How it Works
The end suction centrifugal pump normally contains a single impeller and a spiral like casing. The fluid that is being pumped moves along the impeller’s vanes, which increases the fluid’s velocity. From there the fluid is moved into the spiral like casing, where the high velocity is transformed into high pressure by a diffusion process.

These types of pumps are usually powered by an A.C. electric motor, although some are D.C. motor driven, as well as air driven motors, hydraulic motors, gasoline and diesel engine driven and steam turbine driven. These pumps may be close-coupled, with the impeller directly attached to the driver shaft without a separate coupling between them.

Alternatively, they may be mounted on a frame, where the pump has its own bearings and a coupling that separates the motor and the pump.

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.
