DP Series Precision Gear Metering Pump
Designed for medium-to-high viscosity fluid transfer. Typical applications include polyurethane, two-component adhesives, and acrylic glue. Features a multi-tooth, high-strength precision gear set with tight cavity clearance, delivering low pulsation, high linearity, and high volumetric efficiency — ensuring precise and repeatable metering per revolution.
Materials & Surface Treatment
Pump body and gears undergo high-strength heat treatment and precision grinding. DLC coating available for enhanced corrosion and wear resistance in demanding applications.
System Simplification
The unique design ensures long-term flow stability. Eliminates the need for additional valves and buffer components — lowering system cost, reducing complexity, and improving overall performance.
Typical Applications
Spraying, precision transfer, addition, dispensing, sampling, coating, and metering of medium-to-high viscosity liquids in process control systems.
