RH and RHX circulating hot water pumpsDetailed product description：

RH and RHX pumps are energy-saving products that have been updated and modified from R-type pumps. Its structural form and installation dimensions are exactly the same, but it has higher hydraulic efficiency and better cavitation performance.
RH and RHX hot water circulation pumps are suitable for conveying high-pressure hot water without particles below 180 ℃ or 207 ℃ in metallurgy, power plants, plastics, rubber, textile, chemical, wood and paper industries. The material of the overcurrent part of the pump is ductile iron, which is not corrosion-resistant.
Performance range of RH and RHX hot water circulation pumps (according to design points)
Flow rate: 7.2-450m3/h Head: 20-65m Inlet diameter: 40-350mm

The RH and RHX type hot water circulation pump is a single-stage single suction horizontal centrifugal pump, with the pump body as the center support, the inlet of the pump in the horizontal axis direction, and the outlet of the pump in the vertical upward direction. The impeller is fixed on the shaft with nuts, and the pump shaft is supported in the bearing bracket with a pair of single row radial thrust ball bearings and a single row radial ball bearing (or a single row radial cylindrical roller bearing). The pump body is connected to the bearing bracket with bolts, and the pump shaft is connected to the motor through an elastic pin coupling. The pump and motor are both installed on a base that matches the model.  
The sealing structure of the RH pump adopts a floating ring seal. The sealing structure of RHX pump adopts mechanical seal.
