5. Before dismantling
General information about BMS hs and BMS hp
The work site must be clean, free of salt or brine water and iron
filings. Clean the workplace with flushing water, if it is necessary.
1. If the pump is to be repaired at a service workshop, do the
following:
2. Check that the pump has not been damaged during
transportation.
3. Identify the type designation. See the pump nameplate.
4. If the repair is to be done on site before dismantling the pump,
check the installation:
– wiring connections (power supply and signals)
– hydraulic connections
– inlet and outlet pressure and flowmeter value(s), if possible
– protection: pressure switches, flow switches and motor
protection etc.
5. Compare the motor voltage and frequency details on the
motor and frequency converter nameplates with the power
supply available.
– Read and note down the trip and failure log of the frequency
converter.
5.1 Dismantling pump and motor
1. Remove the Victaulic clamp at the inlet-and outlet.
2. Remove the service connector, if it is installed.
