Fire Water Pump is a specialty item that can be used to keep hoses pressurized during a fire. It works on the same principal as a regular water pump, but is designed to handle much higher pressures and flows. When it comes to choosing the right fire fighting pump for your property, it’s important to work with an expert who can help you evaluate your needs and source the best product.
Choosing the right pump depends on a number of factors, including the size of your property and the terrain. If you have steep slopes or tall trees, you may need to consider a bigger fire fighting pump to meet your needs. You can also choose from a variety of different sizes, depending on the amount of water you need to move.
In addition, you’ll need to choose between a diesel or petrol fire water pump. While both types can be effective, they have some important differences. Diesel and petrol fire pumps are able to produce high pressures at lower flow rates, which means they can spray water further and wider than electric fire pumps. However, the disadvantage of this is that they are less efficient.
Regardless of which type you choose, it’s essential to look for a fire pump that has the right certifications. For example, UL and FM are groups that provide listings and approvals for fire pumps. They have rigorous testing requirements that ensure the fire pump meets industry standards.
It’s also important to check the pump curve on the factory-certified test report. The pump curve will indicate when the power peaks and begins to drop. This is when the pump will be unable to supply the rated water demand and may be considered undersized by UL and FM.
The NFPA 25 Standard for Inspection, Testing and Maintenance of Water-Based Fire Protection Systems sets minimum codes for annual fire pump testing. These include requiring the pump to be tested at three points on the curve: no-flow (churn), 150% of the rated flow, and a maximum of 140 psi at the churn point. An excellent fire water pump should be able to perform all three of these tests with ease.
