INSTALLATION
Hydraulic Connections
Use 11/2wraps of teflon tape (or suitable thread sealant) on all threads, leaving the first complete
thread free of tape to ensure that the tape does not shed into the hydraulic system, causing
damage. Trim loose ends.
aWARNING
To ensure proper operation, avoid kinking or tightly bending hoses. If a
hose becomes kinked or otherwise damaged, it must be replaced.
Damaged hoses may rupture at high pressure, causing personal injury.

2. Install a 0-10,000 psi (700 bar) pressure gauge into the gauge port (A).
3. Thread hydraulic hose in the .375-18 NPT valve outlet port (B).
4. Connect a return line by threading a hose into the return to tank port (C).
PUJ-1400B/E, PUJ-1401B/E Models (Figure 3)
1. Remove the shipping plug from the valve advance port (D). Install a gauge adaptor into the
.375-18 NPT advance port (D).
2. Install a 10,000 psi (700 bar) pressure gauge in the gauge adaptor top port.
3. Install a hydraulic hose into the adaptor end port (.375-18 NPT). Connect the hose half coupler
to the cylinder advance half coupler. Firmly hand tighten the coupler collar. DO NOT use
tools to tighten the coupler halves.
4. Thread another hose into the retract port (E) on the control valve. Connect the hose half
coupler to the cylinder retract half coupler.
PUD1100B/E, PUD-1101B/E Models
1. The pump-to-cylinder hose attaches directly to the outlet port of the control valve.
2. The electric valve is controlled automatically with the electric motor. The cylinder advances
when the pump is activated and retracts when the pump switch is released.
3. If a gauge is desired to monitor system pressure, a gauge adaptor must be installed into the
outlet port. Install a 0-10,000 psi (700 Bar) pressure gauge into the gauge port of the gauge
adaptor.
Valve Mounting (Figure 4)
1. Remove the plate (item D43918098).
2. Verify that the connector is installed in the pump. If it is
not, install the connector, taking care to avoid shearing the
seals.
.3. Mount the valve, taking care to avoid shearing the seals.
Adding Oil (Figure 5, page 4)
Check the oil level by unscrewing and removing the vent/fill
plug (F). Add Enerpac hydraulic oil until the oil level is 1/2
inch (1cm) below the vent/fill opening.
IMPORTANT: Add oil only when all system components
are fully retracted, or the system will contain more oil than the reservoir can hold.

OPERATION
NOTE: To avoid power losses between the electrical outlet and pump motor, use the
shortest possible extension cord. The pump motor will function at low voltage, but
motor speed and oil flow will be reduced.
1. Check all system fittings and connections to be sure they are tight and leak free.
2. Check the fluid level and add fluid, if necessary.
3. Open the pump vent plug (F) located on the front right corner of the reservoir by turning it 1 or
2 complete turns.
aCAUTION
The vent plug must be open whenever the pump is running.
Switch Operation (Figure 6)
The "B" version requires a 15 amp, 120 V. grounded 1 Ph. circuit. The "E" version requires 220
V. 1 Ph. The pump power cord is 5 ft. (11/2meters) long.
1. The pump switch is located on the side of the shroud. It is a three position switch, top detent is
"ON", middle is "OFF", bottom is momentary on "MOM". Pressing the top "ON" position
activates the electrical circuit, but does not turn the pump motor on. The pump motor is
activated by the pendant switch (G).
2. Pressing the lower portion of the switch will activate the pump motor as long as the switch is
held down. Releasing the switch stops the pump. This momentary position is used as an
alternate to the pendant control.
Pump Control Valve
PUJ-1200B/E and PUJ-1201B/E models
The pump control valve directs hydraulic fluid output or return from the hydraulic system
components. These models have 3 way, 2 position valves.
Valve positions are shown in Figure 7: 1 - Advance 3- Retract.
To advance the cylinder, shift the valve to the advance position (1) and press the pendant switch.
The cylinder will advance until the pendant switch is released.
To retract the cylinder, shift the valve to the retract position (3). The cylinder will retract with or
without the pump running.

PUJ 1400B/E and PUJ-1401B/E Models
Control valves on PUJ-1400B/E and PUJ-1401B/E pumps are 4-way, 3-position, for use with
double acting cylinders where advance and retract are hydraulically actuated.
Valve positions are shown in Figure 7: 1-Advance 2- Retract 3- Neutral.
In each position the cylinder movement is controlled by the pendant switch.
PUD-1100B/E and PUD-1101B/E Models
The PUD-1100B/E and PUD-1101B/E operate single-acting cylinders where the hold function is
not necessary.
Pressing the pendant switch starts the motor and advances the cylinder. When the switch is
released, the cylinder will retract.
Thermal Relay (All models)
To protect the pump from damage, an internal relay switch shuts off the motor when the oil
temperature reaches 150°F(65°C). When the temperature drops to 130°F(54°C) the relay will
automatically reset.
Air Removal
When the hydraulic system is connected for the first time, air will be trapped in the components.
To ensure smooth, safe operation, remove the air by running the system through several complete
cycles without a load on the cylinders. When cylinders advance and retract without hesitation, the
air is vented from the system.
aWARNING
To avoid injury and equipment damage, do not continue pressurizing
cylinders after they reach maximum travel or maximum operating pressure.
RELIEF VALVE ADJUSTMENT
(PUJ-1400B/E and PUJ-1401B/E models are not equipped with external adjustable relief valves.)
The main pump relief valve is internal and non-adjustable, factory set for 10,000 psi (700 Bar)
maximum operating pressure.
An additional external relief valve is located under a hex cap on the right side of the pump. The
external relief valve is adjustable from 10,000 psi (700 bar) down to 2000 psi (140 bar).
Operating pressure limits can be reduced below 10,000 psi (700 bar), but not above 10,000 psi
(700 bar).

Adjusting the Relief Valve Setting
1. Install a gauge as directed in the installation instructions on page 3.
2. Install a plug in the valve outlet port.
3. Remove the hex cap (H) covering the relief valve
adjustment screw.
4. Using an allen wrench, turn the adjustment screw
counterclockwise one full turn.
5. Turn the pump "ON" and run the pump motor,
watching the gauge reading for the maximum
pressure. Stop the pump.
6. Continue to adjust the setting until the desired
pressure is attained.
7. Check the setting by running the pump several times.
If the gauge reading is the same each time, the valve
setting is stable. Replace the hex cap to cover the
adjusting screw.
NOTE: To get the most accurate relief valve setting,
start at a lower pressure and adjust up to
the desired relief valve setting.
aWARNING
To avoid equipment damage and personal injury, do not attempt to exceed
10,000 psi (700 bar) maximum operating pressure.
MAINTENANCE
Checking the Oil Level
Check reservoir hydraulic oil level every 40 hours of operation. Add oil when necessary to bring
the level to 1/2" (1 cm) below the fill opening. Use only Enerpac hydraulic oil. The use of other
oils or fluids may damage your system, and will void your Enerpac warranty.
Changing the Oil (Figure 9)
Completely drain the reservoir after every 100 hours of operation. Refill with new hydraulic oil.
If pump is operated in very dusty areas or at high temperatures, drain and refill more frequently.
1. To drain the reservoir, remove the vent/fill plug (F) from the top right hand corner of the
reservoir.
2. Tip the pump until all old oil is drained.
3. Refill with new oil through the same opening. Reservoir capacity is .75 gal. (2,8 l) or 1.5 gal.
(5,7 l) depending on model.
4. Replace fill plug (F).
Cleaning the Reservoir
The pump reservoir can be removed for cleaning. If the pump is constantly used in an extremely
dusty environment, the reservoir should be cleaned once a year.
1. Drain the reservoir as described in steps 1 and 2 in "Changing the Oil".
2. Remove the six screws securing the shroud to the reservoir. Lift the shroud off the reservoir.
A foam cushion wraps around the motor to keep electrical wires away from the motor. Use
caution to avoid damaging or pulling wire connections off the terminals.

3. Remove the eight screws holding the pump to the reservoir. Lift the pump off the reservoir and
remove the gasket.
4. Thoroughly clean the reservoir with a suitable solvent. Use a soft bristle brush to clean the two
pick-up screens.
5. Re-assemble the pump and reservoir, installing a new gasket. Position the shroud over the
motor with the shroud handle facing the valve side of the pump. Install the six mounting
screws and internal/external lock washers.
If the pump requires repair work, contact a local Authorized Enerpac Service Center.
