Introduction
The HNA50 alkaline chemical hose pump is an industrial-grade peristaltic pump specially designed for highly alkaline media such as sodium hydroxide, potassium hydroxide and lime milk. Fluid transfer is achieved through alternating compression of elastic hoses by rollers. It features seal-free, valve-free and zero-leakage performance, suitable for working conditions with alkaline corrosion, solid particles, high viscosity and gas-liquid mixture.
The alkaline liquid peristaltic hose pump adopts a seal-less and valve-less structure. The medium only contacts alkali-resistant hoses to prevent corrosion, leakage and crystallization jamming, applicable for conveying high-concentration alkaline liquid containing particles.
The sodium hydroxide transfer peristaltic hose pump is developed for highly alkaline media including high-concentration caustic soda and liquid alkali. With shaft-seal-free and valve-free design, the medium only touches dedicated alkali-resistant hoses, fundamentally avoiding alkali corrosion, crystallization blockage and liquid leakage.
The HNA50 chemical dedicated peristaltic hose pump is a positive displacement conveying device for harsh chemical conditions featuring strong corrosion, solid particles and high viscosity. The fully hose-based peristaltic structure without shaft seals and valves keeps the medium isolated inside dedicated hoses, effectively eliminating leakage, corrosion and blockage failures.

Advantages and Features
1. Alkali resistance and leakproof, safe and reliable Media only contacts alkali-resistant hoses without touching metal parts, effectively avoiding corrosion, crystallization jamming and leakage, suitable for highly alkaline and crystallizable media.
2. Wide working condition adaptability for complex media Capable of conveying solid-containing, high-viscosity and gas-liquid mixed fluids. It supports dry running and strong self-priming with no clogging issue.
3. Accurate metering and stable delivery Adopts positive displacement conveying principle, featuring steady flow and high precision, ideal for quantitative dosing and continuous transportation of alkaline chemicals.
4. Simple maintenance and low cost Only the hose is wearable part, easy to replace without complicated maintenance, cutting overall operation costs greatly.
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: How to deal with gradually increased metering error during operation?
A: It is mainly caused by roller wear, pipeline pressure fluctuation and medium concentration change. Replace worn parts timely, stabilize conveying conditions and calibrate flow parameters regularly.
Q: How to troubleshoot alkaline chemical hose pump faults?
A: Check hoses, rollers and blocked pipelines if flow rate is insufficient. Inspect rollers and remove medium blockage when abnormal noise and jamming occur. Replace worn hoses and fasten connectors in case of leakage. Check pipeline tightness and feeding conditions for poor self-priming performance.
