We are known for our wonderful customer service, our expertise, and our reliability.

Fulfillment of both these conditions is mandatory if a fire fighting pump is to be in compliance with NFPA 20 requirements.Rated capacities for these pumps can be seen at the table below:Each of the above listed pump rated capacities corresponds to a minimum size of suction and discharge nozzle, relief valve and flow metering device. The working of these pumps can be related to gear pumps, apart from the lobes which do not approach into contact by each other.

These pumps are not suitable for driving solids as well as harsh liquids.Peristaltic pumps are also named as tube pumps, peristaltic pumps.

These pumps are frequently used in Scale Atomic Clock by National Institute of Standards &Technology

Types. This mode of pump utilizes no filling container to cover the shaft however in its place uses a throttle bushing. In fact, they were the first pump type to be utilized for mobile fire truck applications, long before centrifugal pump designs were used for pumping fire water.

A reduced-voltage start also should be considered when connecting to a generator to potentially reduce the size of the generator. The pump provides water flow at a higher pressure to the sprinkler system risers and hose standpipes. Centrifugal Pumps.

Insurance companies also may have unique requirements that go above and beyond the code. These pumps are capable of pumping on high forces & surpass at pumping high thickness fluids efficiently.A gear pump doesn’t contain any valves to cause losses like friction & also high impeller velocities. Types of pumps used for fire service include: end suction, horizontal split case, vertical split case, vertical inline and vertical turbines.

In many buildings, the fire sprinklers serving a commercial building might not be able to control or extinguish the fires that start without adequate amounts of water or water pressure.

In a fully sprinklered structure with standpipes, NFPA 14 (2010): Standard for the Installation of Standpipes and Hose Systems says that the first standpipe requires 500 gpm and each additional standpipe requires 250 gpm, up to a maximum of 1,000 gpm.For example, a building with two standpipes would require a 750-gpm pump (500 gpm for the first standpipe and 250 for the second), and a building with five standpipes would require a 1,000-gpm pump because that is the maximum allowed by NFPA 14. Thus, if the water supply is located below the suction inlet to the fire pump, you may have to utilize a vertical turbine fire pump in lieu of the other types of pumps available.The last job parameter you need in order to size the fire pump is the required flow for the systems the pump will be serving (sprinklers, standpipes, or other). In addition, the shut off head shall not exceed 140% of rated head. This pump type has more material options than other types. If not, request a new test using more hydrants or plot a water supply curve (see Figure 1).If you are using a private water supply, lake, or ground-level storage tank, you must remember that you are not permitted to use a suction lift with a fire pump. This steam is then circulated through steam pipes...Advertise directly with us. For more information on how we can help your residential or commercial property, or give us a call at (800) 553-3405.

For standpipe systems, this flow is related to the type and size of the structure the pump is protecting.

Types of pumps used for fire service include: horizontal split case, vertical split case, vertical inline, vertical turbine, and end suction. One major benefit of this fire pump is that it protects the motor from flooding simply due to how it is built.Unlike the split-case fire pumps, the vertical in-line fire pump is smaller. Every stage is fundamentally a divide pump.All the phases are in a similar shelter & mounted on a similar shaft.

We have been protecting people and properties from fire damage since 1947—and our experience shows in our excellent work! The three most widely used pumps are horizontal split case, inline and vertical turbine.Horizontal split case pumps are also called double-suction fire pumps, because the water pathways direct water to both sides of the impeller.

The applications of these pipes mainly include in different impellers like closed, contra-block, vortex, multi-stage, single channel, cutter, otherwise grinder pumps. This is almost never the case, but different pumps and speeds affect the churn pressure, so you should always look at a curve to determine the shutoff pressure. Here are some types of fire pumps you should work with your fire protection partner to evaluate and install.Horizontal Split Cases are the fire pumps you will see most often.
