Fire Jockey Pump Introduction:
Any jockey pump consists of three components that include a motor, a controller and a pump. The two major types of jockey pumps are regenerative turbine pumps and centrifugal pumps. The centrifugal type is less energy efficient but requires minimal maintenance than a regenerative turbine pump. On the other hand, a regenerative turbine pump can generate high pressures with little power, but this can create excess pressure in the system. This therefore means that it requires more maintenance.
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.

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. They are inspected per NFPA 25 "Inspection and Testing of Water-Based Fire Protection Systems".
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.
