Hot Water Boiler Circulating Pump

Hot water boiler circulating pump is the core power equipment of forced circulation hot water boiler system. Its basic principle is based on centrifugal fluid mechanics and closed pipe network circulation mechanism: the motor drives the impeller to rotate at high speed to form negative pressure, sucks the system return water into the pump chamber, the medium obtains kinetic energy and pressure energy under the action of centrifugal force, completes energy conversion through the pump casing and guide vane, and pushes high-temperature hot water to form a closed cycle between the boiler body, Heat Exchanger, pipe network and end equipment with stable flow and head, continuously completing heat transmission and exchange, ensuring uniform heating, safe pressure stabilization and efficient heat supply of hot water boilers. It is an indispensable key supporting pump unit for central heating, industrial hot water, hotel bathing, park heating and other scenarios Reference: Baidu Baike · Hot Water Circulating Pump. As an original factory with more than ten years of experience in boiler supporting equipment, AIX Boiler independently researches, develops, produces and tests, focusing on creating special circulating pumps suitable for AIX full series of hot water boilers. Our products cover high temperature resistance, large flow, low noise and long service life, strictly in accordance with GB50041-2020 Code for Design of Boiler Room and CJJ/T34-2022 Code for Design of Urban Heating Pipe Network. We control the whole process from raw materials, processing, assembly to testing, providing users with cost-effective, stable and highly adaptable one-stop circulating pump solutions Reference: China Academy of Building Research · Heating Pipe Network Design Standards.

1. Structure and Core Advantages of AIX Hot Water Boiler Circulating Pump

AIX hot water boiler circulating pump adopts horizontal/vertical single-stage centrifugal pump structure, composed of pump body, impeller, shaft seal, bearing, motor, seal components, etc. The flow passage parts are made of cast iron, ductile iron or stainless steel, resistant to high temperature hot water up to 160℃, suitable for atmospheric pressure/pressure hot water boiler systems. The shaft seal adopts high temperature resistant mechanical seal, no leakage, maintenance-free and long service life; the impeller is optimized by CFD fluid design, with high hydraulic efficiency and excellent cavitation resistance, effectively avoiding cavitation damage under high temperature conditions; the rotor components are corrected by high-precision dynamic balance, with small vibration and low noise during operation, and the continuous trouble-free operation time is greatly increased. As an original factory, AIX realizes independent control of the whole process from casting processing, parts production, complete machine assembly to performance testing, refusing OEM. Each pump has passed hydraulic test, performance bench test, temperature rise test and tightness test to ensure that it meets the standard when leaving the factory. It perfectly matches the installation size, interface and control system of AIX boilers, ready for use without modification Reference: Zoomlian Pump · Boiler Circulating Pump Selection Guide.
