No schematics at the moment, pump drives the main rotation motor of the Casa Grande drilling machine, very old machine that operator pull a manual lever to gain displacement of the pump. Pump control is similar to an old Kawasaki NV series with a lever at the top.
Looking for some information above Linde PV pumps.
Encounter here in PH an old unit and we plan to replace with a modern pump.
Don't know if pump controller is PC, LS or HP control.
Thanks
