Do you know if your fire pump is fit to protect you, your employees and your building in the event of a fire? The fire pump is a critical piece of a building’s fire sprinkler system, delivering water to the sprinkler heads in the event of a fire. Regular fire pump inspection and testing is required in order to make sure your fire sprinkler system will be able to protect your building in the event of a fire. If your New Jersey, Delaware or Philadelphia building needs fire pump inspection, call Confires today.
Fire Pump Inspection
Like all other fire protection systems, fire pumps can lose their effectiveness if they are not properly maintained. Fire pumps are especially at risk: because they are so complex, fire pumps are especially vulnerable to things like corrosive environments, tampering, accidental damage and careless use. Since fire pumps are typically kept out of the way and (hopefully) are not used very often, fire pump inspection is extremely important to making sure the pumps will react the way they are supposed to. At Confires Fire Protection Services, our annual fire pump inspection services include:
One of the most crucial steps of fire pump inspection is making sure your fire pump’s driveshaft is aligned properly. There are many factors that can affect alignment, including thermal expansion and equipment maintenance. Packing glands are also inspected and adjusted as necessary to allow for the shaft to move freely.
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 are required because they provide water supply at street pressure when the pump is not functioning or being serviced. While they will not be able to give you full pressure, they still allow for water flow throughout the sprinkler system.
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. Annually, demand must be placed on the suction supply to test the hose streams and flow meter systems. Confires will also check the pump controller and current draw of the pump as well as motor rotation and RPM speed.
In addition to annual fire pump inspection, Confires Fire Protection Services also offers periodic fire pump testing. Weekly fire pump testing at shutoff conditions are recommended (see our blog post about how to exercise a fire pump), and annual fire pump testing at various load levels are a must.
Fire Pump Maintenance
Fire pumps must undergo regular preventative maintenance to ensure they maintain their effectiveness. Confires Fire Protection Services offers fire pump maintenance services, including lubrication and coupling alignment.
Routine fire pump inspection and maintenance are extremely important to ensuring your fire protection system will keep your building safe from fire at all times.
