1、 Product Overview

IS type pump is a horizontal single-stage single suction clean water centrifugal pump, which is used to suction and deliver clean water and liquids with physical and chemical properties similar to water without solid particles. It is widely used in industry, agriculture, city, drainage, fire water supply, etc. The IS type pump is designed according to the performance and size specified in the international standard ISO2858, and its technical standards are close to the international standards, reaching the international advanced level. It is one of the energy-saving pump products promoted in China.

4、 Technical characteristics

1. The IS type pump is a single-stage single suction centrifugal pump, which is designed according to the international standard ISO2858. It is a new generation of the BA type pump and is suitable for industrial and urban water supply and drainage, as well as agricultural drainage and irrigation. It is used to transport clear water or other liquids with physical and chemical properties similar to clear water, and the temperature shall not exceed 80 ℃. ISR type hot water pump is a series of hot water pumps designed according to the performance and size specified in the international standard ISO2858. It is suitable for hot water boiler water supply, hot water circulation system, industrial and urban water supply, drainage and irrigation, but the temperature is not more than 150 ℃.

2. IS (R) performance range (calculated by design point):

Rotating speed: 2900r/min and 1450r/min

Inlet diameter: 50-200mm

Flow: 6.3-400mm ³/ h

Lift: 5-125m

3. Marking of pump (e.g. IS (R) 80-65-160):

　　

4. Pump selection: Users should pay attention to the following points when selecting pump specifications:

(1) The flow of the selected water pump shall be less than the normal water yield of the well or other water sources, and the dry season shall be properly considered.

(2) The lift of water pump shall be selected according to the actual demand, and the pipeline loss of water pump shall be considered.

(3) When selecting the water pump, the temperature of the liquid conveyed shall be tested and shall be less than the specified temperature value.

(4) When selecting the water pump, the installation height of the water pump shall be considered, that is, the vertical distance from the suction surface to the pump axis shall be less than the specified height of the water pump:

Estimation of pump installation height Hsz:

Hsz≤Hv-Fv- Δ Hs-[NPSH]

Hsz≤10.09- Δ Hs-[NPSH]

Where: Hv=10.33 (m) standard atmospheric pressure. (water column)

Fv=0.24 (m) Steam water pressure (water column) of clean water at normal temperature (20 ℃)

Δ Hs=suction line loss, calculated according to the actual situation.

[NPSH]=allowable NPSH.

[NPSH]=[NPSH]r+0.3(m)

[NPSH] r=required NPSH given in the performance parameter table.
