summary:
The IS type pump series single-stage single suction centrifugal pump adopts the international standard ISO2858 design and is an updated product of the BA type water pump. It is suitable for industrial and urban water supply and drainage, and can also be used for agricultural irrigation and drainage. Used for conveying clean water or other liquids with physical and chemical properties similar to clean water, with a temperature not exceeding 80 ℃.
The ISR type is a series of hot water pumps designed by our company based on the performance and dimensions specified in the international standard ISO2858. It is suitable for hot water boiler feedwater, hot water circulation systems, and can also be used in industry and cities
Water supply and drainage, but the temperature should not exceed 150 ℃.
2. IS (R) performance range (based on design points):
Rotational speed: 2900r/min and 1450r/min
Imported diameter: 50-200mm
Flow rate: 6.3-400m3/h
Lift: 5-125m
3. Pump marking (e.g. IS (R) 80-6-160):
ISR (R) 80-65-160 A...... J (also known as D)
J-Deceleration Performance Pump
A - Grade of impeller cutting
160- nominal diameter of impeller (mm)
65- Discharge outlet diameter (mm)
80- Inlet diameter (mm)
IS (R) single-stage single suction clear water centrifugal pump (hot water circulation pump)
4. Pump selection: When selecting the specifications of the water pump, users 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, and appropriate consideration should be given to the dry season.
(2) The head of the water pump should be selected according to the actual required head, and the pipeline loss of the water pump should be considered.
(3) When selecting a water pump, consideration should be given to the temperature of the liquid being transported, which should be lower than the specified temperature value.
(4) When selecting a water pump, the installation height of the pump should be considered, that is, the vertical distance from the suction surface to the axis of the water pump should be less than the height specified for the water pump.
