product description

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 replacement product of the B and BA type water pumps. It is suitable for industrial and urban water supply and drainage, and can also be used for agricultural irrigation and drainage. It is used for transporting clear water, other liquids with psical and floral properties similar to clear water, and the temperature does not exceed 80°C.

ISR type is a series of hot water pumps designed by our company according to the performance and size stipulated in the international standard ISO2858. It is suitable for water supply to hot water boilers, hot water circulation systems, and can also be used for industrial and urban water supply, drainage and irrigation, but the temperature does not exceed l50 ℃.

2. IS(R) performance range (according to design point):

Speed: 2900r/min and 1450r/min

Inlet diameter: 50-200mm

Flow:6.3-400 m³/h

IS: 80-65-160 A… J (also D)

Yang Cheng: 5-125m

4.Selection of the pump:

(1)When selecting the specifications of the water pump, the user should pay attention to the following points: (1) The flow rate of the selected water pump should be less than the normal water production of the well or other water sources;

(2)The head of the water pump should be selected according to the actual head, and the pipeline loss of the water pump should be considered.

(3)When selecting a water pump, the temperature of the conveying liquid should be considered, which should be lower than the specified temperature.

(4) When selecting a water pump, the installation height of the water pump should be considered, that is, the vertical distance from the liquid-absorbed surface to the axis of the water pump should be lower than the specified height of the water pump:

Estimation of pump installation height Hsz:

Hsz≤Hv-Fv-△Hs-[NPSH]

Hsz≤10.09-△Hs-[NPSH]

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

Fv=0.24 (m) Vaporization pressure of normal temperature water (20°C) (water column)

△Hs=Suction pipeline loss, calculated according to the actual situation.

[NPSH] = allowable NPSH.

[NPSH]=[NPSH]r+0. 3(m)

[NPSH]=Necessary NPSH given on the Performance Data Sheet
