Introduction
The HNA90 high viscosity peristaltic hose pump is a heavy duty peristaltic pump, perfectly suited for conveying high-viscosity, particle-laden, crystallizable and slightly corrosive thick media. Adopting a seal-free and valve-free structure, this viscous fluid peristaltic hose pump features strong self-priming capacity, allows prolonged dry running, and withstands high working pressure. With its unique low-shear conveying principle, it never damages the original composition and texture of materials. Only the dedicated hose comes into contact with the medium, ensuring sanitary delivery without contamination and enabling easy cleaning and maintenance. The thick liquid transfer peristaltic hose pump supports forward and reverse operation to easily clear pipeline deposition and blockages. A wide selection of hose materials is available to adapt to different temperature and corrosive working conditions. It features a rugged structure, stable operation and low maintenance costs.
Performance Curve
Working Principle
A specially formulated rubber hose with a smooth inner wall and reliable strength is installed inside the pump body. A pair of pressure rollers rotate and squeeze along the hose. This rotational squeezing pushes the medium forward in one direction without backflow.
After conveying the medium, the hose rebounds to its original shape by its own elasticity, creating a high vacuum inside the hose to draw new medium into the lumen. The incoming medium is then discharged by the subsequent squeezing of the pressure rollers. This cycle repeats continuously, enabling constant suction and discharge of the medium.
01 The transmission device drives the rotor to rotate. Two pressure rollers mounted on the rotor and arranged at 180° to each other squeeze the hose. When the first pressure roller compresses the hose, a high vacuum is formed inside the hose, drawing the pumped medium into the hose cavity. The hose quickly returns to its original shape under its own elastic force.
02 The pumped medium has entered the hose. The second roller compresses the hose and propels the medium forward all the way to the discharge outlet.
03 At the outlet of the hose pump, one pressure roller is about to disengage from the hose, while the other roller mounted on the rotor and arranged at 180° has started squeezing the hose. This design prevents internal fluid leakage. The cycle repeats continuously, enabling uninterrupted suction and discharge of the medium.
Key Advantages
1. The HNA90 is a heavy duty peristaltic pump that can stably convey high-viscosity, particle-laden, crystallizable and slightly corrosive thick fluids.
2. Featuring a seal-free and valve-free design, it delivers excellent self-priming performance, allows prolonged dry running without damaging the pump body, boasts high pressure resistance, and offers a wide range of working condition adaptability.

FAQ
Q: The pump body and pipeline are subject to long-term erosion by a large number of ore particles in the slurry, which easily causes wear to the impeller and seals of conventional pumps, resulting in leakage, reduced flow, and frequent equipment failures.
A: The HNA90 high viscosity peristaltic hose pump only uses a dedicated hose in contact with the medium, while all other transmission components are completely isolated from the slurry, fundamentally eliminating particle erosion and wear. A high-wear-resistant hose (such as natural rubber) can be selected to withstand particle impact and long-term abrasion, significantly extending equipment service life and reducing the risk of leakage.
Q: How to troubleshoot common problems during hose pump operation?
A: Daily troubleshooting guide:
No flow output:
Check if the pipeline is blocked, or if valves are closed or clogged.
The pump hose may be ruptured, preventing liquid delivery. Replace the hose and clean the pump housing thoroughly.
Electrical failures, such as power outages, damaged circuits, motor damage, or gearbox failure.
Reduced hose pump flow:
Hose fatigue, corrosion, or abrasion.
Pump housing deformation.
Deformation of internal bearings or rollers.
Partial pipeline blockage.
