NFPA-20 Centrifugal End Suction Fire Pump One Stage For Oil Terminals

For Firefighting Use Centrifugal End Suction Fire Pumps 250GPM @ 152PSI By UL / FM Listed

End Suction Centrifugal Pump Introduction:

End suction centrifugal pumps get their name from the pathway the water takes to enter the pump. Typically the water enters one side of the impeller, and on horizontal end suction pumps, this appears to enter “the end” of the pump. Unlike the HSC the suction pipe and motor or engine are all parallel, eliminating the concern about pump rotation or orientation in the mechanical room. Since water is entering one side of the impeller, you lose the ability to have bearings on both sides of the impeller. Bearing support will be either from the motor itself, or from the pump power frame. This prevents the use of this type of pump on large water flow applications.

The appeal of an end suction pump is usually its lower initial cost. If the pump can perform at a given rating and pressure, then this type of pump is adequate. If diesel-engine driven, another advantage is the ability to have an engine parallel and close to a wall (assuming proper air venting is considered). This can save space in a mechanical room piping layout.

The removal of the impeller requires pulling the impeller back out of the casing, which requires removal of the motor to provide space for this to happen. Often this is a more difficult procedure for those maintaining the pump.

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.

Performance Ranges:

Applications:

The end suction centrifugal pump is useful in various residential, industrial and commercial applications. Due to the fact that the pumps are highly common and readily available from many suppliers, their prices are usually very attractive.

Standard end suction centrifugal water pumps are normally close coupled and manufactured from standard iron or a variety of plastics. Pumps that are meant for more heavy duty commercial and industrial applications are often mounted on a bedplate with a coupling that separates the motor and the pump. These are usually available in stainless steel and more exotic alloys or plastics for corrosion resistance, while others are manufactured from hardened iron for mining, slurry and dredging applications.

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
