A hot water pump is a multi-stage centrifugal pump specifically designed for conveying high-temperature hot water. Its vertical structure, multi-stage series impellers, and high-temperature resistance make it widely applicable in high-temperature hot water circulation systems. Depending on its structure, it can be categorized into vertical multi-stage hot water pumps, horizontal hot water pumps, and pipeline hot water pumps. The core features include high-temperature resistance, cavitation prevention, and energy efficiency, making it widely used in centralized heating, industrial processes, and building hot water circulation systems. It uses high-temperature mechanical seals and is equipped with a cooling flushing system, allowing it to withstand even higher water temperatures. The head range can reach from ten to several hundred meters, and the pump can be adjusted by increasing or decreasing the number of impeller stages.

The hot water pump uses high-temperature resistant materials such as cast iron and stainless steel, with graphite for sealing. It can handle hot water delivery at temperatures ranging from 80 to 200°℃. The impeller design is optimized to increase suction head, preventing the vaporization of hot water which could reduce pump efficiency or cause damage. The hot water pump is energy-efficient and uses an efficient hydraulic model to reduce energy consumption, making it suitable for long-term operation in recirculating systems. Additionally, it features reliable seals, either mechanical or packing seals, and some models come with cooling devices to prevent seal failure due to high temperatures.
Hot water pumps are commonly used in central heating systems and boiler rooms of thermal power plants. Hot water is circulated to residential areas and commercial areas to ensure stable heating for remote users, 24-hour hot water supply system, instant heating, constant temperature circulation, and energy-saving operation.
Hot water pump is the core equipment of high temperature water transportation. When selecting hot water pump, temperature, pressure, flow rate, material and sealing mode should be considered comprehensively. In centralized heating, industrial process and building hot water system, reasonable selection of hot water pump can significantly improve energy efficiency and system stability.
