Paper Pulp Hose Pump

 

The HNA32 pulp hose pump, also known as peristaltic pump, is a positive displacement pump dedicated to the papermaking industry. It conveys pulp by squeezing elastic hoses with rollers, suitable for transporting high-concentration, high-viscosity pulp containing fibers and particles, as well as chemical liquids.

 

Designed for papermaking working conditions, the pump has no seals or valves. It delivers high-density fiber pulp and chemical liquids. Low shear force protects fibers and avoids foaming and pulp damage. Featuring strong self-priming capacity, anti-clogging and zero leakage, it is easy to maintain with adjustable flow, ideal for pulp feeding, sizing and chemical dosing.

 

Applicable to complex papermaking conditions, this pump transports fiber-containing pulp, liquids and wastewater. It preserves fiber integrity without foaming or pulp breakage. It boasts strong self-priming performance, anti-blocking property and leakproof operation, requiring simple maintenance with precise flow control for pulp conveying and chemical delivery procedures.

 

Tailored for papermaking scenarios, the seal-less and valve-free pump handles high-concentration pulp and liquids. Low shear performance ensures stable pulp quality without foaming. It supports dry running with powerful suction and no leakage, easy to maintain and flexible in flow regulation for pulp transfer, dosing and wastewater treatment.

 

As special conveying equipment for papermaking, the HNA32 pump adopts valveless and seal-free structure. It transports thick pulp, chemicals and sewage, protecting fibers effectively and preventing pulp deterioration. With strong suction, anti-clogging and leakproof design, it allows idle running and simple maintenance, widely used in pulp delivery, sizing, dosing and wastewater treatment.

1. Low shear protects fibers, avoiding foaming and pulp breakage to ensure pulp quality.

2. Wide applicability for high-concentration fibrous pulp, chemicals and wastewater.

3. Leak and clog resistant structure with no seals or valves, good self-priming and dry-run capability.

4. Easy maintenance, adjustable flow and accurate metering with low upkeep cost.

 

 

A special rubber hose with a smooth inner wall and reliable strength is installed inside the pump body. A pair of rollers rotate and squeeze the hose, forcing the medium to flow in one direction without backflow. After the medium is conveyed, the hose restores its original shape under its own elasticity, creating a high vacuum inside to effectively draw the medium into the lumen. The medium is then discharged from the hose under the subsequent squeezing of the rollers. This cycle repeats continuously, and the medium is constantly sucked in and discharged.
