General Type IR pump is the kind of single-stage single-suction overhanging centrifugal pump. It is used for heating, hot water and air-conditioner system in the various buildings and metallurgy, textile, rubber, printing and dyeing, refine sugar industry. The highest temperature of the liquid can not be over 150C. Permissible inlet pressure is not allowed more than 0. 8MPa. Performance range Capacity Q: 5. 4~ 400m3/h Head H: 4 ~ 80m The description of pump type For example IR100-65J-200A IR-Single -stage single - suction hot water pump. 100-Inlet diameter of pump ( mm ). 65-outlet diameter of pump ( mm ). J-motor rated speed is changed. 200-impeller nominal diameter ( mm ). A-A,B, C separately represents that impeller is cut the first, the second and the third time. Construction The pump is horizontally installed with horizontal axial suction and radial upward discharge. The pump is designed to back pull-out type. It is unnecessary to disturb the pump casing, the inlet piping and the outlet piping while maintenance. The shaft seal is either packing seal or mechanical seal. The pump uses rolling bearings which get lubricated with dilute oil. The cover of the pump has two types, one is with water seal hole, and the other without, please indicate it in contract. The rotation of the pump rotor The rotation of the pump rotor is clockwise looking from the motor to the pump. The material of main parts of the pump The medium-contactina parts are made of gray cast iron. Complete provision range Pump, motor, common bedplate, coupling, check valve, sluice valve, base valve and outlet cone pipe. Whether outlet cone pipe is distributed, customer must indicate it as pipeline device. Please give indication of the material of main parts of pump in contract. If you have any special requirement, please contact us without hesitation.
