Product Features

· Vertical structure ,same inlet and outlet diameters and is located on the same center line. It can be installed in

the pipeline like a valve. It has a compact and beautiful appearance, a small footprint,and a low construction investment,

such as a motor plus a protective cover. Place it for outdoor use.

· Shaft seal adopts mechanical seal. The sealing surface material: the stationary ring is a monolithic alloy or silicon

carbide, and the moving ring is graphite.with long service life 

· Easy installation and maintenance, without having to open the pipeline system, as long as the pump body

support nut can be removed to extract all the rotor components.

· According to the requirements of the use of the flow and head needs, using the pump string, parallel operation.

· The vertical or horizontal installation of the pump can be used according to the piping layout requirements.


 Product Overview

ISG series centrifugal pump is developed by our technician united with pump expert on the basis of common vertical pump,

adopting national excellent hydraulic model and performance parameter of IS centrifugal pump. 

in accordance with different working temperature and media, the hot water (IRG) pump, high temperature (GRG) pump,

corrosive chemical pump (IHG) and oil pump (YG) series products have been developed on the basis of ISG type.

This series of products has the advantages of high efficiency, low noise and good performance.


Working Conditions

· Suction pressure ≤ 1.0MPa, the maximum pump system working pressure≤ 1.6MPa, the pump hydrostatic test pressure ≤ 2.5MPa. 

· Ambient temperature < 40 degrees, relative humidity< 95%. 

· Content of solid particles in the medium per unit volume does not exceed 0.1%, particle size < 0.2mm

· Transferring medium temperature should not exceed 40 ºC. Please inform us when placing an order if the transferring medium

temperature exceeds 40 ºC. The motor power should be increased in order to adapt to the high altitude area if the altitude exceeds 1000m.

Product Application

· 1. ISG vertical pipeline centrifugal pump for conveying water or other liquids that physical and chemical properties similar to water, like industrial and urban water supply and drainage, high-rise building pressurized water, garden irrigation, fire boost, long-distance transport, HVAC refrigeration cycle, bathroom and heating equipment for pressurized water circulation, temperature < 80


· 2. IRG vertical hot water pump is used in metallurgy, chemical industry, textile, wood processing, paper and restaurants, bathrooms, hotels and other high-temperature hot water boiler loop pressurized transport and urban housing heating circulating pump, temperature below <120


· 3. GRG vertical high temperatures centrifugal pumps are widely used in Energy, metallurgy, chemicals, textiles, paper, and restaurants, bathrooms, hotels and other high-temperature hot water boiler loop pressurized transport and urban housing heating circulating pump, temperature < 240


· 4. IHG vertical pipeline chemical pumps for conveying liquids without solid particles, corrosive, viscosity similar to water, which is used in petroleum, chemical, metallurgical, power, paper, food sectors, pharmaceuticals and synthetic fibers, temperature is -20~ 120 


· 5. YG vertical pipeline pump for the transport of gasoline, kerosene, diesel and other petroleum products, medium temperature is -20 ~ + 120


· 6. ISGD Type Vertical Low-speed Piping Centrifugal Pump Mainly used for air conditioning system chilled water, cooling water circulation and end pressurization, local heating system partial or terminal pressurization cycle, as well as local constant pressure of urban building fire protection system and various air conditioning, hot water, boiler matching.
