Functional Description 3 Product Description

3.4 Functional Description

Functional Description The shaft (Pos. 11) transfers the drive torque to the star-shaped cylinder b lock

(Pos. 7), free of any axial forces, via a crossdisc coupling (Pos. 10). The cylinder block is hydrostatically supported on the control journal (Pos. 6). The radial pistons (Pos. 5) in the cylinder block run against the stroke ring (Pos. 3) through hydrostatically balanced slipper pads (Pos. 4). The pistons and slipper pads are joined by ball and socket joints and locking rings. The slipper pads are guided in the stroke ring by two retaining rings (Pos. 2) and, when running, are held against the stroke ring by centrifugal force and oil pressure. As the cylinder block rotates, the pistons reciprocate due to the eccentric positioning of the stroke ring, the piston stro ke being twice the eccentricity. The eccentric position of the stroke ring is controlled by two diametrically opposed control pistons (Pos. 1, Pos. 8) and the pressure compensator (Pos. 9). The oil flow to and from the pump passes thro ugh th e pump p orts and in to and out of the pistons through the porting in the control journal. The bearing supporting the drive shaft is only subjected to external forces. The compensator setting limits the system pressure and adjusts the pump flow between zero and full flow to maintain the set pressure.

- Use suitable cleaning rags.

- Do not allow the cleaning agent to penetrate into the hydraulic circulation loop.

3. Ensure that the coupling hub is tightened to the drive shaft or that the drive shaft is lubricated continuously to pre vent wear from vibration.

4. Transport the pump to the mounting location.

5. Mount the coupling to the drive according to the information provided by

the coupling manufacturer.

Only bolt the pump down after the coupling has been mounted correctly.

6. Faste n th e pu m p with the couplin g at the mo u nt ing loca tio n. Tigh te n th e mounting screws with the adequate tighte n ing tor qu e crosswise. Ö Chap. "12.2 Tightening Torque", Page 63

7. For bell housing mounting: Check the coupling's axial clearance as per the information provided by the coupling manufacturer.

8. For mounting a flange: Align the pump supports in the direction of the drive.

9. For elastic couplings: After completing the mounting, check the drive to make sure it does not vibrate.

6.3 Planning Lines

In order to minimize the development of noise from the transmission of structure-borne noise, observe th e follo win g:

• Use hoses instead of pipes.

• Secure pipes with elastic clamps.

Suction Line

WARNING Damage to property from cavitation!

Lack of pressure in the suction line may lead to the formation of air bubbles in the operating fluid and as a result may lead to severe damage to the pump.

• Configure the layout of the suction lines so that the inlet pressure cannot be any lower than the minimum of

0.8 bar absolute at the suction port.

• Ensure that the operating fluid has the correct viscosity.

Planning Lines

• Short suction lines with wide inside diameters are needed to ensure that the noise output is low.

• Suction speed < 1 m/sec.

Connecting Pipes 6 Mounting

• Avoid sharp angles and screwed pipe joints (danger of air intake and dispersion, high flow resistance). Use curved pipes or hoses instead.

• Maintain the minimum inlet pressure.

• Only reduce the length of the suction line at the pump entry.

• If a suction filter (min. 0.15 mm mesh aperture) or a shut-off valve is used, install the devices below the fluid level.

Pressure Line

• Ensure sufficient stability.

• Inspect the tightening torques of the screws.

Drain Line

• Install the drain line so that the pump housing is always completely filled with pressure fluid (use the upper connection).

• It should lead directly into the tank separated from the other return lines.

• The end of the line must be below the fluid line in the tank, even at the lowest fluid level.

• The distance from the suction line should be as large as possible. Do not place a filter, cooler or non-return valve in the drain line. Max. length 3 m.

• Pressure at the drain line max. 2 bar absolute (1 bar above atmosphere).

• The recommended outside diameter of the pipe used as a drain line (lightweight version): Ö Tab. 3, Page 27

Connecting Pipes

6.4 Connecting Pipes

For the pump, the connections do not depend on the direction of the rotation.

Procedure:

For securing the control and leak oil port and the suction and pressure flange, the appropriate screw connections must be used.

1. Remove the end caps from each connection.

2. Clean the sealing surfaces and the lines.

3. Connect the lines in accordance with the block diagram (suction line A, pressure line B). Ö Chap. "12.2 Tightening Torque", Page 63

4. For pumps with load sensing compensator with p-T control notch

- The compensator's tank line may not be combined with the pump's leak oil line.

5. For multiple pump arrangements, which are equipped with the "load sensing compensator with p-T control notch", in the event that a circular flow is required:

- Only connect the tank line to the tank at the compensator of the first pump to activate the p-T control notch.

- Close off the compensators' t-connections for the add-on pumps.
