4.0 INSTALLATION
4.1 Connecting the Pump
Figure 6
1. Remove shipping plug(s)
from pump outlet port(s).
2. Adjust the relief
valve to the desired
hydraulic pressure limit.
See Section 7.0 for
instructions.
3. Connect hose(s) to
pump. To seal threads,
use anaerobic thread sealer,
Teflon
® paste or Teflon ®
tape.
IMPORTANT: When using Teflon ® tape, apply the
tape one thread back from the end of the fitting to
prevent pieces of tape from entering the hydraulic
system. See Figure 6.
4. Install a pressure gauge in-line from the pump for
added safety and better control.
5. Connect the hose(s) to your cylinder or tool.
• For single-acting cylinders, connect one hose
from the pump to the cylinder.
• For double-acting cylinders, connect two hoses.
Connect one hose from port (A) of the pump to
the advance port of the cylinder. Connect another
hose from port (B) of the pump to the retract port
of the cylinder.
Models P-80 and P-801 only: If an external
pressure reducing valve is being used in the
circuit, connect the tank port of the valve to the
return-to-tank port on the pump.
Note: Cylinders, hoses and accessories shown
in Figure 5 are sold separately and not included
with pump. Refer to the Enerpac catalog for a
complete description of available components and
accessories. The exact components required for
your system will vary, depending on application and
other factors.
4.2 Pump Venting
The ULTIMA series hand pumps are designed
for non-vented operation. The oil fill plug can be
loosened if needed to vent air from the system but
should be fully installed before using the pump.
IMPORTANT: To prevent contaminants from entering
the hydraulic system, do not operate pump with oil fill
plug loosened or removed.
