Is a jockey pump always required?
A jockey pump is not required on systems utilizing a fire pump, however, due to their relative simplicity, jockey pumps are the most common method used to maintain system pressure. Since jockey pumps are not required to be listed, any pump capable of producing necessary pressure is acceptable.
Is a fire pump test header required?
Where a fire pump test header is installed, NFPA 20 requires that it be installed on an exterior wall or in another location outside the pump room that allows for water discharge during testing.
What NFPA Standard contains the requirements for pump design?
NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, provides requirements for the selection and installation of fire pumps.
When should I replace my fire pump?
Horizontal split-case pumps built by most manufacturers, if installed correctly and properly maintained, should last between 25 and 40 years.
What is the difference between a jockey pump and a fire 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 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.
Do electric fire pumps require a generator?
An onsite generator must provide the secondary source of power for the fire pump. The service to the fire pump will need to meet the requirements as defined by NFPA 70: National Electrical Code (NEC) 695.3(B)(2) for service from an individual source and onsite standby generator.
How many fire pumps are required?
Fire pump pressures will be explored in further detail later. For exceptionally tall buildings, more than one fire pump may be necessary to deliver the pressure required to the higher floors. NFPA 20 permits a maximum of three pumps to operate in series (NFPA 20-2013, Section 4.19. 2.1).
How do you calculate gpm of a fire 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 the life expectancy of a fire pump?
about 20 years
Neglecting a fire pump can be expensive Failure to maintain a fire pump will minimize its useful life; the typical lifespan of the equipment is about 20 years. And replacing a fire pump costs a lot of money, as it’s the single-most expensive component of any fire protection system.
Which pipe is used for firefighting?
carbon steel pipe
Fire fighting pipe is a type of normal carbon steel pipe used to convey fire suppression agent such as water or gas. Usually it is red in color. But light-wall pipes have a galvanized exterior of a silvery appearance. Installation of red steel pipe is limited to wet pipe sprinkler systems only.
Why it is called jockey pump?
What’s new in NFPA 20 2013?
The 2013 edition of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection responds to industry developments with added coverage of water mist positive displacement pumping units. New provisions addressing diesel engine shutdowns help you avoid equipment damage during testing operations.
What is NFPA 20 for fire pumps?
Industry-trusted NFPA 20, Standard for the Installati on of Stationary Pumps for Fire Protection, offers the latest provisions to help ensure fire pump readiness and reliability. This standard offers comprehensive requirements for fire pumps, limited service controllers, and pumps in series.
What is NFPA 20 2022?
Revised to clarify an array of requirements and applications, the 2022 edition of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, further establishes best practices to help ensure state-of-the-art fire protection.
What is Chapter 5 of the NFPA 20?
The 2010 edition of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection includes an all-new Chapter 5 on high-rise buildings, with special provisions based on design practices, risk exposure, and fire fighter operations.
