Introduction
The HMX655 pulp and paper magnetic pump is a corrosion-resistant transfer unit tailored for pulp and paper making processes, suitable for conveying pulping chemicals, cooking liquor, bleaching liquid, wastewater and other paper-making chemical fluids. Featuring a seal-free magnetic coupling structure, chemical dosing pump for paper industry runs fully enclosed with zero leakage to stop volatilization and seepage of corrosive chemicals, fully complying with safety and explosion-proof standards for paper mills. Its wetted parts are made of premium anti-corrosion materials, standing up to strong erosion from acid, alkaline solutions and bleaching agents, and operating reliably with media containing fine fibers and pulp particles without clogging or wear.
Optimized flow channels ensure smooth operation and low pulsation, catering to continuous conveying and precise chemical dosing requirements. Compatible with major international piping standards, the corrosion resistant pump for pulp processing connects easily to existing pipelines. The compact modular design saves space and simplifies disassembly, inspection and daily maintenance. It is widely used in pulping, bleaching, chemical dosing, process waste liquid circulation and wastewater treatment, serving as an ideal pump for corrosive fluid transfer and accurate chemical feeding in the paper industry.

Key Advantages
1. Anti-clogging Flow Channel for Fiber and Pulp
Optimized with widened flow channels for media containing pulp fibers and fine particles, the HMX655 pulp and paper magnetic pump greatly reduces risks of fiber tangling and material deposition, perfectly suited for continuous feeding in pulping processes.
2. Composite Anti-corrosion System for Highly Corrosive Liquids
Fitted with custom special material combinations for bleaching liquor, acid and alkaline cooking liquor and other highly corrosive media in paper making. It withstands alternating erosion from various chemicals and features better anti-aging performance than general-purpose pumps for harsh chemical conditions.
3. Low-pulsation Structure for Precise Dosing
Optimized hydraulic design tailored for quantitative chemical feeding. This HMX655 chemical dosing pump for paper industry delivers steady flow with minimal pressure pulsation, ensuring accurate chemical proportioning and meeting high-standard dosing requirements of paper making processes.
4. Dual Sealing Protection for Wet and Dry Conditions
The reinforced integral sealing structure adapts to liquid media as well as humid and foggy workshop environments. It prevents moisture from penetrating drive components to avoid damp-related failures, ideal for high-humidity production sites in paper mills.
5. Easy Self-cleaning Structure
This paper industry chemical transfer pump features a pump chamber without complex dead corners. Residual fibers and chemicals can be quickly removed by flushing with clean water after shutdown. It simplifies maintenance, cuts manual cleaning time and reduces production downtime losses.
Typical Applications
● Pulp Slurry Conveying
As a corrosion-resistant pump for pulping processes, the HMX655 is equipped with widened anti-clogging flow channels. It smoothly delivers slurries containing fibers and fine particles, effectively preventing tangling and blockage to ensure continuous and stable feeding for pulping.
● Paper Bleaching Liquid Conveying
Made of customized composite anti-corrosion materials, the pump withstands long-term erosion from highly corrosive bleaching agents. Its low-pulsation design enables stable chemical delivery and accurate proportioning for this paper industry dosing pump.
● Chemical Circulation in Humid Workshops
The dual sealing structure blocks moisture ingress. Adapted to humid environments in paper mills, the pump rarely suffers damp-related faults and requires less maintenance.
