Resin Gear Metering Pumps

Resin gear metering pumps are precision positive-displacement gear pumps designed specifically for the accurate proportioning and metered dispensing of high-viscosity reactive resins-such as epoxy, polyurethane (PU), unsaturated resins, acrylic resins, silicones, and prepolymers.

They are widely used in applications including resin dispensing, RTM (Resin Transfer Molding), vacuum casting, composite material manufacturing, coating, and the production of foamed A/B-component adhesive systems.

By independently metering the A and B components, these pumps ensure a stable mixing ratio and consistent quality in the final products.

Features of resin gear metering pumps

1. High Precision: Factory-calibrated accuracy of ±0.3% to ±0.5%. Ensures a stable mixing ratio, effectively reducing defects such as air bubbles, resin voids, incomplete curing, and uneven hardness.
2. Wide Viscosity Range: Capable of handling medium-to-high viscosity resins-ranging from several hundred to several hundred thousand cps-and supports both ambient-temperature and heated resin systems.
3. Optional Jacketed Heating/Insulation: Equipped with a thermal oil or water circulation jacket to prevent resins from cooling, thickening, crystallizing, or gelling (which could clog the pump). This is an essential feature for applications involving PU or epoxy prepolymers.
4. Simple Design: The pump chamber can be flushed with a specialized solvent during downtime, preventing resin from curing and seizing the gears.

Applications:
Epoxy resins, polyurethanes (PU) (polyols, MDI/TDI isocyanates), unsaturated polyester resins, vinyl resins, acrylic resins, silicone resins, UV-curable resins, various types of prepolymers, and resins containing low levels of fillers.

FAQ

Q1: What is the difference between a resin-metering gear pump and a standard gear pump?
A1: A standard gear pump is designed solely for fluid transfer. In contrast, a resin-metering gear pump features precision-matched gears with strictly controlled clearances, ensuring high linearity between flow rate and rotational speed, as well as excellent metering repeatability. Specifically engineered for the proportioning of A/B resin components, these pumps offer an accuracy of ±0.3% to ±0.5% and support closed-loop servo control. They are typically equipped with heating/cooling jackets, making them well-suited for high-viscosity resin systems prone to gelation.

Q2: what is the MOQ?

A1: 1 set can be delivery.
