NFPA 20 clearly indicates that pressure maintenance (jockey) pumps do not need to be listed, but they do need to be approved. This is a big difference from the main fire pump itself which does need to be listed . This is because the function of the jockey pump is to maintain the pressure under normal conditions not to provide the fire suppression flow itself .
NFPA 20 specifies that the pressure maintenance pump be sized to refill the system pressure lost to allow leakage and normal pressure drops, with a rated capacity not less than the system normal leakage rate and discharge pressure adequate to maintain the target fire protection system pressure. In practice, this implies that jockey pump sizing is determined by the particular leakage characteristics of the system, not some generic proportion of the main pump’s capacity.
NFPA 20’s installation guidance notes that where a backflow preventer is located on the discharge side of the pump and a jockey pump is installed, the jockey pump’s discharge and sensing lines must be positioned so a cross-connection isn’t created through the jockey pump. This is a detail that’s easy to get wrong on a packaged skid layout if the jockey pump piping isn’t coordinated carefully with the backflow device location.
NFPA 20 requires a copy of the manufacturer’s certified pump test curve to be available for comparison against the results of the field acceptance test — meaning a factory-tested, pre-packaged system needs that certified curve to travel with the equipment to site, not just remain on file with the manufacturer, so the commissioning team can verify field performance against the original factory results.
NFPA 20 requires suction piping to be flushed at the rate specified in its flushing table, or the hydraulically calculated water demand rate, whichever is greater — but where the available water supply can’t provide that flow, the flushing rate must still equal or exceed 150 percent of the connected fire pump’s rated flow. This means a limited water supply doesn’t lower the flushing requirement below a defined floor, it just changes which benchmark applies.
RUHRPUMPEN designs centrifugal fire pumps and packaged fire protection systems to be compliant with the major international standards (NFPA, UL, FM, and ETL). The fire pumps and fire protection systems
RUHRPUMPEN designs centrifugal fire pumps and packaged fire protection systems to be compliant with the major international standards (NFPA, UL, FM, and ETL). The fire pumps and fire protection systems are designed to ensure reliability and compliance in high-risk environments.
The RUHRPUMPEN fire pumps are designed for long life cycles, high hydraulic efficiency, and reliable performance in emergency situations. Ronald has standalone fire pump units and complete fire protection systems in electric or diesel drives, to meet site requirements.
The design and manufacturing of these pumps (horizontal split-case) ensure that they will deliver a lot of flow when needed due to their dependability in delivering dependable flow. High-capacity fire protection systems, such as refineries, power plants, tank farms, and large industrial plants, are commonly installed in these pump’s applications.
These pumps are made to be efficient with easy access to maintenance and designed to be installed in 24/7 locations, making them an excellent choice for installations. NFPA and UL2580-512 standards govern split-case pumps. FM has approved these products for use in fire protection systems.
Typical applications include:
Benefits
These pumps are built to NFPA-20 standards and are UL-listed and FM-approved for fire protection use.
RUHRPUMPEN end suction fire pumps are an economical way to provide moderate-flow fire protection in a compact way. These single-stage centrifugal pumps are often used when there are budget and/or space constraints when considering a system layout.
RUHRPUMPEN end suction fire pumps are designed and certified according to NFPA fire pump standards and can also be configured as jockey pumps to maintain system pressure.
Typical installations include:
Benefits
RUHRPUMPEN end suction fire pumps meet NFPA-20 standards and are both UL listed and FM approved.
Vertical turbine fire pumps are designed for systems where the water supply is located below ground or where suction lift conditions exist. Common applications for vertical fire pumps are when firewater is supplied from an open body of water such as a reservoir, lake, or offshore intake structure.
RUHRPUMPEN vertical fire pumps are FM-approved and UL-listed for suction lift applications. RUHRPUMPEN vertical turbine pumps can be configured in both single stage and multi-stage arrangements to meet the delivery pressure required for the application.
Typical installations include:
Benefits
Designed to meet NFPA 20 fire protection requirements and are UL-Listed and FM Approved.
The RUHRPUMPEN In-Line Fire Pumps have been purposely designed with a reduction in footprint, as well as piping layout simplification. Their in-line design gives the opportunity for successful use directly within the piping system, leading to less structural requirements and quicker installation.
RUHRPUMPEN In-Line Fire Pumps have a compact footprint design, a top pull-out design for easy servicing, and can be used on both sprinkler and hydrant systems in high-rise buildings and industrial applications.
Typical installations include:
Benefits
The top pull-out design makes for easier maintenance access to the pump versus traditional layouts.
Jockey pumps are a crucial part of fire pump systems that are responsible for managing system pressure and preventing unnecessary activation of the main fire pump. RUHRPUMPEN jockey pumps are designed to provide consistent pressure stabilization to maintain fire protection systems in a standby condition.
Jockey pumps are normally installed next to the primary fire pumps and will help prevent minor leaks or pressure fluctuations from activating the full pump.
Typical installations include:
Benefits
Jockey pumps are essential components for maintaining fire system readiness and protecting primary pumps from wear.
