3 Installation
3.1 Installation requirements
3.1.1. General requirements
The following requirements apply to all pumps:
• The pump is supplied as a bare shaft pump. To operate the pump, you must fit a motor, or connect
the pump to a drive with the characteristics set out in Section 2.
• You must use a suitable transmission system between the drive and the pump. The transmission
system can take the form of a coupling.
• If a sealing liquid supply system is not already fitted, you must install the pump in one of the system
configurations specified in Section 3.4.
• The pump may be noisy during operation (see Section 2.4). Where necessary, you must either
install the pump in an acoustic enclosure or ensure that people wear suitable protective equipment
(such as ear defenders) when they are close to the operating pump.
3.2 Safety
WARNING
If you use a water-based sealing liquid, harmful bacteria (such as
Legionella) could propagate inside the pump and sealing liquid supply
system. Take suitable precautions to inhibit bacterial growth and to ensure
that untreated bacteria-bearing mist is not discharged from the system.
WARNING
Obey the safety instructions listed below and take note of appropriate
precautions when you install the pump.
• A suitably trained and supervised technician must install the pump.
• Wear the appropriate safety-clothing when you come into contact with contaminated components.
• If your pumping system has already been used, vent and purge it before you start installation work.
• Ensure that the installation technician is familiar with the safety procedures which relate to the sealing/
seals flush liquid(s) and to the products handled by the pumping system.
• Disconnect the other components in the pumping system from the electrical supply/drive system so that
they cannot be operated accidentally.
