Pumps and Motors

Gear Pump

New Eaton AEG Series global pump, which is a pressure-balanced

floating bushing design in a high strength extruded aluminium body.

End cap and mounting flange are cast iron. 12 gear design with high

efficiency profile is employed for low pressure ripple, and thus for quite

operation. The pump uses temperature polymer seals and backups.

These features provide reliable performance over a long time period

with reduced vibration and noise levels.

Vane Pump

Eaton-Vickers V10 and V20 Series, which are well-proven in many

applications. The pressure-balanced design theoretically provides

infinite shaft bearing life, and high performance will be maintained

for a long time for the compensation principle against the wear of

vane tips. The pressure plate, as well as low vane tip/ring loading

optimizes pump performance in quiet operation.

Pumps are repairable with the availability of cartridge and other

spare parts.

Piston Pump

Eaton-Vickers PVQ and 420 Series pumps are used depending on

displacement sizes, which are compact, high efficiency axial piston

type units with high response controls.

With the use of piston pumps, system efficiency will increase for

flow match to your flow requirements (plain pressure compensator

control, which is the standard unless specified), or optional power

match to your flow and pressure requirements (loadsensing control),

reducing system running costs and saving power and energy.

Plain compensator control pressure can be adjusted externally by

a remote control relief valve installed in the base manifold of the

EPAK unit.

Electric Motors

Standard 3-phase motors are cast iron framed squirrel cage induction type 4 pole

electric motors.

Supply : 415V50Hz, 3-phase

Insulation : Class 'F' with Class 'B' temperature rise

Enclosure : TEFC

IP Rating : IP55 (Consult Eaton for higher IP rating requirements)

Standrad (up to 4kW) single phase motors are cast iron framed.

Supply : 240VAC50Hz, Single-phase

Insulation : Class 'F' with Class 'B' temperature rise

Enclosure : TEFC IC0411

IP Rating : IP44

Standard air-cooling type optional oil coolers are available with three(3) coolingcapacities. They are available with either 415V50Hz 3-phase electric motor, or240V50Hz single-phase motor to your choice. --- specify your requirement whenordering.

Loadsensing control pump and manifold

An optional manifold where the loadsensing line is connected to A and B ports ofeach station via check valves, and the loadsensing line is connected to aloadsensing piston pump used in the EPAK. The pump control has the bleed downorifice to avoid pressure trap in the loadsense line. See Page 14 for details.

Typical cooler installation as per below. --- request a drawing for further details.

Station Manifolds

Optional station manifolds with CETOP-3/5 valve interfaces are available, which will be installed vertically

onto the base manifold of the EPAK.Standard manifolds are of aluminium, and steel manifolds are

available on request. See drawings in the previous pages for valve interface and port orientations.

Valving onto the manifold will require proper engineering, based on hydraulic circuit requirements, pressure

and flow ratings, pressure drop considerations, etc. Consult Eaton if required.

* Dimension(b) : port-to-port dimension for non-single station manifilds.

(Note)

Drawing left shows A and B port designation for CETOP-3 blocks.

With CETOP-5 blocks, A and B ports are replaced. --- i.e. valve interface

side ports are B ports, and not A ports. This is common for manifolds

below with loadsensing, or for series circuit.

Loadsensing Manifolds (Aluminium - Maximum Pressure 210 bar)

Manifold dimensions are identical to the parallel circuit block above without loadsensing line.

See above note for A and B port locations with CETOP-5 manifolds.

Series Circuit

Manifold dimensions are identical to the parallel circuit blocks above.

The valve in a station at the highest position is always the first valve in the series circuit.

Max. continuous 430 cSt, Max. start-up 2100 cSt, Min. 10 cSt

Cleanliness * Contamination level of 20/18/13 (Eaton), or 18/13 (ISO) as minimum recommendation

* These vary with types of components used in your system and operating conditions, including pump selection.

See Eaton technical publication for more information.

Installation

1. Select a well ventilated area and make sure floor is level prior to bolting the reservoir down.

2. Make all electrical connections in accordance with the applicable standards, and Occupational

Safety and Health Act (OSHA).

3. Ensure that the entire hydraulic system is in good conditions and ready for start-up.

4. Fill the reservoir through the filler breather with pre-filtered quality hydraulic oil (See recommendations).

5. Re-check oil level during initial cycles. Fill to top of the fluid level gauge on the reservoir but not overfill.

Start-Up

1. A care must be taken for safety issues as top priority in the system start-up process.

2. Jog the electric motor to confirm rotation direction. Proper rotation is CW facing fan end of the motor.

Polyphase motors are bi-directional and proper rotation can be reversed by swapping two power leads.

3. At start-up, start and stop motor several times to allow the pump to prime before full flow begins.

4. The relief valve on this unit is factory set at the maximum pressure for the electric motor power used,

unless specified otherwise. Refer to the specification section prior to adjusting the relief valve to make

sure that your operating conditions are within the specified limits of the motor being used.

It will be generally recommended that the relief valve be approximately 7 bar higher than operating

pressure required. To adjust the setting, refer to the following general steps.

4-1. Turn the unit on.

4-2. Block manifold outlet, or move cylinder(s) to full stroke so oil is going over relief valve.

4-3. Check pressure gauge.

4-4. Loosen lock nut on the relief valve, and turn the screw adjustment with allen key. CW rotation

increases pressure, and CCW to decrease pressure setting.

4-5. When a desire pressure is reached on the gauge, tighten lock nut, and re-check the pressure.

5. System pressure should be set as low as possible to prevent unnecessary fluid heating : in certain

applications, this setting may be from 3 to 15 bar above necessary static pressures to overcome

dynamic pressure drop, or to achieve proper acceleration.

6, Bleed all air from the system to prevent erratic operation.

7. In the first few hours of operation, contaminant levels are generally high. Carefully check the filter

indicator especially during initial run.

8. In most industrial applications, 65° C will be considered as maximum fluid temperature. At higher

temperatures, difficulty is often experienced in maintaining reliable and consistent hydraulic control,

component service life will be reduced, hydraulic fluid deteriorates and a potential danger to

operation personnel may result.

9. Pressure compensator with a loadsensing pump is factory set at the maximum achievable pressure

with the electric motor used. The relief valve does not re-adjust the setting of the compensator,

18 and it works to limit the loadsense line pressure within the pump compensator setting.
