ZU4 Electric Pumps
High-pressure pumps designedspecifically for tough
construction applications.
Motor lip seal
Replaceable pistoncheck valves
Self-priming, high-flow 1st stage pump
Balanced eccentric
Heavy-duty bearings
Oil bath
Introducing the Z-Class power pumps from Enerpac—pumps that run cooler, use less electricity and are easy to service.
Enerpac has used the latest metallurgical, bearing andseal technologies to produce a pump whose features and benefits far surpass the electric pumps that areavailable today. By reducing the number of moving
parts, improving flow dynamics and decreasingfriction, Z-Class pumps will stay on the joblonger, require less energy to operate andwhen needed, have lower service costs.
Z-Class electric pumps fromEnerpac—simply the best pump you will ever use.

ZU4 Electric Pumps
Heavy-duty composite shroudprotects electric motor and keyelectrical components fromenvironmental contamination, rain anddebris and provides a non-conductiveergonomic handle for the operator.
Low-voltage pendant features sealedswitches and operates at 15 vdc forimproved operator safety.
Easily accessible brush cavity allowsrapid brush replacement in the field.
Brush design lasts 4-times longer thancurrent designs and features “auto-stop”shunt to prevent commutator damagefrom normal brush wear.
Reduced current draw extends brushlife and reduces electrical load onelectrical circuits and generators.
Optional back-lit LCD- pump usage information, hour and
cycle counts- low-voltage warning and recording- offers self-test and diagnostic
capabilities- information displayed in 6 languages- pressure read-out (when used with
the optional pressure transducer)- adjustable trigger pressure setting
(when used with the optional pressure transducer)
An Innovation in Pump DesignZ-Class Pumping Element
Highly efficient design providesincreased flow rates, reduced heatgeneration and a decrease in powerconsumption. This means improved tool speed and increased service life—which results in higher productivity andlower operating costs.
Heavy-duty bearings extend pump lifeby reducing friction, reducing surface-loading and lowering bearing stresses.
Pump cavity oil bath extends pump lifeby reducing heat, improving lubricationand reducing wear.
Self-priming, high-flow 1st stagepump increases pump performance by super-charging the 2nd stage pistonpump—improving oil flow in both hotand cold weather operation.
Balanced rotating componentsreduce vibration creating a smootherrunning pump—reducing wear, frictionand sound levels.
Replaceable piston check-valvesincrease service life of major pump components.

• High-strength, molded composite shroud protectsmotor and electronics, while providing an ergonomic,non-conductive handle for easy transport
• Low-voltage pendant provides additional safety for theoperator (remote control units)
• LCD readout provides a number of diagnostic andreadout capabilities never before offered on a portableelectric pump (included with electric valves, optionalwith manual valves)
� Designed to be tough,the ZU4 Series steelreservoirs will take theabuse of today’sconstruction sites.
BASIC PUMP TYPES
Select the model that suits yourapplication. For special requirementscontact your Enerpac office.
Manual Valve• Ideal choice for most applications• Manual valve control, for single-acting
or double-acting applications• Motor control on shroud
Solenoid Valve• Ideal for lifting applications and where
remote control is required• Motor runs continuously on pumps with
VE33 and VE43 valves. With VE32 valve,motor only runs during the advancefunction, while holding and retracting, themotor is off
• Low-voltage control pendant with 10 ft.cord for remote motor and valve operation
� COMMON PUMP MODELSFor technical information and otheroptions see next page.
Dump Valve• Ideal for punching, crimping and cutting• For use when load-holding is not required• Low-voltage control pendant with 10-ft.
cord controls valve and motor
Manual Valve with Pendant• For light production and lifting
applications• Manual valve control for single-acting
or double-acting cylinders• Low-voltage control pendant with
10-ft. cord for remote motor operation

ZU4 Pump Application
The ZU4 pump is best suitedto power medium to large
size cylinders or hydraulic tools, orwherever high speed, intermittentduty cycle is needed.
Patent-pending Z-Class technology provides high by-pass pressures forincreased productivity, specifically inapplications using long hose runs andhigh-pressure drop circuits like heavylifting or certain double-acting tools.
Its lightweight and compact designmake it ideal for applications whichrequire easy transport of the pump. It utilizes a universal motor which will work well on long extension cords or generator driven electricalpower supplies.
For further application assistancecontact your local Enerpac office.
