Installation, Operation and Maintenance
Normal Operation:
Monitor the following during running cycles:
A.
Unit vibration or noise.
B.
Driver lubrication levels and flow.
C. Seal box leakage.
D. Water lubrication system.
Check the following before normal start-up:
A.
Driver lubrication levels and flow.
B.
General condition of all equipment.
C. Water lubrication system.
Shutdown:
Pump stations are usually designed to have the pumps started and stopped automatically. Since this is a function
of station design, the operators should be familiar with the system operating parameters. The general procedure
to shut down the pump is as follows:
A.
Slowly close discharge valve.
B.
Disconnect the electrical power source.
Emergency Procedures:
Many installations are equipped with emergency shutoff switches near the pump location. These locations should be
plainly marked and readily accessible at all times.
The control panel (if used) may be equipped with an emergency start/stop button or switch.
The operator, or persons working around the equipment, should be familiar with locations of emergency
start-up and shutoff points.
Shutdown: Shut off the power at the nearest switch.
Seasonal Operating Instructions:
If the pump is located in an area that is subject to freezing temperatures and will not be operated enough to prevent
freezing, it should be drained to prevent damage to the casing caused by freezing. Steps should be taken to prevent
seal water lubrication system from freezing. Storage instructions must be adhered to.
