1.0 IMPORTANT RECEIVING INSTRUCTIONS

Visually inspect all components for shipping damage. Shipping
damage is not covered by warranty. If shipping damage is found,
notify carrier at once. The carrier is responsible for all repair and
replacement costs resulting from damage in shipment.

2.0 SAFETY

2.1 General Hydraulic Safety Precautions

Read all instructions, warnings and cautions
carefully. Follow all safety precautions to avoid

personal injury or property damage during system
operation. Enerpac cannot be responsible for damage or injury
resulting from unsafe product use, lack of maintenance or
incorrect product and/or system operation. Contact Enerpac
when in doubt as to the safety precautions and operations. If you
have never been trained on high-pressure hydraulic safety,
consult your distribution or service center for a free Enerpac
Hydraulic safety course.

Failure to comply with the following cautions and warnings could
cause equipment damage and personal injury.

A CAUTION is used to indicate correct operating or maintenance
procedures and practices to prevent damage to, or destruction
of equipment or other property.

A WARNING indicates a potential danger that requires correct
procedures or practices to avoid personal injury.

A DANGER is only used when your action or lack of action may
cause serious injury or even death.

WARNING: Wear proper personal protective gear when
operating hydraulic equipment.

Never

set the relief valve (pumps equipped with user­adjustable relief valve only) to a higher pressure than the
maximum rated pressure of the pump. Higher settings

may result in equipment damage and/or personal injury.

WARNING: The system operating pressure must not
exceed the pressure rating of the lowest rated component

in the system. Install pressure gauges in the system to
monitor operating pressure. It is your window to what is happening
in the system.

Model ZUTP-1500

1500 Bar Electric Pump

CAUTION: Avoid damaging hydraulic hose. Avoid

sharp bends and kinks when routing hydraulic hoses.
Using a bent or kinked hose will cause severe back-pressure.
Sharp bends and kinks will internally damage the hose leading to
premature hose failure.

Do not drop heavy objects on hose. A sharp impact
may cause internal damage to hose wire strands.
Applying pressure to a damaged hose may cause it

to rupture.

IMPORTANT: Do not lift hydraulic equipment by the
hoses or swivel couplers. Use the carrying handle or
other means of safe transport.

CAUTION: Keep hydraulic equipment away from
fl ames and heat. Excessive heat will soften packings

and seals, resulting in fl uid leaks. Heat also weakens
hose materials and packings. For optimum performance do not
expose equipment to temperatures of 65°C [150°F] or higher.
Protect hoses and cylinders from weld spatter.

DANGER: Do not handle pressurized hoses. Escaping
oil under pressure can penetrate the skin, causing
serious injury. If oil is injected under the skin, see a

doctor immediately.

IMPORTANT: Hydraulic equipment must only be
serviced by a qualifi ed hydraulic technician. For repair
service, contact the Authorized ENERPAC Service Center

in your area. To protect your warranty, use only ENERPAC oil.

WARNING: Immediately replace worn or damaged parts
with genuine ENERPAC parts. Standard grade parts will

break causing personal injury and property damage.
ENERPAC parts are designed to fi t properly and withstand high
loads.

WARNING: Do not use electric pumps in an explosive
atmosphere. Adhere to all local and national electrical
codes. A qualifi ed electrician must do installation and

modifi cation.

WARNING: Keep hands clear of moving parts and
pressurized hoses.

WARNING: These pumps have internal factory
adjusted relief valves, which must not be repaired or
adjusted except by an Authorized Enerpac Service

Center.

WARNING: To prevent damage to pump electric motor,
check specifi cations. Use of incorrect power source
will damage the motor.

2.2 Safety Precautions - Model ZUTP-1500 Pump

DANGER:

may result in serious personal injury or death!

• Always wear eye protection, gloves and boots when operating
the pump.

• High pressure hydraulic equipment can be very dangerous if
misused. Keep away from oil leakages at high pressure. Liquid
escaping from highly pressurized equipment has suffi cient
power to penetrate the skin, which can cause blood poisoning.
In the case of such an accident, seek IMMEDIATE medical
attention.

• Never attempt to disconnect a hydraulic
coupler while it is under pressure.

• Never attempt to repair leaks while the
system is pressurized. Be sure system
pressure gauge indicates zero (0) psi/
bar before making any repairs.

• Never pressurize the back of a
disconnected male coupler.
Serious personal injury could
result if the coupler fails while
under pressure.

• Use caution when pressurizing a
system. Pressure can rise faster
than anticipated. Continuously
monitor the pressure gauge during pressurization. Be prepared
to stop pressurization immediately at any time.

• Before operation, ensure that quick-disconnect couplings are
properly connected by physically pulling on them.

Failure to observe the following precautions

0

0

• Allow only trained and experienced personnel to operate the
pump. Be especially careful to avoid accidental pump start-up.

• Never leave the pump pressurized and unattended. Always
depressurize before leaving the system unattended.

• Never exceed the safe working pressure for the hydraulic
hoses, tools or pump.

• The Model ZUTP-1500 pump is designed to operate at a
maximum working pressure of 21,750 psi [1500 bar]. Do not
exceed this pressure setting.

WARNING:

Do not operate the pump at pressure settings
above 21,750 psi [1500 bar]. Hydraulic components
could rupture or burst. Serious personal injury and

property damage may result!

4.0 INSTALLATION

Install or position the pump to ensure that air fl ow around the
motor and pump is unobstructed. Keep the motor clean to
ensure maximum cooling during operation.

4.1 Air Breather (See Figure 1)

A shipping plug (A) is installed in the breather port on the top of
the reservoir. Before using the pump, replace the shipping plug
(A) with the air breather (B) and adapter fi tting (C).

4.2 Oil Level (See Figures 2 and 3)

Check the pump oil level prior to start-up. The reservoir is full
when the oil level is as shown in Figure 2. If necessary, remove
the oil fi ll plug from the cover plate as shown in Figure 3 and add
oil as required.

IMPORTANT: Add oil only when all system components are fully
retracted, or the system will contain more oil than the reservoir
can hold. Reservoir capacity is approximately 1 gallon [3,8 liters].

4.3 Electrical Connections

WARNING: The pump is factory equipped with the

common electrical plug for a given voltage. Altering the
plug type should only be done by a qualifi ed electrician,

adhering to all applicable local and national codes.

• The disconnect and line circuit protection is to be provided by
customer. Line circuit protection is to be 115 percent of motor full
load current at maximum pressure of application.

• For additional information, refer to power rating on pump name
plate. Also refer to graph in Section 3.1.

4.4 Hydraulic Connections

• A female quick-disconnect fi tting (Enerpac Model BR150) is
installed at the pump oil outlet. This fi tting is rated at 21,750 psi
[1500 bar].

• Enerpac recommends the use of Enerpac HT 1500 Series
thermoplastic hoses with the Model ZUTP-1500 pump. These
hoses are rated at 21,750 psi [1500 bar]. Refer to Enerpac
instruction sheet L2733 for use, safety and maintenance
information.

WARNING: The Model ZUTP-1500 pump must be
operated only with hoses and fi ttings rated to operate

at 21,750 psi [1500 bar] working pressure. Hydraulic
hoses and fi ttings of a lower pressure rating will rupture or burst.
Serious personal injury could result!

• Before connecting hose to pump oil outlet, check that pump
pressure gauge indicates zero (0) psi/bar. If any pressure is
indicated, fully open the pressure release valve to relieve
pressure. See Section 5.1.

5.0 OPERATION

5.1 Pressure Release Valve (See Figure 4)

Valve Positions:

1. CLOSED - Flow directed to pump hydraulic outlet port.

Pressure builds when pump motor is turned on. Pump holds
pressure when motor is turned off.

2. OPEN - Pressure released to pump hydraulic reservoir.

Pressure will not build when motor is turned on.

Tank is full

when oil level

is here.
