6 Mounting Planning Lines

Procedure:

1. Mount the specified half of the coupling to the pump's drive shaft as per

the information provided by the coupling manufacturer.

2. Make sure that the connection and mounting surfaces are clean.

- If not, clean the connection and mounting surfaces using suitable

cleaning agents.

- 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 prevent 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.

6. Fasten the pump with the coupling at the mounting location. Tighten the

mounting screws with the adequate tightening torque crosswise.

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

Planning Lines

Suction Line

• Short suction lines with wide inside diameters are needed to ensure that

the noise output is low.

• Suction speed < 1 m/sec.

The threaded bore on the pump's drive shaft can be used to mount

the coupling.

Only bolt the pump down after the coupling has been mounted

correctly.

In order to minimize the development of noise from the transmission of

structure-borne noise, observe the following:

• Use hoses instead of pipes.

• Secure pipes with elastic clamps.

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.
