Ross Torqmotor specs

[Graeme]

I have an hydraulic motor for which I have been unable to find specs. It was fitted to a 4" auger that I bought s/h 10-12 years ago and I'm hoping its capable of running at close to 540 rpm to drive a 120 L/min boom spray pump.
On the label it has:
MK050
D/C 2 01 96
Part No. MK031009AAAB.

Can anyone help with the specs - max rpm and flow rate and pressure ranges? The AB on the end refers to its 2-bolt flange.

Thanks.

I mite have some old Ross literature at work, tho that number dosn't ring a bell. Can look when go to work monday.

Any idea the HP requirement of the boom spray?? What do you plan on driving it with?
