For manufacturers handling polyurethane, epoxy resin, hot melt glue and polymer melt, inconsistent dosing is a major production headache.
Fluctuating flow causes uneven coating, product bubbles, dimensional defects and high scrap rates. Adjusting motors or formulas often brings little improvement. The real issue is your metering pump. Common transfer pumps fail to maintain steady volumetric output under high pressure or high-viscosity conditions, wasting costly raw materials and cutting your profit.
Our square block gear metering pump is a positive displacement melt gear pump built to fix these pain points. With a rigid integrated block housing, it delivers a fixed volume per gear rotation. Its flow rate has a linear relationship with rotation speed, offering outstanding repeatability and low pulsation. Ideal for PU foaming, resin casting, slot-die coating, extrusion and fiber spinning, it stabilizes dosing and reduces reject rates.
✅ High-viscosity fluid leakage Leakage wastes expensive chemicals, contaminates equipment and increases cleaning work. Optimized sealing minimizes external leakage for high-temperature, thick media and cuts raw material loss.
✅ Frequent pump jamming & unplanned downtime Pump wear and seizure halt your whole production line. Our melt pump adopts hardened alloy gear pairs and robust block construction to withstand high pressure, extend service life and lower maintenance shutdowns.
✅ Limited space for equipment integration OEMs often struggle with compact machine cabinets. This compact square block pump uses standard flange mounting. Its integrated design simplifies installation and fits extruders, casting and coating machines. Custom displacement and port layout available.
✅ Difficult formula scaling from lab to mass production Lab-proven formulas often fail in mass production due to inaccurate dosing. Our volumetric gear pump delivers highly repeatable metering, helping you scale formulations reliably from small trials to full production.
