Pump Curve:

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.

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.

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.
