Industrial● Power supply is three phase (from 200V).
● Various valves and accessories can be stacked for many applications.
● Caster can be installed as option.
● Structure is very simple because there is no piping in the pump body.
● When continuous operation, please use oil cooler (on request) to prevent oil temperature rise.
● Pump parts Assy are available on request.
