30 wood processors that runs  on a petrol engine. Iv been trying to convert my from pto to engine but can’t find out what hydraulic pump to use I even tried the manufacturers ?

Do you mean for the hydraulic feed controls ?.

 

I'm sure the petrol engine just uses pulley sizes to change the speed of 3000rpm but keep most of the other parts standardized.

Yes the pump that goes on the engine and feeds the other pumps it’s a different one that’s on the pto  I cant find out the flow rate iv spoken to the manufacturer and they don’t know they think 37 to 40 litre per min but not sure ?

If they're being a bit cagey, i think they stopped making them about 5 years ago.

 

Best to get the details off the original petrol, you can then calculate a replacement as it could be a dual pump arrangement.

 

If it's direct drive and no pulley or belt 3000 rpm X 12cc = 36 lpm.

 

If you're running it off a tractor why not just adjust the pipework and put quick connections on the rear of the processor and use detachable connections to you tractor hydraulics.

 

Keeps the processor almost stock and easier to sell instead of butchering the metalwork and petrol engine setup.

 

PTO hydraulic will require shaft, gearbox mounting etc to get that flow and will get complicated very quickly.

Thank for the calculations .

I had a wp30. The engine direct drives the pumps. No pulleys or belts.

 

Mine had a single, single stage pump.

 

Manual says 200 bar max 

 

Look at pto pump for numbers to get spec. But you need the gearbox ratio to convert per rpm.

 

 

I have one pic of the pump. Looking at it I would say its a type 2 pump. That alone limits its max cc per rev.

40 lpm £205, not sure about the pressure.

 

But personally I'd run it off the tractor hydraulics, depends on the tractor obviously.

This is an OEM pump but with a diverter added by me.

Whilst I don't know his reasoning for wanting to switch from petrol to tractor.

 

You could always swap out the petrol engine for a similar sized diesel if it's cost savings your after ?. Providing it's the same HP, they should be the same rpm etc.
