After thorough servicing or when the pump is to be put into service for the first time
(initial start-up) the following checklist must be observed:
Supply and discharge line
c
Suction and discharge pipes are cleaned.
c
Suction and discharge pipes are checked for leaks.
c
Suction pipe is protected properly to prevent the ingress of foreign bodies.
Characteristics
c
The characteristics of the pump unit and safety relief valve to be checked
(pumptype – see name plate, RPM, working pressure, effective power, working
temperature, direction of rotation, NPSHr etc.).
Electrical installation
c
Electrical installation complies with local regulations
c
Motor voltage corresponds with mains voltage. Check terminal board.
c
Make sure that the starting torque is sufficiently high (no star/delta starting will be used).
c
Motor protection is adjusted properly.
c
Direction of motor rotation corresponds with direction of pump rotation.
c
Motor rotation (detached from unit) is checked.
Safety relief valve
c
Safety relief valve (on pump or in piping) is installed
c
Safety relief valve is positioned correctly. Flow direction of safety relief valve
corresponds with suction and discharge lines.
c
Make sure a double safety relief valve is installed when the pump has to operate in two
directions.
c
The set pressure of the safety relief valve is checked (see nameplate).
Jackets
c
Jackets are installed.
c
Maximum pressure and temperature of the heating/cooling media have been checked.
c
The appropriate heating media or coolant is installed and connected.
c
The installation complies with the safety standards.
Shaft sealing
c
Pressure, temperature, nature and connections of flush or quench media has been checked.
Drive
c
Alignment of pump, motor, gearbox etc. is checked.
Protection
c
All guards and safety devices (coupling, rotating parts, excessive temperature) are in place
and operative.
c
In case of pumps that may reach working temperatures of 60°C or more, ensure sufficient safety
guards against occasional touching are in place.
