The single-column screen changer is integrated with an integral cylindrical screen changer and features excellent temperature and pressure resistance. Manufactured from high-temperature alloy steel, it performs outstandingly in high temperature resistance and pressure bearing. It adopts two filtration channels working alternately, enabling fast screen changing for convenient production and maintenance. Equipped with a highly wear-resistant and high-precision filter screen design, it maintains stable performance under the condition of 30-50MPa pressure and 300-400℃ temperature. The built-in material priming and exhaust structure allows continuous screen changing without material leakage or production interruption, ensuring consistent product output during the process. It supports both single-screen and double-screen filtration modes.
The single-column double-station screen changer is suitable for the production of high-pressure products, especially for almost all thermoplastics in film blowing, cast film, biaxial stretching, wire drawing, granulation and other processes.

Zhengzhou Haike is a professional enterprise engaged in the production and sales of melt pumps, high-temperature melt extrusion pumps, screen changers, high-precision filters and precision control systems (PLC). It is one of the early domestic enterprises specializing in the production of melt gear pumps and screen changers. The company independently R&D and produces a series of high-temperature melt gear pumps such as MP-S, MP-M, MP-H and MP-C, as well as a series of screen changers such as HK-ACB, HK-SSP, HK-FSP and HK-DP. At present, screen changers and melt gear pumps have been widely applied in production lines of chemical fiber, granulation, plastic film, sheet, plate, profile, pipe, wire and cable, wire drawing, composite extrusion, etc. The processable materials cover almost most polymer materials, such as PE, PC, PP, PVC, HIPS, PS, PA, TPUR, fluoropolymer, polysulfone, polyester, thermoplastic elastomer, rubber and thermal adhesive, etc.
The company integrates scientific research and production, and is committed to the development and promotion of melt gear pump and screen changer products. Drawing on the advanced technical experience of the same industry at home and abroad, we strive to build a professional melt pump manufacturing enterprise with superior products, favorable prices and perfect services.
