NFPA20 Fire Pump Set With Vertical Multistage Electric Motor Driven , Jockey Pump Set

A jockey pump is a pump connected to a fire sprinkler system and is intended to maintain pressure in a fire protection piping system to an artificially high level so that the operation of a single fire sprinkler will cause a pressure drop which will be sensed by the fire pump automatic controller, causing the fire pump to start. The jockey pump is essentially a portion of the fire pump's control system.

A jockey pump is sized for a flow less than the flow to one sprinkler in order to ensure a system pressure drop. Hence a jockey pump is an important part of the fire pumps control system. Jockey pumps are typically small multistage centrifugal pumps, and do not have to be listed or certified for fire system application. The control equipment for jockey pumps may however carry approvals.

Jockey pumps should be sized for 3% of the flow of the main fire pump and to provide 10psi more pressure than the main fire pump (As per Code IS 15105 : 2002) The application of a jockey pump in a fire protection system is provided by NFPA 20.

Fire fighting is the last protection for life and property. These include strict technical, quality and testing requirements

for fire fighting equipment that are specified in the UL/FM product standard.

Under the premise of fully learning and understanding these standards, our company has invested huge sums of money

and energy in research and development of new products. Many innovative technologies have been developed through

product R&D. The pumps and diesel engines have reached the level of first class in the world. The research and

development of these two critical products has put an end to the long history in the domestic marketplace of taking

non-certified ordinary water pumps and diesel engines and using them in life safety applications. This has also completely

changed the domestic technology level of this industry and has allowed NM FIRE to lead the market

Start by meeting the customer obvious needs, follow by continuously deepening and exploring potential customer demand,

meanwhile, plant the philosophy into our soul.
