CB Type IRG Hot water Pump

IRG 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 to transport media with a temperature not exceeding 230 ℃ and a working pressure not higher than 3 MPa.

The pump is installed horizontally, with horizontal axial suction and upward radial discharge. The pump body is a rear-opening type, and the pump body, suction and discharge pipelines can be inspected and repaired without disassembling the pump body. The shaft seal of the pump adopts mechanical seal or lead foil packing seal. The bearing is a rolling bearing and is lubricated with thin oil.EMAC will continue to update the product introduction pages of different standard versions of pumps.
