Prime the Pump
1.
Perform the
Pressure Relief Procedure
on
page 10.
2.
Attach the hydraulic system to the fluid outlet line
(M) and verify all connections and fluid lines are
tight.
a.
Close the shutoff/bleed valve (G) and open the
fluid pressure relief valve (H).
b.
Set the pressure regulator (D) to
0 PSI/MPa/bar.
NOTE:
The pressure regulator (D) and bleed-type mas-
ter pneumatic valve (C) both affect the pump cycle rate.
After the inlet pressure is set, the bleed-type master
pneumatic valve (C) can serve as a speed control.
3.
Turn on the air at the bleed-type master pneumatic
valve (C). Slowly increase the pressure using the
pressure regulator (D) to slowly cycle (less than 80
cycles per minute) the Intensifier pump (E).
4.
Keep the pump cycle rate at less than 80 cycles per
minute. The pump is primed when discharge from
the pump has transitioned from air, to bubbly fluid,
to pure fluid.
Build Pressure
1.
Close the fluid pressure relief valve (H) and open
the fluid outlet valve (G) that is connected to the
hydraulic system. Bleed the hydraulic system of all
air per the manufacturer’s recommended practice.
2.
Turn off the air at the pneumatic valve (C) and set
the pressure regulator (D) to 0 PSI/MPa/bar. Seal
the hydraulic system per the manufacturer’s recom-
mended practice. You are now ready to build pres-
sure.
3.
Turn on the air at the bleed-type master pneumatic
valve (C) and slowly increase pressure with the
pressure regulator (D) until the desired pressure is
produced in the hydraulic system.
NOTE:
Hydraulic pressure increases proportionally to
inlet pressure up to the maximum working pressure of
the pump.
4.
After pressurization of the hydraulic system is com-
plete, perform the
page 10.
NOTICE
Pump runaway may occur if the pressure regulator is
opened too far for pressure settings, causing damage
to the packing seals.
