Connect The Cooling-Water Pipelines; Fit The Drive/Transmission (Bareshaft Hv8000 Pumps Only) - Edwards HV8000 VF Instruction Manual

3.6

Connect the cooling-water pipelines

Note: Refer to Section 2.4
requirements specified.
Connect your cooling-water pipelines as follows:
1. Refer to Figure 1 detail D. Connect the cooling-water supply pipeline to the cooling-water inlet (20).
2. Connect the cooling-water return pipeline to the cooling-water outlet (19).
Refer to Section 2.4 for the minimum cooling-water flow rate required. Do not allow the cooling-water supply
pressure to go above the maximum pressure stated in
3.7

Fit the drive/transmission (bareshaft HV8000 pumps only)

Ensure that the drive/transmission is suitable for use with your pump/system.
You must fit suitable guards to protect people from rotating/moving parts.
Your drive and transmission system design must ensure that the maximum pump rotational speeds specified in
Section 2.3 cannot be exceeded, otherwise the pump will be damaged, or may not operate correctly.
If you are using one of the motor mounting kits, then continue at Section 3.7.1
You must use a suitable coupling or a belt drive and transmission system to connect your drive to bareshaft HV8000
pumps.
Your drive and transmission system design must ensure that the maximum radial loadings on the pump drive shaft
are less than those specified in
a diameter larger than the minimum diameter specified in
Connect the components of the drive and transmission system to the pump drive shaft (see
described in the manufacturer's instructions supplied with the components.
After you have connected the drive/transmission, continue at
of the HV8000 pump.
