    The R-type hot water circulation pump is mainly composed of a pump body, impeller, shaft, cooling chamber, pump body bracket, suspension, sealing components, sealing rings, etc. The pump inlet is horizontally axial, and the outlet is vertically upward.

    The impeller undergoes static balance verification and is fixed on the shaft with impeller nuts and shaft sleeves. The pump shaft is supported on the suspension by a pair of single row radial thrust ball bearings and a single row radial ball bearing (or single row radial cylindrical roller bearing). The pump body is connected to the cooling chamber and suspension with bolts. The pump is directly driven by the motor through an elastic coupling, and from the transmission end, the pump rotates in a counterclockwise direction.

    The seal of the pump adopts a floating sealing ring seal, or high-temperature resistant packing or mechanical seal; The axial force of the pump is borne by a single row of centripetal thrust ball bearings, and some pumps use impellers with back blades to balance the axial thrust; Both the floating ring sealing component and the suspension component are equipped with cooling chambers, with an external cooling water volume of 0.3-0.6m3/h.
