As a volumetric gear dosing pump, it relies on meshing internal gears to finish fluid transmission. Under pressure difference, medium flows into suction chamber. Rotating gears carry liquid medium and deliver it to discharge side. By adjusting motor rotation speed, users can precisely control flow volume and realize quantitative filling and continuous dosing. Adjustable internal gaps ensure high volumetric efficiency for different fluids.
This industrial gear metering pump serves multiple processing industries:
Hot melt & PUR adhesive industry: hot melt glue machine, melt‑blown equipment
Chemical & new‑material: epoxy resin, polyurethane, oleoresin, various high‑viscosity chemical dosing
Coating & paint: coating metering, paint quantitative dispensing
Food & pharmaceutical: food processing, pharmaceutical filling
Foaming equipment: foaming agent quantitative adding, PU dispensing machine
All JUSH gear metering pumps pass CE, ISO and RoHS certification. We provide 1‑year product warranty and online technical after‑sales service. Our engineering team offers custom solution consultation for special medium, pressure and flow requirements.
