Introduction
HNA40 battery slurry hose pump, also known as peristaltic pump, is a dedicated positive displacement pump for conveying and precision metering of lithium battery anode and cathode slurry. It relies on rollers to periodically squeeze special elastic hoses to realize clean and low-shear transportation of high-viscosity, high-solid-content and highly abrasive slurry.
The lithium battery slurry conveying peristaltic hose pump is a positive displacement volumetric pump specially designed for lithium battery anode and cathode slurry featuring high viscosity, high solid content, strong corrosion resistance and pollution-free requirements. It is widely applied in electrode coating, slurry circulation and transfer processes.
The cathode slurry peristaltic hose pump is a customized conveying equipment tailored for working conditions of lithium battery cathode with high solid content, high viscosity, strong corrosion and strict prohibition of metal impurities. It is designed for batching conveying, circulating feeding and coating feeding of ternary, lithium iron phosphate and other cathode slurries. Adopting an all-hose flow structure, materials never contact metal parts, which prevents heavy metal ion contamination and ensures the cycle life and safety performance of cathode battery cells.
The HNA40 abrasive-resistant battery slurry peristaltic pump is developed specifically for lithium battery slurry containing a large number of hard powders with high abrasiveness. It is suitable for conveying anode and cathode slurry under working conditions of high solid content, high particle hardness and severe abrasion. It conveys materials through flexible hose extrusion, structurally solving industrial problems such as pump body wear, pump jamming and seal damage caused by hard powders, serving as a special volumetric conveying equipment for high-abrasion lithium battery slurry.

Advantages and Features
1. The slurry only comes into contact with the hose, with no metal ion precipitation, thus avoiding battery self-discharge and cycle life degradation.
2. It can convey slurry with 60–80% solid content and 10,000–50,000 mPa·s viscosity, without pipe clogging or sedimentation.
3. The flow rate is linearly correlated with the rotation speed, with an accuracy of ±1%, which meets the uniformity requirements of the coating and batching processes.
4. The self-priming lift can reach up to 8m, and the pump can run dry. It is immune to slurry feed interruption and air bubbles, making it suitable for closed production lines.
5. There are no sealing components, and the hose replacement takes only 5 minutes. The maintenance cost is 70% lower than that of magnetic drive pumps.
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: No obvious slurry leakage but continuous air intake and abnormal pressure and flow, what is the cause?
A: The hose has invisible tiny cracks. Air penetrates to affect conveying, and a new hose needs to be replaced.
Q: How to carry out self-inspection and maintenance for slurry hose pump faults?
A: Check pipeline unobstruction and sealing, inspect hose condition, clean filter impurities, adjust operating parameters, fasten parts, check circuit system and replace wearing parts to eliminate common operation faults.
Q: How to solve jittering operation, abnormal noise and difficult cleaning of the pump?
A: Slurry crystallization adheres inside the pump chamber. Dismantle the pump and thoroughly clean deposits.
