IRG hot water circulating pump Overview: IRG type hot water circulation pump is a single-stage single-suction cantilever centrifugal pump, suitable for hot water circulation and organic heat exchange in metallurgy, power station, chemical industry, heating waste heat utilization system or closed loop. It is used for conveying medium with temperature not exceeding 230℃ and working pressure not exceeding 3MPa. Parameters: flow Q 5.4 ~ 400 m3 / h head h 6 ~ 80 m model description: IRG100-65 - J - 200 - A which, single stage single heat water centrifugal pump suction diameter (mm) of the 100-65 - vomit outlet diameter (mm) J - said motor speed change 200 - impeller diameter (mm) A - in the name of the said impeller diameter change (B and C, respectively the second and third time cutting impeller) structure: pump is horizontal installation, horizontal axial suction, radial spit up. The pump body is in the form of rear door, without removing the pump body, suction and discharge pipelines for maintenance. Pump shaft seal with mechanical seal or packing seal. The bearings are rolling bearings lubricated with thin oil. Direction of rotation: The pump rotates clockwise from the motor end. The major parts material: material flow components of pump, I, in addition to the impeller Ⅱ class material with HT200, the rest I: QT500-7; Ⅱ ZG230-450; Ⅲ: ZG2Cr13. Complete range: complete supply pump, motor, common base, coupling, etc., while providing check valve, gate valve. When ordering, please indicate the material of main parts, if you have special requirements for pumps and motors, you can negotiate with our company about the technical requirements.
