Product Introduction
The XR type high-temperature hot water circulation pump is designed according to AP1610 and VDMA24297 (medium light/type) specifications. It is a substitute for the original R-type hot water circulation pump, with a high degree of standardization and universality. The pump has advanced performance, operates smoothly, and is safe and reliable. A new structure was adopted in the design and production. New materials.
Scope of application
Used for conveying high-pressure hot water with a temperature less than 280C ° C and no particles in industries such as metallurgy, power plants, rubber, chemical, heating, and waste heat utilization, with a heat exchange medium not exceeding 400C ° C.
main purpose
Refineries, petrochemical industry, coal processing industry, and low-temperature engineering.
Chemical industry, papermaking, pulp industry, sugar mills, and general process industry.
Water supply plant, seawater desalination plant, metallurgy.
Heating and air conditioning systems, power plants, environmental protection engineering, ships, and seawater industry, etc.

Structural Description
The XR type hot water circulation pump is a single suction, single suction cantilever type, with horizontal axial suction and vertical upward discharge.
2. The radial part of the shell is particularly suitable for transporting high temperature, high pressure, flammable and explosive liquids, and its installation method is the horizontal center support of the pump body.
3. The suction and discharge flanges of the pump are cast on the pump body, while the shaft seal chamber and pump cover are integrated, with a water-cooled chamber jacket on the outside.
4. The bearing suspension body is cast with a large oil pool for bearing lubrication, and is equipped with a set of radial cylindrical bearings and a pair of back-to-back thrust ball bearings, which can withstand radial and axial forces.
