Precision Servo-Driven Metering Pump for Two-Component Resin Injection

Precision Servo-Driven Metering Pump for Two-Component Resin Injection

We are pleased to present a tailored solution for your closed-mold resin injection process. The proposed system features

 two independently servo-controlled gear metering pumps (15 cc/rev and 12 cc/rev), enabling flexible A:B ratio adjustment

 from 100:100 down to 100:30 with exceptional accuracy.

Key Specifications per Pump:

• Effective flow range: 0.15 – 1.5 L/min (covering your 0.2–2.0 L/min target)

• Operating speed: 10 – 100 rpm

• Continuous pressure rating: 5 bar (max 10 bar safety margin)

• Fluid compatibility: Polyurethanes, isocyanates, and silicones

• Temperature: Ambient to 50°C

• Accuracy: ±0.5% volumetric repeatability

Materials & Sealing:
All wetted parts are constructed from hardened stainless steel, paired with dual-lip shaft seals designed to resist isocyanate

 crystallization and ensure leak-free operation over extended service life.

Recommended Servo Power:
400–750 W per pump, providing full torque at low speeds for consistent pressure and precise ratio control throughout the 

entire flow range.

Complete System Includes (per set):

• Gear metering pump (15 cc/rev and 12 cc/rev)

• Servo motor and drive

• Motor and encoder cables

• Flexible coupling

• Mounting bracket and hardware

This configuration delivers pulse-free flow, rapid ratio changeover, and reliable performance for both low-flow precision and 

high-throughput molding. Please contact us for pricing, lead times, or integration support.
