Vertical Red Single Stage Centrifugal Pump Low Noise For Fire Fighting

High Speed Red Single Stage centrifugal vertical pump Fire Fighting

Usage:

ALG vertical single stage centrifugal pumps are used to handle clean water and other liquids similar to clean water in physical and chemical properties. They are suitable for cold and hot water cyclic pressurization and equipment matching in the fields of industrial and industrial and urban water supply and discharge, pressured water supply in high-rise constructions, garden irrigation, agriculture, farm, fire control pressurization, long distance transportation, HVAC circulation, bathroom etc. Service temperature shall be lower than 80.

Introduce:

ALG series vertical single stage single suction centrifugal pumps are smartly designed on the basis  of ordinary vertical pumps jointly by our scientific and technical personnel with pump experts in China.    They use domestic advanced hydraulic model and the performance parameters of IS series centrifugal    pumps. According to the difference in service temperature, medium and conditions etc..There have    been hot water pumps, high temperature pumps, anticorrosion chemical pumps, oil pumps,        explosion-proof chemical pumps and low speed pumps derived from ALG. Featuring high efficiency, energy conservation, low noise and stable performance etc., this series of products conform to the    latest standard of JB/T53058-93 issued by Ministry of Machinery, P.R. China and are designed and manufactured to ISO2858 standard.

ALG fire fighting pumps‘ performace and technical specifications fully in compliance with the niwly enacted standard of GB6245-2006 Performance Requirements and Test Methods for Fire Pumps.

Feature:

• Vertical structure, suction and discharge given the same diameter and located on the same    centerline, to be mounted in pipeline in the way as a valve, compact and smart appearance, little  floor space required, low construction cost, and to be used outdoors if provided with a protective  cover.
•  Use of mechanical seal or mechanical seal combination for shaft seal, sealing ring made of imported titanium alloy, medium-sized high temperature resistant mechanical seal, and wear resisting seal made of hard alloy to effectively lengthen the service life of mechanical seal.
• Impeller directly mounted on the extended shaft of motor to feature short axial dimensions and compact structure. Pump and motor bearings reasonably configured to effectively balance the radial and axial load in service, thus to ensure smooth operation with little vibration and low noise.
• Easy installation and maintenance, with no need to dismantle the pipeline system. And all the rotor parts may be taken out only by taking off the nuts on pump union base.
