3.19.4 Checklist – Initial start-up
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 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.
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 accidental contact re in place.
c Monitoring system is operational.
3.19.5 Start-up
When the pump is to be put into service the following checklist and procedure must be observed:
c Pump is filled with liquid.
c Pump is sufficiently preheated.
c Suction and discharge valves are fully open.
c Start the pump for a short while and check the direction of rotation of the motor and that the
magnetic coupling is not slipping.
c Start the pump and check suction of liquid (suction pressure).
c RPM of the pump is checked.
c Discharge pipe and seal are checked for leaks.
c Proper operation of the pump is verified.
