Introduction
HNA50 industrial resin metering pumps are high-precision positive displacement fluid conveying equipment, designed for high-viscosity and easily-solidified media such as resins, curing agents and adhesives. They are mainly used for quantitative conveying, precise proportioning and high-pressure delivery in chemical industry, composite materials, coatings and other fields.
Resin metering peristaltic hose pumps are designed for high-viscosity and easily-solidified media including epoxy resin, unsaturated resin, curing agent and glue, which deliver materials by squeezing hoses with rollers.
Epoxy resin conveying peristaltic pumps are suitable for high-viscosity easily-solidified media like epoxy resin and curing agent. Featuring non-clogging, non-shearing and bubble-free delivery, they ensure accurate and stable metering. Only the hose contacts materials, which is corrosion-resistant, easy to clean and simple to maintain, ideal for quantitative conveying and proportioning of various resins.
The HNA50 polymer metering peristaltic hose pumps are developed for high-viscosity polymer fluids. Material is conveyed via roller hose extrusion to avoid clogging and solidification. With adjustable flow rate and accurate metering without damaging materials, the corrosion-resistant easy-to-replace hose is the only part touching media, suitable for quantitative conveying in various industries.

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 causes low flow or no discharge of industrial resin metering pumps and how to solve it?
A: It is mainly caused by clogged filters, air leakage in suction pipelines or excessive resin viscosity. Clean filter impurities, fasten pipeline joints to exhaust air, and heat properly to reduce medium viscosity for normal feeding.
Q: How to carry out self-maintenance when industrial resin metering pumps break down?
A: Daily faults can be solved by self-inspection. Clean pipeline blockages and check air leakage for abnormal flow; adjust stroke and pressure and inspect check valves for inaccurate metering; fasten fittings and match medium viscosity to eliminate abnormal noise; replace sealing parts to stop leakage; adjust pressure stabilizing components for unstable pressure; check circuits and motor conditions for abnormal operation.
Q: How to deal with inaccurate metering and uneven discharging of metering pumps?
A: It results from stuck or worn check valves and unstable back pressure. Clean and inspect check valves, adjust the set pressure of back pressure valves, and replace damaged parts to ensure accurate and stable metering.
