PAQG Models:
WARNING: On PAQG and PANG models, you must
connect an in-line directional valve to be able to release
system pressure and return oil to the reservoir. DO NOT
release pressure by disconnecting a pressurized line. Handling
pressurized hydraulic lines can result in severe personal injury
caused by sudden release of pressurized oil.
See illustration 5. For this model, the tool used must have a valve
in order to release system pressure to the reservoir. If the tool
does not have a control valve, you must install a remote directional
valve.
If the tool has a valve, thread a hose into pressure port (A) of
the pump and connect the hose to the pressure port of the tool.
Connect a return line hose from the valve to the tank port (B).
If you need to install a valve, connect a hose from the pressure
port (A) of the pump to the pressure port of the remote valve.
Connect return line hose from the valve back to the tank port (B).
Connect a hose from the valve to the tool. (Recommended Valves:
Enerpac VC Series manual, or VS/VE Series electro-actuated
control valves.)
NOTE: Hose fittings must be torqued. See Torque Specifications
Table to the left.
PANG Models: The manifold is designed for custom-made valves.
PANG models are shipped with a cover and gasket, which are
bolted to the manifold block. Remove the four bolts, the cover,
and the gasket. Bolt a valve on the manifold using the four holes
(C) in the manifold block. The mounting holes have M12 x 1,75
threads, which are 0.60" [15,2mm] deep. Connect hoses to valve
outlet ports.
5.4 Venting
This pump must always be vented prior to use. Use either the
"Vent Screw" or "Vent/Fill Plug".
a) Vent Screw: See illustration 7A, item 1. The vent screw is the
primary means to vent the reservoir when the pump is operated in
the horizontal position. It is located near the hydraulic outlet port
on top of the reservoir. To allow venting, open the screw 1/2 to
1 full turn. To avoid damaging the threads when closing the vent
screw, tighten only until the screw head slightly compresses the
O-ring. Apply only about 8-10 in-lbs [1 Nm] of torque. The vent
screw can NOT be used when pump is mounted vertically! When
mounting in the vertical position, use the vent/fill plug.
b) Vent/Fill Plug: See illustration 7B, item 2. The Vent/Fill plug is
located on the air inlet end of the pump, opposite the vent screw.
This plug serves 3 functions; vent plug, fill port, and return-to-tank
port.
To use as a vent (for vertical applications or temporary venting)
pull up on hex plug until first detent is reached (see illustration 8).
This is the vented position.
To use as a fill port, pull up hex plug past first detent and remove
plug from the reservoir. Oil level should be to bottom of port. Use
only Enerpac hydraulic oil.
To use as a return-to-tank port, remove flush plug from hex and
install compatible return line. Torque return line to 15-20 ft. lbs.
[20-27 Nm] in hex plug.
CAUTION: Pump reservoir must be vented using one
of the two vent options. Failure to do so may cause
cavitation and pump damage.
5.5 Mounting Pump
Pump can be mounted horizontally or vertically. If mounted
vertically, position pump with hydraulic outlet port(s) facing down.
a) Without Mounting Brackets: The four holes in the bottom
of the reservoir should be used for bolting through the mounting
surface into the reservoir. Use the #10 x 5/8" fasteners included
with pump, or allow no more than 3/4" [19 mm] thread engagement
into reservoir.
NOTE: A mounting bracket kit, MTB1, can be ordered from
Enerpac.
b) With Mounting Brackets: Models with brackets have model
numbers ending with the letter 'B'. The mounting bracket may be
mounted on the pump or shipped separately. To mount the bracket
on the pump, use the #10 x 5/8" fasteners included with pump, or
allow no more than 3/4" [19 mm] thread engagement into reservoir.
The pump can be mounted horizontally or vertically using the four
slots in the mounting bracket.
CAUTION: When mounting the pump in the vertical
position, the vent screw must remain closed.
5.6 Oil Level
Always check oil level with all cylinders or tools in the fully retracted
position. If they are advanced when the pump is filled, the reservoir
will be over-filled when they are retracted.
Use the low-level sight glass on the end of the pump to check the
oil level. When the pump is mounted horizontally, the reservoir is
full when oil is at the bottom of the fill port. If oil is not visible, then
oil must be added. To add oil, remove Vent/Fill plug from reservoir
(See section 5.4b).
When the pump is mounted vertically, the oil level should be
checked periodically by removing the pump and placing it on a
horizontal surface.
NOTE: Prior to mounting the pump in the vertical position, oil
volume in the reservoir must be reduced to prevent leakage
through the vent/fill plug. See the specification table on page 2 for
usable oil capacity in vertical position.
6.0 OPERATION
6.1 Oil Level
Check the oil level of pump and add oil if necessary (See
Installation section, step 5.6).
6.2 Venting Pump
Make sure the pump reservoir is vented (See Installation section,
step 5.4).
6.3 Treadle Operation (PATG Models Only):
See illustration 9.
a) To Advance Cylinder: Depress the "PRESSURE" end of treadle
and the pump will start to pump hydraulic oil to the system.
b) To Hold The Cylinder Position: The pump will stop and hold
pressure when the treadle is in the free/neutral position (treadle is
not depressed in either "PRESSURE" or "RELEASE" positions.)
c) To Retract Cylinder: Depress the "RELEASE" end of the
treadle to retract cylinder. To stop the cylinder from retracting,
release the treadle and return it to the hold position.
