Introduction
HNA25 industrial glue transfer pumps are a type of positive displacement special pump designed specifically for conveying high-viscosity, easily curable, and shear-sensitive industrial adhesives (such as epoxy resin, silica gel, hot melt adhesive, structural adhesive, etc.). They are widely used in automatic gluing, dispensing and potting processes in industries including automotive, electronics, packaging and building materials.
Industrial adhesive hose pumps are seal-less positive displacement pumps specially designed for high-viscosity, easily curable, particle-containing or shear-sensitive adhesives. They realize material conveying mainly by squeezing special hoses, and are widely applied in dispensing, potting, coating and quantitative glue supply scenarios.
HNA25 high-viscosity glue transfer peristaltic pumps, also known as hose peristaltic pumps, are seal-less positive displacement conveying equipment professionally designed for the characteristics of various high-viscosity industrial glues. They are perfectly suitable for the conveying working conditions of high-viscosity, easily curable, solid filler-containing and shear-sensitive industrial adhesives.

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 should be done if the equipment struggles to deliver high-viscosity glue and has poor suction performance?
A: Adopt a large-volume self-priming structure with optimized and widened flow channels. It can easily adapt to high-viscosity glue, ensuring smooth suction and stable delivery.
Q: How to perform self-inspection and maintenance when the industrial glue transfer pump malfunctions?
A: For daily troubleshooting, focus on three common issues: no glue output, unstable flow rate, and abnormal noise & overheating. Check the glue liquid level, pipeline tightness, installation coaxiality and medium viscosity. Simple inspection enables quick troubleshooting of common faults of industrial glue transfer pumps.
Q: How to solve the problem of glue residue curing and frequent blockage of pumps and pipelines?
A: The pump features a smooth flow channel without dead corners to avoid glue residue retention. Its built-in anti-curing structure fundamentally prevents drying and blockage.Please feel free to contact our after-sales team if you have any problems.
