INSTALLATION OPERATION AND MAINTENANCE INSTRUCTIONS
VERTICAL TURBINE PUMP - NVT SERIES
Ref. No. NVT-IOM/2020/V.01
»
Make sure fuel tank is ¾ full.
»
Check the diesel and jockey pump controllers and verify the selector switch is in the automatic position.
»
Check batteries to ensure that the voltage readings on them are normal.
»
Check batteries and verify that the charging current readings on them are normal.
»
Check oil filter, fuel filter and air filter conditions.
»
Ensure proper clean exhaust vent.
»
Check battery terminals to ensure that they are free of corrosion and connections are tight.
»
Check and make sure cooling water level is normal in diesel engine if radiator type.
»
If provided, check to ensure that the water jacket heater is operating (Heat exchanger diesel engine).
»
Check to ensure that the antifreeze in cooling system heat exchanger is adequate.
»
Check all hoses, fuel lines, and cooling line connections for any leakage and to ensure they are in a good
condition.

. Fire pump Inspection,Testing and Maintenance Schedule.
7.3. Electric Fire Pump – Test Procedure
»
Ensure that the discharge line is closed in the system
»
After completion of all inspection procedures, start the pump automatically by slowly dropping the pressure
in the controller sensing line. After starting, the pump should be run at least
10
minutes.
»
Record the pressure at which the pump automatically started.
»
Record the pump suction and discharge pressures.
»
Check the pump packing glands to ensure proper tightness and adequate lubrication (should be slow drips –
approximately
1
drop per second – adjust glands if necessary with pump off).
»
If horizontal motor then check and verify that the right angle gear drive and drive shaft is operating smoothly
without any abnormal vibration or noise.
»
Check the pump stuffing box packing gland and discharge head for any signs of overheating (stuffing box
should be warm to the touch – discharge head should be cool to the touch).
»
Check for any unusual noise or vibration from pump or motor.
»
Verify operation of all supervisory signals (i.e., pump running, loss of power, phase reversal, etc.).
»
Verify all the valves are back to the normal position.
»
Verify that pump is left in the automatic start mode upon completion of each test.
7.4. Diesel Fire Pump – Test Procedure
»
Ensure that the discharge line is closed in the system
»
After completing all inspection procedures, start the pump by slowly dropping the pressure in the controller
sensing line. The pump should be run a minimum of
30
minutes.
»
Record the pressure at which the pump automatically started.
7.3. Jockey Pump – Testing
»
Verify start and stop settings on the pressure maintenance pump (jockey pump) by dropping the pressure in
the sensing line.
