Domestic Application

SR Hydraulic Pump series are air-over -hydraulic pumps
operated with compressed air. Pump's discharge
pressure is controlled by operating air pressure. Oil flow
rate increases at the low hydraulic pressure and
decreases at the high hydraulic pressure.

When air pressure is balanced with hydraulic pressure, the
pumps stops automatically, and will start automatically
when hydraulic pressure decreases.The pump,then
operates continuosly until air pressure reaches
equilibrium with hydraulic pressure.
