Introduction
The HNA75 mineral processing hose pump, also known as peristaltic pump or squeeze pump, is a positive displacement pump designed for highly abrasive and high-solid-content slurry. It delivers media by rotor squeezing hoses, featuring seal-free, leak-proof and dry-run capability, serving as key equipment for slurry, tailings and reagent transportation in concentrators.
Mineral slurry peristaltic pump is a positive displacement squeeze pump. It conveys materials via roller compressing elastic hoses, with only hoses contacting slurry. It suits high-solid, abrasive and particle-laden slurry, widely used in mineral processing, slag and reagent feeding.
Mineral processing hose pump is a positive displacement peristaltic conveying device. Materials are transported by roller squeezing elastic hoses. The seal-free structure ensures only hoses touch slurry, applicable to full-process slurry conveying in mineral processing.
HNA75 mining-specific peristaltic hose pump is a positive displacement conveyor. Materials are delivered through roller compression on elastic hoses. Only hoses contact slurry, adapting to harsh slurry conveying conditions in mines.
Mineral slurry peristaltic pump transports materials by squeezing hoses. It boasts abrasion resistance, zero leakage and easy maintenance, ideal for conveying various mine slurry and reagents.

Advantages and Features
1. Anti-clogging and wear-resistant: No vulnerable precise parts, suitable for high-concentration slurry with large particles and good material passing capacity.
2. Corrosion-resistant and durable: Compatible with various anti-corrosion hoses, resistant to acid and alkali erosion for long service life.
3. Precise and stable: Positive displacement delivery with constant flow and pressure, no backflow to ensure stable mineral processing.
4. Low maintenance cost: Simple structure with few wearing parts. Only hose replacement needed for easy and economical upkeep.
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.

FAQ
Q: What are the main causes of flow fluctuation during slurry conveying?
A: It is mainly caused by hose aging and deformation, pipeline air intake and offset squeezing clearance. Targeted adjustment can restore stable flow.
Q: How to conduct self-inspection and maintenance when faults occur?
A: Check pipelines, valves, hose condition and power supply, clear blockages, adjust clearance parameters and replace damaged parts.
Q: What impacts will long-term heavy-load operation bring to core components?
A: It easily causes hose fatigue and roller bearing wear, reducing conveying accuracy and service life.
