Introduction
The HNA20 corrosion-resistant hose pump is a positive displacement peristaltic hose pump. It is specially designed for conveying strong acids, strong alkalis, organic solvents, particle-laden slurry and high-viscosity corrosive media in chemical, environmental protection, electroplating, water treatment and other industries.
It features leak-free operation and maintenance-free design, making it an ideal solution for conveying industrial corrosive fluids.
The industrial chemical-resistant hose pump boasts excellent tightness. Only the inner wall of the hose comes into contact with the fluid, requiring no check valves or sealing systems.

2. No mechanical friction, featuring high safety, stable operation and long service life.
3. Support forward and reverse rotation as well as dry running; the self-priming height can reach up to 9.5m.
4. Simple in structure, low in maintenance cost, easy to install and clean. It facilitates convenient maintenance and reduces downtime.
Working Principle
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.
01 The transmission device drives the rotor to rotate, and two rollers installed on the rotor and distributed at 180° squeeze the hose. When the first roller squeezes the hose, a high vacuum is created inside the hose, drawing the pumped material into the lumen. The hose then quickly returns to its original shape under its own elasticity.
02 The pumped material has now entered the hose. The second roller will squeeze the hose and push the material forward until it reaches the outlet.
03 At the hose pump outlet, one roller is about to leave the hose, while the other roller installed on the rotor (distributed at 180°) has already begun to squeeze the hose, thus preventing internal fluid leakage. This cycle repeats continuously, and the material is continuously drawn in and discharged.
Products Description
Core Component - Hose
|
NR |
NR hoses are suitable for conveying highly abrasive media, such as clay sludge, lime milk and non-organic products. Temperature range: -20°C to +80°C. |
|

Applications
● Conveyance of corrosive chemical liquids in electroplating plants
Used for circulating corrosive acid and alkaline liquids in electroplating plants. The corrosion resistant hose pump delivers excellent chemical resistance. Since the pump body does not come into contact with the medium, it enjoys a longer service life.
● Liquid transfer for pickling and passivation processes
Suitable for conveying pickling solutions in metal surface treatment. The seal-less and leak-proof design of the industrial chemical resistant hose pump eliminates potential safety hazards.
● Solvent and brine conveyance in chemical plants
Capable of long-term delivery of industrial solvents, salt water and corrosive salt slurry. The HNA20 hose pump is well suited for harsh and highly corrosive working conditions.
FAQ
