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

cSuction and discharge pipes are cleaned.

cSuction and discharge pipes are checked for leaks.

cSuction pipe is protected properly to prevent the ingress of foreign bodies.

Characteristics

cThe 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

cElectrical installation complies with local regulations

cMotor voltage corresponds with mains voltage. Check terminal board.

cMake sure that the starting torque is sufficiently high (no star/delta starting will be used).

cMotor protection is adjusted properly.

cDirection of motor rotation corresponds with direction of pump rotation.

cMotor rotation (detached from unit) is checked.

Safety relief valve

cSafety relief valve (on pump or in piping) is installed

cSafety relief valve is positioned correctly. Flow direction of safety relief valve corresponds with suction and discharge lines.

cThe set pressure of the safety relief valve is checked (see nameplate).

Jackets

cJackets are installed.

cMaximum pressure and temperature of the heating/cooling media have been checked.

cThe appropriate heating media or coolant is installed and connected.

cThe installation complies with the safety standards.

Drive

cAlignment of pump, motor, gearbox etc. is checked.

Protection

cAll guards and safety devices (coupling, rotating parts, excessive temperature) are in place and operative.

cIn case of pumps that may reach working temperatures of 60°C or more, ensure sufficient safety guards against accidental contact re in place.

cMonitoring system is operational.

3.19.5Start-up

When the pump is to be put into service the following checklist and procedure must be observed:

cPump is filled with liquid.

cPump is sufficiently preheated.

cSuction and discharge valves are fully open.

cStart the pump for a short while and check the direction of rotation of the motor and that the magnetic coupling is not slipping.

cStart the pump and check suction of liquid (suction pressure).

cRPM of the pump is checked.

cDischarge pipe and seal are checked for leaks.

cProper operation of the pump is verified.
