NFPA20 And GB6245 Standard Multistage Booster Fire Jockey Pump With 2m³/h For Firefighting Application

Fire Jockey Pump Introduction:

The main purpose of the jockey pump is to maintain the water pressure within the pipes within a certain range when there is no fire so that the sprinklers do not randomly go off. The jockey pump also ensures that pressure in the pipes is maintained at normal pressure by refilling water into leaking pipes. In case of a fire break out and the pressure significantly drops, a jockey pump cannot keep up, and the low pressure will trigger the fire pump to start pumping water.

Additionally, the jockey pump prevents the fire sprinkler system from being damaged whenever the larger fire pump begins sending water through the system. If a fire system lacks a jockey pump to keep it pressurized, the system will develop relatively low pressure. This can lead to damage on the system as a result of the sudden change in pressure when the fire pump begins pumping water.

How To Choose:

It should be chosen so as to get into operation in a period as much as 10 minutes and bring the pressure to the desired level upon detecting a leakage that may be evident in the fire-extinguishing system.
It is selected at 1% of the nominal flow of the flow (min. 1 GPM), and at a pressure of more than 10% of the nominal pressure.

Performance Ranges:

CCCF: Q:0.25-125L/S H:0.40-2.5Mpa

NFPA20: Q: 100-1000GPM H:100-220PSI

Application:

Large hotels, hospitals , schools,office buildings,supermarkets, commercial residential buildings, metro stations, railway stations, airports, kinds of transportation tunnels, petrochemical plants, thermal power plants, terminals, oil depots, large warehouses and industrial and mining enterprises, etc.

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.

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.

Product Type:

NFPA20 Package

Advantage:

First-Class international technical standards

First-Class testing and inspection equipment.

NM Fire is the first member of NFPA from Chinese pump manufacturers .

The production of fire pump groups is strictly in accordance with NFPA20, production process and performance testing also meet the requirement of ISO9001, some kinds of products have got APSAD(France), UL , FM and CCCF certificates.

We are the only enterprise in China that obtained not only UL and FM certificates, but CCCF as well,also the first company in the world who was authorized by UL CCIC as witness testing center for both fire pumps and fire fighting engines.

UL certification represents the world's highest technical standards of fire certification,but also means that certified fire products must withstand the most extreme,harsh test process,the purpose of certification designed to verify whether the product meets the performance,safety and quality requirements,so as to achieve the purpose of property protection.

NM fire obtained fire diesel engine UL1247 and fire pump UL448 witnessed laboratory accreditation,fully proved that the company in terms of hardware and software strength,are to meet the

strict requirements of UL certification.

Service:

Wuhan Spico Machinery & Electronics Co., Ltd.（Hereinafter referred to as SPICO） is the Wuhan

office of  CNP NM Fire-fighting System Co.,Ltd (Hereinafter referred to as NM Fire). SPICO mainly resp-

onsible for product promotion，export declaration and foreign exchange collection of overseas orders.NM

Fire  is the subsidiary of Nanfang Zhongjin Environment Co.,Ltd, which islocated in Hunan Changsha

Economic and Technological Development Zone, mainly produceand sell Diesel engine &Motor fire pump

groups ,controllers and fire pumps which are in accordance with domestic & international standards and have

gotten related certifications .

With the help of multi-national engineers with more than 20 years of professional experience, the NMFIRE

technical team fully understands the technical requirements of fire fighting systems. They have overcome

difficulties, conquered technical aspects, created China's first in this industry and opened up a new market

for China's fire fighting research andtechnology.

The company’s mission is to protect the community fire safety, in line with the spirits of “integrity,

win-win”,glad to provide high cost-effective products and high-quality service for our customers.

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.
