Introduction
HNA10 chemical peristaltic hose pump (referred to as hose pump / peristaltic pump) is a seal-less, valve-less, strong self-priming positive displacement pump. It is specially designed for conveying chemical media that are corrosive, high-viscosity, solid particle-containing or shear-sensitive. Its core advantages include that the fluid only contacts the hose, zero leakage, and high-precision metering.
With the comprehensive strengths of seal-free design, strong self-priming capability, wide working condition adaptability and easy maintenance, it serves as an ideal choice for the conveying and metering of corrosive, high-viscosity and solid-laden media in the chemical industry. It is especially suitable for complex working conditions that traditional pumps cannot handle well.
Chemical metering peristaltic hose pump is a positive displacement volumetric pump specially designed for the chemical industry, used for high-precision conveying and metering of corrosive, high-viscosity, particle-containing or sensitive media.
The HNA10 acidic chemical peristaltic hose pump is a volumetric metering and conveying pump developed specifically for acid-base corrosive and acidic chemical media. It relies on rollers to squeeze special acid-resistant hoses to form peristaltic negative pressure, realizing self-priming, conveying and high-precision metering of media.

Advantages and Features
1. Seal-free & leak-proof Only the hose contacts the medium; no shaft seals or packing, completely avoiding chemical leakage and corrosion.
2. Excellent chemical corrosion resistance Suitable for acids, alkalis, solvents, viscous and highly corrosive chemical media.
3. Strong self-priming capability High suction lift, allows dry running without pump damage.
4. Accurate & adjustable flow Precise dosing and metering with low pulsation, ideal for chemical dosing and proportioning.
5. Simple structure & easy maintenance Only the hose is a wearing part; quick replacement and low maintenance cost.
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: Different chemicals have different corrosion effects on hoses. How to select a suitable hose?
A: Select hoses based on medium acidity, alkalinity, concentration, temperature, solvent and particle content. Natural rubber or silicone for neutral media, EPDM for weak acid and alkali, NBR for oil products, fluororubber for high-temperature organic solvents, and PTFE for strong corrosive liquids to prevent corrosion and leakage.
Q: How to inspect and repair faults of chemical peristaltic hose pump during operation?
A: Inspect in sequence of pipeline, hose, machinery and electric system. Check pipelines for air leakage, blockage and valve condition. Examine hoses and replace damaged ones properly. Verify rollers, bearings and equipment fixation. Troubleshoot electrical circuits and parameters. Conduct no-load test run, then commission with materials.
