High Viscosity Pumps For Two Components A And B
This gear metering pump is specifically designed for the precise proportioning and dispensing of two-component AB adhesives (such as polyurethane, epoxy, and resin). It utilizes a precision external-meshing positive displacement gear structure with independent metering for pumps A and B. Servo-driven speed control ensures a stable output ratio of materials A and B, making it suitable for handling high-viscosity adhesives.
The pump body is constructed from stainless steel (material options available) and features precision-ground gears with controlled clearances. It offers a strictly linear relationship between flow rate and rotational speed, ensuring excellent metering repeatability and pulsation-free operation.
Ideal for potting, dispensing, casting, and continuous mixing production lines, this pump resolves issues such as inaccurate mixing ratios and significant flow fluctuations associated with high-viscosity media. It supports on-demand adjustment of the A/B ratio (customizable ratios) to meet the requirements of automated two-component adhesive injection and casting processes.
Key Features
• High metering accuracy, stable mixing ratio for 2K adhesive, reduces reject rate
• Suitable for high viscosity two-component glue (PU, epoxy resin, structural adhesive)
• Separate pump heads for A & B channel, independent servo speed adjustment, flexible ratio setting
• Multiple material options: 304,316L, Hastelloy; PTFE / PEEK sealing for chemical resistance
• Low pulsation output, smooth glue feeding for uniform mixing
• Compatible with PLC closed-loop control, easy integration into dispensing & casting automatic lines
Applications of high viscosity gear pumps
Two-component polyurethane glue, epoxy resin AB glue, potting compound, structural adhesive, resin casting material. Widely used in electronics encapsulation, composite casting, sealant production, 2K spray and continuous glue mixing production lines.

FAQ
Q: Can this pump adjust A/B mixing ratio?
A: Yes. Pump A and Pump B are driven by separate servo motors. Ratio can be adjusted freely by setting rotation speed of each pump.
Q: What glue media can it handle?
A: Suitable for polyurethane, epoxy resin and other high viscosity 2-component adhesives. For glue with solid fillers, we will check abrasion and recommend proper material.
Q: Can you supply pump head only (without motor)?
A: Yes, pump head only or complete assembly with servo motor is both available.
