NOTE: Valve block or treadle should be restrained when torquing
fittings. The reservoir base should NOT be bolted down or
restrained to counteract the fitting installation torque.
NOTE: Use 1 1/2 wraps of Teflon tape on 3/8 NPTF hose fittings
only, leaving the first complete thread free of tape to ensure that
pieces of tape do not break off and enter the system. Do not use
thread sealant on BSPP or SAE fittings.
PAT Models
See Figure 2. Thread hose into outlet port of pump. The outlet port
(A) is located on the opposite end of the pump from the air inlet
connection. Hose fittings must be torqued. See the torque
specification table.
PAM Models
See Figure 3. Thread hoses into pressure port (A) and tank port
(B) of the pump. Hose fittings must be torqued. See the torque
specification table on this page.
Warning: On the PAC model 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 the sudden release of pressurized
oil.
PAC Models
See Figure 4. Thread hose into pressure port (A). Connect hose to
the pressure port of the remote valve. You must use an in-line
directional valve to release system pressure and return oil to the
reservoir. (Recommended Valves: Enerpac VC Series Manual or
VS/VE Series electro-actuated control valves). Connect a return
line hose from the valve back to the tank port (B) of the pump.
Connect a hose from the valve to your tool or cylinder. Hose fittings
must be torqued. See the torque Specification Tables.
PAS Models
See Figure 5. The shipping cover and gasket are bolted to the
manifold. Remove the four bolts, the cover, and the gasket.
The manifold is designed to accommodate standard CETPO3 or
DO3 valves. Mount valve per manufactures instructions. See
Figure 5, (C). Connect hose from pressure port (A) to pressure
port of the tool or cylinder. Connect return or retract line from tool
or cylinder to the return tank port (B) of the pump. Hose fittings
must be torqued. See the torque Specification Table.
5.0 VENTING
Turbo II pumps must always be vented prior to use. Use either the
"Vent Screw" or "Vent/Fill Plug".
5.1 Vent Screw
Torque See Figure 6A. The vent screw (item 1) is the primary means to
vent the reservoir when the pump is operated in the horizontal

until the screw head contacts the reservoir cover. The vent screw

mounting in the vertical position, use the vent/fill plug.
13,5-16
5.2 Vent/Fill Plug
See Figure 6B. The Vent/Fill plug (item 2) 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 Figure 7). This
is the vented position.
To use as a fill port, pull hex plug up past the first detent and
remove the plug from the reservoir. The oil level should be to the
bottom of the port. To protect your warranty, use only Enerpac
hydraulic oil.
To use as a return-to-tank port, remove the flush plug from the hex
and install a return line in the 3/8 -18 NPTF port. Torque return line
to 15-20 ft. lbs. [20-27 Nm] in hex plug.
6.0 MOUNTING PUMP
The pump can be mounted horizontally or vertically. If it is
mounted vertically, position the pump with the hydraulic outlet
port(s) facing down.
6.1 Without Mounting Bracket
Use the four #10 x 5/8" fasteners included with the pump and allow
no more than 3/4" [19mm] thread engagement into the reservoir.
NOTE: A mounting bracket kit, MTB1, can be ordered from
Enerpac. All pumps come with mounting brackets.
6.2 WITH MOUNTING BRACKET
Models with mounting brackets have model numbers ending in the
letter "B". The mounting bracket may be attached to the pump or
shipped separately. It can be attached to the bottom of the
reservoir using the four #10 x 5/8" fasteners included with the
pump. Allow no more than 3/4" [19mm] thread engagement into
the reservoir. The pump can be mounted horizontally or vertically
using the four slots in the bracket.
7.0 OIL LEVEL
Always check the 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 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 the vent/fill plug from reservoir and
fill the reservoir to the bottom of the port.

CAUTION: Pump reservoir must be vented using one
of the two vent options. Failure to do so may cause
cavitation and pump damage.
CAUTION: When mounting the pump in the vertical
position, the vent screw must remain closed.
