Hot water network circulating pump
2025-07-03 11:44
Product Overview
Heating Network Circulation Pump It is a device used in heating systems that circulates and pressurizes hot water to facilitate its flow within the system.
The heating network circulation pump unit consists of a heating network circulation pump, a motor, and an oil-water system. The circulation pump is a horizontal axial split-casing pump with a clockwise rotation (viewed from the drive end to the free end). The pump is mounted on a rigid pump base with a suitable drainage device. A drain valve is installed on the top of the pump casing to facilitate air removal. Its horizontal centerline is split, and the inlet and outlet pipes are located in the lower half of the casing, allowing for maintenance without disassembling related pipelines. The impeller is double-suction, its structure ensures that the axial force on the impeller is basically balanced, and a bearing capable of withstanding bidirectional thrust is installed on the free end to balance the remaining axial force.
Heating network circulation pumps are generally divided into two categories: one is an electric heating network circulation pump, driven by an electric motor; the other is a steam-driven
heating network circulation pump (hereinafter referred to as steam pump), driven by an industrial steam turbine.

◆Features of Heating Network Circulation Pumps
1. Circulation: The heating network circulation pump uses its mechanism to draw hot water from the heat source or heating equipment and then transports it through pipelines to various areas requiring heating. The other end of the circulation pump also returns cold water to the heat source through pipelines for reheating, forming a circulation of hot water flow.
2. Pressure Increase: In addition to circulating hot water, the heating network circulation pump also increases system pressure. By increasing system pressure, the flow rate of hot water in the pipeline can be improved, increasing hot water transfer efficiency.
3. Control: The heating network circulation pump usually has a control system that monitors parameters such as temperature and pressure according to the actual needs of the heating system and makes corresponding adjustments. If the heating system requires more hot water, the circulation pump will automatically increase its output; conversely, if the heating system requires less hot water, the circulation pump will reduce its output appropriately to save energy.
◆Heating Network Circulation Pump Models
GS Type High-Efficiency Energy-Saving Single-Stage Double-Suction Split-Casing Pump
The GS type single-stage double-suction split-casing pump is a horizontal single-stage double-suction horizontal split-casing centrifugal pump. It is a new generation of high-efficiency energy-saving double-suction centrifugal pump products developed and innovated by Zhonglian Pump Industry, a double-suction split-casing pump manufacturer, based on the traditional S, SH, and SA double-suction split-casing pump series. It has a wide performance range, good hydraulic performance, novel structure, and versatile capabilities. The GS single-stage double-suction split-casing centrifugal pump is mainly suitable for waterworks, air conditioning circulating water, heating network systems, building water supply, irrigation, drainage pump stations, steel, power plants, industrial water supply systems, fire protection systems, shipbuilding industry, mine water supply and drainage, and other occasions for transporting liquids.

DGP Type Self-Balancing Multi-Stage Boiler Feed Pump
The DGP type self-balancing multi-stage high-pressure boiler feed pump adopts a rotor component layout with symmetrical impellers at each stage. It eliminates the balancing disk device of traditional multi-stage high-pressure boiler feed pumps. The axial forces generated during operation cancel each other out and achieve self-balancing, ensuring that the impellers and guide vanes remain balanced, improving the overall operating efficiency of the pump. It is an innovative multi-stage high-pressure boiler feed pump with a self-balancing structure and one of the models in the self-balancing multi-stage pump series. It is a substitute for multi-stage pumps with balancing disks or drums, and self-balancing technology will be a future trend in the field of multi-stage centrifugal pumps.
