Items such as the packing and gland halves require replacement if the fire pump isn’t run for a long time. Replacing fire pump packing and gland halves can cost between $2,000-$3,000.
How do I choose a fire sprinkler pump?
How to select a fire pump:
- Gather fire water-supply information.
- Calculate required flow.
- Calculate required pressure.
- Calculate pressure boost required.
- Select pump where flow demand is between 100% and 150% of rated flow.
- Select pump with performance curve where pressure boost is sufficient at flow demand.
What is the best pump for fire fighting?
In our experience, the most popular fire fighting models are the:
- Water Master Honda Fire Fighting 1.5″ Water Pump – popular for home owners on small to medium rural blocks.
- Crommelins Fire Fighting 1.5″ Water Pump with Trolley – also a very popular domestic model (see demonstration video at the top of this article).
What are the three major types of fire pumps?
Customary types of fire pumps include the horizontal split case, vertical split case, vertical in-line, and vertical turbine. The most common type of fire pump is the horizontal split case. These pumps are most economical for higher flow applications and are easily accessible for repairs or maintenance.
How much do fire sprinkler systems cost?
The average sprinkler system (pump NOT included) will run you anywhere between $1.50 – 3 for a new building. If you’re retrofitting an old building, expect to pay upwards of $3 – 10 per square foot – not bad, all things considered!
What pressure should I pump my sprinklers at?
Water pressure is measured in pounds per square inch – also called psi. The average water pressure for most homes and businesses is between 30 psi and 50 psi; most sprinkler systems are designed to use pressures of around 30 psi.
What size pump do I need for my sprinkler system?
End users should determine the amount of water to be applied during the peak period by multiplying the size of the field by the amount of water in inches that must be applied. The result is then converted to gallons per minute (gpm), and this number determines the size of the pump.
What is the difference between a transfer pump and a fire fighting pump?
A transfer pump is only used when moving water from one place to another; for instance, from a water tank to a garden pond. It has high flow and low pressure. Firefighters are high flow and high pressure, good for transferring a lot of water quickly without using any power.
What is PSI in fire fighting?
PSI stands for pressure per square inch, and GPM stands for gallons per minute. Both of these are vital in helping you choose what kind of firefighting pump you need, and it is very important to know about the PSI and GPM before buying any pump, regardless of the use.
How do you size a fire sprinkler pump?
For example, if you have a 40,000-square-foot building that is all ordinary group 1, the calculation would be 1,500 x 0.15 (density) = 225 + 250 (hose demand) = 475 gpm total for the fire pump. If the structure has multiple hazards, the hazard with the highest gpm calculation dictates the pump size.
What is a high pressure water pump for fire sprinklers?
High pressure water pumps designed to increase the firefighting capacity by boosting the water pressure of fire sprinkler tanks. Service and maintenance packages available for all types of pumps throughout the UK. SEND YOUR ENQUIRY NOW! CONTACT OUR TECHNICAL TEAM TODAY!

How many fire pumps are there in a fire system?
In a fire installation there can be one or more fire pumps put into operation as a duty assist (50 %) – and standby pumps. The fire pump delivers the water via the pipe system to the fire sprinklers to suppress the fire. The number of fire-pumps installed depends on the occupancy hazard (LH, OH or HH) and specific fire installation standard.
How does a fire pump work?
Fire pumps are part of an applications water supply and are powered by electricity, diesel or steam. They activate when the pressure in the fire sprinkler systems falls beneath a certain level and provide water flow at a very high pressure to the sprinkler system, which is then disposed onto the fire.
