What is capacity of fire pump?
up to 2280 l/rein capacity and 100 mm for bigger pumps up to 4500 l/rein. For extra ordinary big pumps, the thickness may go up to 150 mm.
How do you size a fire jockey pump?
“The pump manufacturer, Armstrong pumps, recommends, as a rule of thumb, to size the jockey for about 1 % of the rated flow of the main fire water pump. Also they recommend that jockey to be sized with 10 psi (0.7 bar) higher pressure than the system design pressure of the firewater ring.”
How do I choose a fire 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.

How many types fire pump?
Fire-fighting pumps are usually single-stage volute casing pumps, double-suction radial flow pumps (see Double-suction pump), ring-section pumps, submersible borehole pumps or deep-well turbine pumps. They extract fire-fighting water from tanks, fire water ponds, rivers or lakes.
How do you build a pump capacity?
The steps to follow to select a centrifugal pump are:
- Determine the flow rate. To size and select a centrifugal pump, first determine the flow rate.
- Determine the static head.
- Determine the friction head.
- Calculate the total head.
- Select the pump.
What are the types of fire pumps?
Types of Fire Pumps
- Horizontal Split Case. The horizontal split case fire pump is the most common type for commercial buildings.
- Vertical Split Case. The vertical split case fire pump is similar to the horizontal split case pump, but they take up less space because they’re vertical.
- Vertical In-Line.
- Vertical Turbine.
What is the maximum allowed suction head for the fire pump?
The maximum actual suction lift for a centrifugal pump is approximately 15 ft when pumping water from an open air tank.
What is the maximum allowed suction head for fire pumps?
How do Jockey pumps work?
Sprinkler systems consist of pipes with pressurized water in them and heads that are designed to open when they reach a certain temperature. When the heads open, the water pressure in the pipes drops, since water is flowing out of them. The jockey pump senses this, and then fills them back up to normal pressure.
What are the three major types of fire pumps?
Types of fire pumps include: horizontal split case, vertical split case, vertical in-line, vertical turbine, and end suction. These fire pumps may be powered by an electric motor or diesel engine and on rare occasion powered by a steam turbine.
How to calculate fire water pump capacity Part 1?
Fire water pump capacity calculation begins with fire zones determination. The whole pictures of fire water pump capacity calculation is expressed in figure below. To determine fire water pump capacity, we can say we determine fire water demand.
How to calculate fire pump pressure in Maryland?
Pressure requirements for your fire pump can be calculated via two different methods: the “standpipe method” or sprinkler area calculations. Click here for more information about fire pump inspection in Maryland »
How to calculate jockey pump capacity in fire fighting system?
Based on NFPA 20 year of 1999 Standard for the Installation of Stationary Pumps for Fire Protection , pressure maintenance pumps (jockey pumps) shall have rated capacities not less than any normal leakage rate. The pump shall have discharge pressure sufficient to maintain the desired fire protection system pressure.
