Rev. 0 December, 2014

WARNING

To help prevent personal injury,

GENERAL

• Always wear eye protection whenever operating hydraulic equipment.

• Always wear hearing protection as required. Refer to the sound level (dB[A]) chart.

• Operation, repair, or maintenance of hydraulic equipment should be performed by a quali-

edpersonwhounderstandstheproperfunctionofhydraulicequipmentperlocaldirec-

tives and standards.

• Hydraulic equipment must be assembled correctly and then checked for proper function

before use. Use hydraulic components of the same hydraulic pressure ratings. An appro-

priate hydraulic pressure gauge is recommended to monitor pressure.

• Neverplaceyourhandsorotherbodypartsnearahydraulicuidleak.Neveruseyour

handsorotherbodypartstocheckforapossibleleak.Highpressureuidcanbeinjected

under your skin causing serious injury and/or infection.

• Highpressureuidispresentthroughoutahydraulicsystem.Alwaysusecautionwhen

operating, repairing, or maintaining this equipment. Before beginning any work on any

hydraulic system component, stop the equipment, disconnect from its power source, and

relieve all pressure in all parts of the system. Do not tamper with the internal hydraulic

relief valve settings.

• Avoid exposing hydraulic equipment (especially hoses) to extreme high or low tempera-

tures. Damage to equipment or failure may result and cause loss of control or injury to the

operator.

• Exercisecautiontoavoidtheriskofre.

• Do not drop any hydraulic system components. Damage to the equipment and/or injury

may result.

• Avoid slipping or falling by cleaning up any oil spills.

• Avoid back injury by always lifting equipment carefully.

• It is strongly recommended to view the Power Team Hydraulic Safety video tape before

using hydraulic equipment.

POWER SUPPLY

Electric

Electrical Shock or Electrocution

• Anyelectricalworkmustbedoneandtestedbyaqualiedelectricianperlocaldirectivesandstan-

dards.

• Disconnect the pump from the power supply and relieve pressure before removing the motor case

cover or performing maintenance or repair.

• Never use an ungrounded power supply with this unit.

• If the power cord is damaged or wiring is exposed, replace or repair immediately.

• Changing the voltage on this unit is an involved, and if improperly performed, hazardous proce-

dure.Consultthemanufacturerforspecicinformationbeforeattemptinganyrewiring.

• All PE55 Series pump motors must be wired for clockwise (CW) rotation when viewed from the lead

end (top) of the motor.

Rev. 0 December, 2014

• Check the total amperage draw for the electrical circuit you will be using. (For example: Do not plug

a pump or pumps that may draw 25 amps into a 20 amp fused electrical circuit.)

• Do not attempt to increase the powerline capacity by replacing a fuse with another fuse of higher

value.Overheatingofthepowerlineandthepossibilityofarewillresult.

• Torewireamotorfromonevoltagetoanotherorwhenaowcontrolvalveischangedbetween

manual and solenoid, consult the electrical schematic in the pump’s parts list.

• Electric pumps should never be exposed to rain or water which could cause personal electrical haz-

ard.

• Avoid conditions which can cause damage to the power cord such as abrasion, crushing, sharp

cutting edges, or corrosive environment. Damage to the power cord can cause an electrical hazard.

HYDRAULIC HOSES AND FLUID TRANSMISSION LINES

• Avoid straight line tubing connections in short runs. Straight line runs do not provide for expansion

and contraction due to pressure and/or temperature changes. See diagrams in “Set-up Instruc-

tions” section of this form.

• Eliminate stress in the tube lines. Long tubing runs should be supported by brackets or clips.

Tubesthroughbulkheadsmusthavebulkheadttings.Thismakeseasyremovalpossibleand

helps support the tubing.

• Before operating the pump, all hose connections must be tightened with the proper tools. Do not

overtighten. Connections should only be tightened securely and leak-free. Overtightening can

causeprematurethreadfailureorhighpressurettingstosplitatpressureslowerthantheirrated

capacities.

• Should a hydraulic hose ever rupture, burst, or need to be disconnected, immediately shut off the

pump and release all pressure. Never attempt to grasp a leaking pressurized hose with your hands.

Theforceofescapinghydraulicuidcouldcauseseriousinjury.

• Donotsubjectthehosetopotentialhazardsuchasre,sharpsurfaces,extremeheatorcold,or

heavyimpact.Donotallowthehosetokink,twist,curl,crush,cut,orbendsotightlythattheuid

owwithinthehoseisblockedorreduced.Periodicallyinspectthehoseforwear,becauseany

of these conditions can damage the hose and possibly result in personal injury. Never repair with

tape.

• Do not use the hose to move attached equipment. Stress can damage the hose and possibly cause

personal injury.

• Hosematerialandcouplersealsmustbecompatiblewiththehydraulicuidused.Hosesalsomust

not come in contact with corrosive materials such as creosote-impregnated objects and some

paints. Hose deterioration due to corrosive materials can result in personal injury. Consult the

manufacturer before painting a hose. Never paint a coupler.

PUMP

• Do not exceed the hydraulic pressure rating noted on the pump nameplate or tamper with the in-

ternal high pressure relief valve. Creating pressure beyond rated capacities can result in personal

injury.

• Beforereplenishingtheuidlevel,retractthesystemtopreventoverllingthepumpreservoir.An

overllcancausepersonalinjuryduetoexcessreservoirpressurecreatedwhenthecylindersare

retracted.

• Always shut off the motor or engine and relieve pressure before breaking any connections in the

system.

• The motor or engine is the major part of the weight of the pump. Always take this into consideration

when lifting or moving the pump.

Rev. 0 December, 2014

CYLINDER

• Do not exceed the rated capacities of the cylinders. Excess pressure can result in personal injury.

• Do not set poorly balanced or off-center loads on a cylinder. The load can tip and cause personal

injury.

• Read and understand the cylinder operating instructions and warning decals before

using the cylinder.

DANGER

A double-acting cylinder or ram must have both hoses and all couplers securely connected to both

ports. If one of the two ports is restricted or becomes disconnected, pressure will build and the cylin-

der, hose or coupler can burst, possibly causing serious injury or death.

HYDRAULIC FLUIDS

• Properlydisposeofalluids,components,andassembliesattheendoftheirusefullife.

• Hydraulicuidshouldbecompatiblewithallhydrauliccomponents.

HYDRAULIC PUMP

5,000 OR 10,000 PSI

Denition: A hydraulic pump delivers hydraulic uid under pressure through the use of compressed air, an elec-

tric motor, or a gas engine as a power source.

NOTE

• Carefully inspect the pump upon arrival. The carrier, not the manufacturer, is responsible for any

damage resulting from shipment.

• The customer can choose from a variety of motors, controls, reservoirs, and other options. These

instructions will include directions for options that your particular pump may not have.

• Do not change motors without consulting the pump manufacturer’s Technical Services Department.

Rev. 0 December, 2014

SET-UP INSTRUCTIONS

1. Filling The Pump Reservoir.

NOTE

Mostpumpsareshippedwithouthydraulicuidinthereservoir.Hydraulicuidmayhavebeen

shippedwiththepumpinaseparatecontainer.Ifhydraulicuidisneeded,use215SSU@100°F

(47cSt@38°C)hydraulicuid.

A. Clean the area around the ller cap to remove all dust and grit. Any dirt or dust in the hydraulic uid can

damage the polished surfaces and precision-t components of this pump.

B. Retract all cylinder(s) to their return position.

C. Remove the ller cap and insert a clean funnel with a lter. Fill the reservoir with hydraulic uid to 1”

(25,4 mm) from the cover plate, replace the ller cap.

2. Hydraulic Connections

Remove the thread protectors or dust covers from the hydraulic ports if applicable. Clean the areas around the

uid ports of the pump and cylinder. Inspect all threads and ttings for signs of wear or damage, and replace as

needed. Clean all hose ends, couplers and union ends. Connect all hose assemblies to the pump and cylinder.

Use an approved, high-grade pipe thread sealant to seal all hydraulic connections. Tighten securely and leak-

free but do not overtighten.

Hydraulic lines and ttings can act as restrictors as the cylinder or ram retracts. The restricting or slowing of the

uid ow causes back pressure that slows the cylinder’s or ram’s return. Return speed also varies because of

the application, condition of the cylinder or ram, inside diameter of hose or tting, length of the hose, and the

temperature and viscosity of the hydraulic uid.

3. Bleeding The System

After all connections are made, the hydraulic system must be bled of any trapped air. Refer to the diagrams

below.

With no load on the system and the pump vented and positioned higher than the cylinder or ram, cycle the sys-

tem several times. Check the reservoir for possible low uid level and ll to proper level with approved, com-

patible hydraulic uid as necessary (see “Filling The Pump Reservoir” section under Set-up Instructions).

Rev. 0 December, 2014

IMPORTANT

Some spring return cylinders or rams have a cavity in the rod which forms an air pocket. This type of

cylinder or ram should be bled when positioned upside down or lying on its side with the port facing

upward.

PUMP OPERATION

1. OPERATING THE PUMP FOR THE FIRST TIME:

A. Valve and hose connections must be tight, and the reservoir must be lled to the proper uid level. Start

the motor.

B. Jog the pump several times to build pressure.

C. Run cylinder out to its full travel several times to eliminate air from the system. For more complete

instructions, refer to the section titled “Bleeding The System” under Set-up Instructions.

D. With the cylinder(s) retracted completely, check the uid level in the reservoir and add uid if neces-

sary. Refer to “Filling The Pump Reservoir” under Set-up Instructions.

E. The pump is now ready to be put into regular operation.

DANGER

When lifting or lowering a load, the load must be under operator control at all times and others must be

clear of the load. Use blocking and cribbing to guard against a falling load. Do not drop the load. The

use of a load lowering or metering valve is recommended in addition to the pump directional control

valve.

OPERATION

Neutral (HOLD): When neither solenoid is energized, uid from pump is directed back to tank and uid from

cylinder is checked in the cylinder.

Advance: When solenoid “B” is energized, uid from pump is directed through pressure port to cylinder.

Return: When solenoid “A” is energized, uid from the pump and from the cylinder is directed back to tank.

NOTE

Pressure holds without loss when shifted from cylinder port to the neutral (HOLD) position.

Rev. 0 December, 2014

7. Solenoid Controlled, Pilot Operated Valve Used With Double-acting Cylinders

PT

AB

9512

OPERATION

Neutral (HOLD): When both solenoids are de-energized, uid from pump circulates at free ow from the pres-

sure port “P” to tank “T”. Both cylinder ports are blocked.

Solenoid “A” Energized: Pressure to cylinder port “A”. Cylinder port “B” to tank.

Solenoid “B” Energized: Pressure to cylinder port “B”. Cylinder port “A” to tank.

NOTE

Pressure holds without loss when shifted from cylinder port to the neutral (HOLD) position.

Single-acting, Spring Return Cylinder: Either uid port “A” or “B” must be plugged with a steel plug on the

valve. With port “B” plugged, the sequence of operation is as follows: When solenoid is energized to position

“A”, uid port “A” becomes pressurized. When solenoid is energized to position “B”, uid port “A” becomes the

return port.

Double-acting Cylinders: When operating double-acting cylinders, uid port “A” can be connected to either

the advance or return port of the cylinder and uid port “B” will be connected to the remaining port. Sequence

of operation is as follows: When solenoid is energized to position “A”, port “A” becomes pressurized and ex-

tends the cylinder and uid port “B” becomes the return port. When solenoid “B” is energized, the opposite of

step 1 happens.

The application in Figure 5 represents a typical set-up using a control valve and multiple double-acting cylin-

ders (one double-acting cylinder may be used). Interow will occur.

If a different set-up or cylinder is being considered, contact your nearest Power Team facility.

ADJUSTING THE PRESSURE REGULATING CONTROLS

The pressure regulating valve and pressure switch are shown in Figure 6. The pressure regulating valve can

be adjusted to bypass uid at a given pressure setting while the pump continues to run. The pressure switch

can be adjusted to stop the pump at a given pressure setting. To ensure accuracy and low pressure differential

(approx. 300 PSI [21 BAR]) throughout the pressure range (1,000 to 10,000 PSI [70 to 700 BAR] depending on

the pump model), the pressure switch should be used with the pressure regulating valve. The pressure switch

must be set at a pressure lower than the pressure regulating valve to work properly.

1. Adjusting The Pressure Regulating Valve

NOTE

For easy adjustment of the pressure regulating valve, always adjust the pressure by increasing to the

desired pressure setting.

A. Loosen the locknut (B) on the pressure regulating valve, and back the adjusting screw or knob (A) out

a few turns by turning it in a counterclockwise (CCW) direction. This will decrease the setting to a lower

than desired pressure.

B. The pump must be completely connected electrically and hydraulically. Start the pump.

C. Slowly turn the adjusting screw or knob (A) in a clockwise (CW) direction. This gradually increases the

pressure setting. When the desired pressure is reached, lock the adjusting screw (A) in position by

tightening the locknut (B). Shut off the pump.

IMPORTANT

• The pressure range is from 1,000 to 10,000 PSI (70 to 700 BAR) depending on the pump model.

• The pressure switch must be set at a higher pressure than working range to prevent shut down dur-

ing adjustment.

2. Adjusting The Pressure Switch

Generally, the pressure switch should be used with the pressure regulating valve. A pressure switch can be

used alone for operating electrical devices such as motors, solenoids, relays, etc., which are located else-

where in the circuit. Refer to Figure 7.

Rev. 0 December, 2014

Pressure

Switch

Figure 7

A. Loosen the locknut (B) on the pressure switch, and turn adjusting screw (A) in a clockwise (CW) direc-

tion. This increases the pressure setting to a higher than desired pressure.

B. Adjust the pressure regulating valve to the desired pressure setting. Refer to the section titled “Adjust-

ing The Pressure Regulating Valve”.

C. With the pump running and bypassing uid at the desired pressure, slowly turn the pressure switch

adjusting screw (A) in a counterclockwise (CCW) direction, decreasing the pressure switch setting until

the pump motor shuts off. Then lock the adjusting screw (A) in position by tightening the locknut (B).

D. Release pressure. Run the pump to check the pressure setting and cut-out of the motor. It may be nec-

essary to make a second adjustment.

NOTE

When the pressure switch setting is reached, the motor will shut off. However, the inertia of the motor

continuestodeliveruidforabriefperiod.Thepressureregulatingvalvebypassesthissurplushy-

draulicuid,preventingitfromgoingintothesystem.Asaresult,thepressuredifferentialcanbeheld

PREVENTIVE MAINTENANCE

WARNING

To help prevent personal injury,

• Disconnect the pump from the power supply before performing maintenance or repair

procedures.

• Repairsandmaintenancearetobeperformedinadust-freeareabyaqualiedtechni-

cian.

1. Checking The Hydraulic Fluid and Filling The Reservoir

The hydraulic uid level should be checked after initial set-up and after each ten hours of use.

A. Thoroughly clean the area around the ller cap with a clean cloth to prevent contamination of the hy-

draulic uid.

B. Cylinder(s) must be fully retracted and the power supply disconnected.

C. Remove the ller cap and insert a clean funnel with lter. Fill to proper level as instructed in “Filling The

Pump Reservoir” under Set-up Instructions.

D. Replace ller cap.

over cleanliness and care given the pump. Three hundred hours of use under general shop conditions

is considered a standard change interval. Rain, clean, and rell the reservoir with a high grade hydrau-

lic uid.
