Question: What are the three major types of fire pumps?

There are three driver types outlined in NFPA 20: Standard for Installation of Stationary Pumps for Fire Protection: electrical motor, diesel engine and steam turbine systems. The motors/engines are what drive the impellers and spin the shafts that provide water to the systems.

How many types of fire pumps are there?

Common types of fire pumps used for fire service include: horizontal split case, vertical split case, vertical inline, vertical turbine, and end suction.

What are the different types of fire pumps How does each work?

Various types of fire pumps are used in fire protection systems. 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.

What is main fire pump?

A seawater pump which supply the ship fire main when the machinery space pump is not available. According to SOLAS (Chapter II-2: Construction, Part A, Reg. 4) in cargo ships of 2,000 gross tonnage and upwards, the space containing an emergency fire pump shall not be contiguous to the engine room.

Which pump is widely used in fire service?

Centrifugal pumps are most commonly used in fire protection systems, these include: horizontal split case, horizontal end suction, vertical turbine and vertical in-line. These pumps are commonly powered either by an electric motor or a diesel engine.

What are the two main categories of pumps?

Pumps are divided into 2 major categories: Dynamic and Positive Displacement (aka Displacement).

What is the best fire pump?

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 is a centrifugal fire pump?

Centrifugal pumps are the most popular fire pumps and are classified as nonpositive-displacement pumps because they do not pump a definite amount of water with each revolution. Rather, this type of pump imparts velocity to the water and converts it to pressure within the pump itself.

What is the difference between a jockey pump and a fire pump?

A jockey pump, also know as a pressure maintenance pump, maintains the pressure in the fire sprinkler system to avoid non-emergency starting of the main fire pump. … The jockey pump is designed to start before the main fire pump and return the fire protection system to its minimum static pressure.

What is the pressure of fire pump?

All new systems are required to be tested hydrostatically at a minimum pressure of either 200 psi (13.8 bar), or 50 psi (3.4 bar) above the maximum discharge pressure, whichever is greater, at the fire pump discharge flange.

What is an electric pump?

What is an Electrical pump. The electrical submersible pump is a subsurface centrifugal pump with multistage driven by an electric motor. … The electrical submersible pump is also known as “submergible” because it is mostly used in oil production to lift the oil by artificial methods.

What are the different types of fire extinguisher?

The six main fire extinguisher types are water, foam, CO2, powder, water mist and wet chemical.

Why is it called a jockey pump?

On a fire protection system requiring a fire pump, there is a small pump that maintains pressure above the pressure settings of the larger fire pump. Hence the name “jockey pump.” The purpose of a jockey pump is to maintain pressure in a fire protection piping system so the larger fire pump does not need to run.

What is a diesel fire pump?

Diesel fire pumps, also known as booster pumps, are used to boost water pressure from sources that do not provide adequate water pressure for the sprinklers to operate to a given specification. … Diesel fire pumps are often used where there is a potential reliability problem with the local electric grid.

What is the difference between booster pump and jockey pump?

A jockey pump is a small pump which maintains the pressure in a system without the aid of any other pump. It saves starting the main pump. A booster pump raises the pressure that the main pump cannot reach in order for the fluid to be able to enter the ‘high’ pressure system.

What is the use of jockey pump?

The purpose of the jockey pump is to keep the water pressure in the pipes within a specific range when there’s not a fire, so that the sprinklers won’t go off randomly. Since pipes leak, over time, the water pressure inside them automatically goes down.
