Jockey pump 50 / 60 hz Pressure Maintain Pump CDL Series Worked for Fire Fighting System

The jockey pump shall be used to maintain a constant water pressure inside the fire fighting ring main.

The jockey pump shall therefore automatically start on low pressure set point and shall stop once the

pressure has been raised to the normal operating pressure of the fire fighting system. The normal

operating pressure of the system shall be determined according to the rquirements of NFPA 20 and 24

In case where the jockey pump is not capable of maintaining the fire fighting main pressure (eg. in case

of opening of a fire hydrant during fire-fighting exercise) at the required set point, the fire fighting main

pump shall be triggered automatically to cater for the sudden drop and hence need for water. The latter

shall then be automatically switched off when the maximum operating pressure of the ring main is restored.

Specification:

CDL /CDLF Pump

CDL/CDLF is a kind of vertical non-self priming multistage contrifugal pump ,which is driven by a standard electric

motor.The motor output shaft directly connects with the pump shaft through a coupling.The pressure-resistant cylinder

and flow passage components are fixed between pump head and inlet & outlet section with stay bolts.The inlet and

outlet are located at the pump bottom at the same plane.This kind of pump can be equipped with an intelligent protector

to effectively prevent it from dry-running,out-of-phase and overload.

Operation conditions
Thin,clean,non-flammable and non-explosive liquid containing no solid granules and fibers.
Liquid temperature:

• Normal temperature type:-15℃ ~ +70℃
• Hot water type:-15℃ ~ +120℃

Ambient temperature:up to +40℃
Altitude:up to 1000m

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

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.
