A portable fire pump is a vital component of many water-based fire protection systems. They’re used to increase the pressure (measured in psi or bar) of a water source so that it can adequately feed a fire system. There are different types of fire pumps designed for varying needs, and it’s important to choose one that is compatible with the type of fire system being fed.
There are also several additional features to look for when selecting a portable fire pump. For example, consider whether you need a recoil or electric start option. Then, decide whether to opt for a 2-cycle or 4-cycle engine. Also, think about the maximum water pressure and flow rate you’ll need – this will impact how much power you’ll need from your pump.
In addition to being portable, these units are designed to be easy to maintain. They include a patented clamp impeller design that makes it easier to disassemble for impeller maintenance. They’re also highly fuel efficient and have a low-oil protection sensor to prevent overheating. This makes them a great choice for fire fighting, water transfer, boom spraying, and sheep jetting applications.
Most portable fire pumps are centrifugal-style fire pumps with diesel or gasoline engines. They are typically 4-cycle engines although some have 2-cycle options as well. Some have a self-primer while others require a manual hand priming or exhaust priming. Some are designed to work in a vertical position while others are designed to float and pump automatically when submerged in water.
When choosing a portable fire pump, it’s essential to follow the international standards for fire fighting equipment set by NFPA 20. This ensures that the equipment will perform properly in an emergency and protects lives and property.
The following fire pump classes are typically available:
These pumps can supply 60 gpm at 90 psi net pump pressure through a 2 1/2-inch discharge while taking suction through a 3 1/4-inch suction inlet. They are a great choice for draining cellars or other low areas, filling booster tanks on apparatus and can also be used to supply 60-gpm fog nozzles through 250 feet of 1 3/4-inch hose. They are limited to a size of 25 inches on each side and 150 pounds.
These pumps provide 125 gpm at 60 psi net pump pressure through s 2 1/2-inch discharge and suction inlets. They are a good choice for drainage of minor structural fires, to fill tankers and to drain cellars or other low areas. They can also be used to feed foam nozzles for interior fire fighting. This class is limited to a size of 25 inches on both sides and 150 pounds.
This class includes floating and backpack pumps. The pumps are capable of pumping and priming automatically when placed in a body of water. They can be powered by either a 4-cycle or 2-cycle engine and are typically equipped with rotary vane or crankcase pumps. They may also be designed with a positive displacement or turbine pump. portable fire pump
