Product Description
[KGR High-Temperature Resistant Centrifugal Pump] Product Overview:
The KGR high‑temperature centrifugal pump has been developed by incorporating the advanced features of various leading domestic and international high‑temperature circulation pumps. It boasts a well‑designed structure, cutting‑edge technology, and high efficiency, while delivering long‑term stable operation under thermal conditions with no leakage and no need for additional cooling systems, ensuring safety and reliability. This pump is widely applicable across industries such as petroleum, lubricants, boilers, construction, road maintenance, pharmaceuticals, plastics, rubber, fiber‑containing textiles, and printing and dyeing. It is primarily used to convey weakly corrosive, ultra‑high‑temperature liquids free of solid particles, with a maximum operating temperature of ≤370°C, making it an ideal choice for high‑temperature circulation applications.
[KGR High-Temperature Resistant Centrifugal Pump] Model Designation:
[KGR High-Temperature Resistant Centrifugal Pump] Structural Features:
The KGR high‑temperature resistant centrifugal pump is a second‑generation product developed by our company through the digestion and assimilation of foreign high‑temperature circulating pumps. Its basic structural configuration is a single‑stage, single‑suction, cantilevered design with foot support; the pump inlet is axial, while the outlet is vertically upward, and both are mounted on the same base as the motor.
The KGR high‑temperature centrifugal pump employs a dual‑end ball bearing support configuration: the front end is lubricated with oil, while the rear end uses grease. A central oil‑circulation line enables continuous monitoring of the seal condition and the recovery of heat‑transfer oil. The pump features an integrated self‑heating cooling system, replacing conventional water‑cooling designs. This results in a simpler structure, reduced footprint, lower operating costs, superior performance, and reliable operation.
KGR high‑temperature‑resistant centrifugal pump: (1) It employs a combined sealing system of packing seals and mechanical seals. The packing seal uses high‑temperature‑resistant packing material with excellent thermal stability, while the mechanical seal is made of hard alloy materials that offer high mechanical strength and superior wear resistance, ensuring reliable sealing performance under elevated temperatures.
(2) The use of third-generation polytetrafluoroethylene (PTFE) as a lip seal has dramatically improved sealing performance, making it far more reliable than rubber‑based seals—its service life is 25 times longer—and it exhibits exceptionally strong corrosion resistance.
