IR type hot water pump Overview: IR type hot water pump is a single stage single suction cantilever centrifugal pump, suitable for all kinds of building heating, hot water, air conditioning system and metallurgy, textile, rubber, printing and dyeing, sugar and other industrial sectors. It is used for conveying medium with temperature not exceeding 150℃ and inlet pressure not exceeding 0.8MPa. Parameters: flow Q 5.4 ~ 400 m3 / h ~ 80 m lift h 4 types: IR100-65 - J - 200 A IR - single stage single endothermic water centrifugal pump suction diameter (mm) of the 100-65 - 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. Pump body for the rear door type, can not remove the pump body, suction and discharge pipe maintenance. Pump shaft seal with packing seal or mechanical seal. The bearings are rolling bearings lubricated with thin oil. There are two kinds of pump cover: one is internal water seal hole, the other is external water seal hole, order must be clear. Direction of rotation: The pump rotates clockwise from the motor end. Main parts material: pump flow parts material, generally for gray cast iron. Range of complete sets: complete sets supply pump, motor, common base, coupling, check valve, gate valve, bottom valve, discharge taper pipe, among which the user must specify according to the pipeline device. 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.
