Fire Pump

Well maintained automatic fire pump systems are very reliable and play a key role in reducing death rates and property damage during fire emergencies. Regular inspection and testing goes a long way toward making sure your fire pump offers you full fire protection. If you need your Hawaiian fire pump inspected, call National Fire Protection today.

Fire Pump Inspection

Like all other equipment, fire pumps deteriorate over time. Fire pumps are also vulnerable to external factors such as corrosive environments, tampering, accidental damage and careless use. Since they are used so infrequently, fire pumps must also be routinely inspected to determine their condition, operability and need for routine maintenance. For all your fire pump inspection needs, call National Fire Protection.

Our services include, but are not limited to:

Coupling Alignment

One of the most crucial steps of fire pump inspection is making sure your fire pump's couplings are aligned properly. There are many factors that can affect alignment, including thermal expansion and equipment maintenance. Couplings that are misaligned are far more likely to fail and could cause disruption of service.

Circulation Relief Valves

Circulation relief valves are usually mounted on the neck of the discharge flange, and prevent the fire pump from overheating when the pump is operating at shutoff condition. The valve should be inspected weekly and should discharge to a drain. Visual inspection of the fire pump is critical because if the valve fails to operate, the fire pump could overheat at a time when it is needed most.

Bypass Loops

Bypass loops are important because they provide sufficient suction pressure for your fire pump system to work even without the pump. While they will not be able to give you the full 100 psi, they still allow for a good level of protection even if the pump is not operating at full capacity.

Fire Pump Testing

It is highly recommended that all fire pumps undergo weekly testing at shutoff conditions. Electric fire pump systems should be tested for 10 minutes, while diesel fire pump systems should be tested for 30 minutes. Annual testing is conducted at minimum, rated, and peak load to ensure that the fire pumps will work optimally under all of these conditions. Every three years, demand must be placed on the suction supply to test the hose streams and flow meter systems.

Fire Pump Maintenance

Fire pumps must undergo regular preventative maintenance to ensure that they maintain their effectiveness. One of the most common maintenance measures is proper bearing lubrication. As a general rule, an ounce of grease should be added to the bearings every 3 – 6 months, and care should be taken to not add too much grease.
