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
(pump type – 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
Heating or cooling circuit has been checked for leakages.
c
Pressure, temperature, nature and connections of flush or quench media has been checked.
c
If a double mechanical seal mounted in back-to-back configuration, buffer media must be
pressurized prior to starting the pump.
c
When using the PR-version (reverted packing) for chocolate applications:
The packing is lightly tightened by hand at the factory. When pumping chocolate, the packing
needs to be tightened bit by bit at the initial start-up in order to achieve the utmost minimum of
leakage, just enough to lubricate the packing rings. Excessively leaking chocolate can overheat in
the packing, causing caramelisation, resulting in extra wear of the packing. Check if the external
grease supply is into service in order to lubricate the bush bearing at the start-up.
Drive
c
Alignment of pump, motor, gearbox etc. is checked.
