35 jockey pump piping diagram

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. This keeps the main fire pump from short cycling, which shortens its life span. The jockey pump is designed to start before Multistage Diffuser Pumps Types TMUB, TMUAH and J Jockey Pumps Instructions • Installation • Operation • Maintenance ... that 2" or 2 ½" pipe be used for suction piping to reduce friction loss.

Jockey pump piping diagram

A jockey pump, also known as a pressure-maintenance pump, is a small apparatus that works together with a fire pump as part of a fire-protection sprinkler system. It is designed to keep the pressure in the system elevated to a specific level when the system is not in use, so that the fire pump doesn't have to run all the time and the system ... The Jockey pump is fitted with a pressure switch, which will cut in a cut off time. The jockey pump won't start unless there is a leak and the pressure in the pipe line decrease. While the pressure decreases, the cut in pressure is reached and the motor starts. When the required pressure reaches the cut off pressure, then the motor stops. facilitate isolation of the jockey pump controller (and sensing line) for maintenance without having to drain the entire system. [See Figures A-7-5.2.1 (a) and (b).] A-7.5.2.1(e) The pressure recorder should be able to record a pressure at least 150 percent of the pump discharge pressure under no-flow conditions.

Master Model JPCE, Jockey Pump Controllers, are used in installations designed to NFPA-20, Standard for the Installation of Stationary Fire Pumps for Fire Protection. They are designed to maintain the system pressure so the fire pump does not start due to small leaks in the system.

The first part is understanding that the jockey pump and the fire pump need to be located on the high-pressure side of the fire pump piping. Generally, the layout will be the pump suction or inlet, the pump discharge or outlet, and then you must pipe onto the fire pump discharge piping a ¾ "casing relief valve. A jockey pump is a small pump connected to a fire sprinkler system to maintain pressure in the sprinkler pipes. This is to ensure that if a fire-sprinkler is activated, there will be a pressure drop, which will be sensed by the fire pumps automatic controller, which will cause the fire pump to start. Jockey pumps are an optional addition. NFPA20. ULR. Fully NFPA 20 & NFPA 13R compliant. Flow rates range from 50 to 1500 GPM with pressures up to 160 PSI. System options include test headers, flow loops, city bypass loops, jockey pumps, and an array of controllers to choose from. Main fire pump and Jockey pump sensing lines totally independent of each other and connected to their respective controllers in accordance with NFPA 20 9-5.2.1. & (a), Figures A-7-5.2.1 (a) & (b). 2.

Jockey pumps mitigate false alarms by compensating for small pressure fluctuations in system piping and return the system to its normal static pressure range under non-fire conditions. As with a fire pump, the jockey pump installation will include a controller with a pressure switch. Figure A-10-5.2.1(a) Piping connection for each automatic pressure switch (for fire pump and jockey pumps). If water is clean, ground-face unions with non-corrosive diaphragms drilled for 3/32-in. orifices can be used in between the pump discharge flange and the discharge control valve, as appropriate. A.10.5.2.1 Installation of the pressure-sensing line between the discharge check valve and the control valve is necessary to facilitate isolation of the jockey pump controller (and sensing line) for maintenance without having to drain the entire system (See figure Piping 5 Setting the Pressure Switch 6 ... The controller is intended to be mounted to a wall or a welded structure that is part of the pump package. Refer to the Outline Diagram for mounting hole sizes and locations. If the controller is ...
