How do you maintain a fire pump?
Tips to Maintain Your Fire Pump
- Prevent parts inside the fire pump from locking in place by lubricating them and moving them around.
- Check the components inside your fire pump such as the pressure relief valve, the packing, and casing relief valve.
- Monitor your water pressure gauge.
How often should a fire pump be serviced?
Most fire pumps are either electric motor-driven, or diesel engine-driven, and the type and frequency of testing will vary depending on what you have in your building. For electric motor-driven fire pumps, we recommend at least running your equipment once a week for at least ten (10) minutes for a visual inspection.
How do you inspect a fire pump?
The following should be checked on all pump systems (electric & diesel)
- Record system suction and discharge pressure gauge readings.
- Check pump packing glands for slight discharge.
- Adjust gland nuts if necessary.
- Check for unusual noise or vibration.
- Check packing boxes, bearings, or pump casing for overheating.
What is a fire pump engine?
IRE PUMPS. Fire pumps are used to boost the water pressure in sprinkler and standpipe systems and to deliver the required amount of water (Figure 3.5). This is necessary when the system is fed by a non-pressurized water tank, or when the water supply feeding the system has inadequate pressure.
What is the pressure of jockey pump?
Jockey pumps are normally sized for 1% flow and a 10 to 20 PSI higher pressure of the main fire pump.
What is jockey pump in fire protection?
A jockey pump is a small pump connected to a fire sprinkler system and is intended to maintain pressure in a fire protection piping system to an artificially high level so that the operation of a single fire sprinkler will cause a pressure drop which will be sensed by the fire pump automatic controller, causing the …
How much do fire pumps cost?
Fire pumps “and their associated equipment” can “cost from $20,000 to more than $1,000,000 when suction tanks are required.” And since they are complex pieces of machinery that are vital to the operation of these systems, they have varied and highly detailed inspection requirements.
What are the requirements for a fire pump inspection?
Inspection, testing, and maintenance requirements are outlined in NFPA 25, standard for the inspection, testing, and maintenance of water-based fire protection systems. Below is an overview of the inspection and testing activities that should be completed on your pump.
Do you need maintenance on a fire pump?
Motors or diesel engines need maintenance; batteries need attention, etc. if we are to have confidence that a pump will start and operate as it was designed to. Well, we could go on, but I think the point is made that without recommended preventative maintenance, there is a greater risk that the “heart” of the sprinkler system will not pump.
Is there NFPA 20 for fire pump preventative maintenance?
This should not be confused with NFPA 20 Standard for the Installation of Stationary Pumps for Fire Protection, which does not cover preventative maintenance (some time ago NFPA consolidated all preventative maintenance into NFPA 25).
What does the weekly flow fire pump test do?
flow fire pump test, the weekly operational test is part of the preventive maintenance procedures recommended by the National Fire Protection Association (NFPA). The operational or “run” test helps assure that the pump will operate without mechanical difficulty and protect the facility if a fire should occur. WEEKLY TESTING
