Internal‑Engaged Gear Metering Pump, 0.3% Precision Volumetric Dosing Pump for Resin Catalyst Phenolic Hot Melt Adhesive`

Our internal‑engaged gear metering pump is a heavy‑duty positive displacement volumetric dosing pump designed for stable and repeatable fluid transfer. Constructed from work tool steel with special cycloid herringbone gear structure, it achieves outstanding metering accuracy up to 0.3% and low‑pulsation output.

Well‑optimized internal clearances make this industrial gear pump compatible with high‑viscosity and shear‑sensitive media. It handles phenolic fluid, resin, catalyst, hot melt adhesive, polyurethane, glue and foaming agents reliably. Widely adopted across chemical, new material, food and pharmaceutical industries. We support full customization with complete certifications to match your production‑line dosing requirements.

0.3% High‑precision Repeatable Metering

Fixed displacement per revolution guarantees consistent output. Flow rate can be precisely controlled by adjusting rotational speed. Realize stable quantitative addition for continuous production or batch‑type filling, reduce material waste and improve product consistency.

Low‑pulsation Gentle Dosing for Sensitive Media

Unique internal gear tooth design minimizes fluid pulsation. Adjustable internal gaps protect shear‑friction‑sensitive raw materials from damage. Perfect for delicate chemical agents, resin catalyst and high‑viscosity adhesives that demand smooth transfer.

Excellent High‑viscosity Media Compatibility

Covers wide viscosity range from 100 cp to 5000000 cp. Works well with thick glue, foaming agent, phenolic resin, epoxy resin and various adhesive fluids. Adapt to complex working conditions in resin transfer and chemical dosing processes.

Robust Work Tool‑steel Construction & Wide Pressure Range

Durable work tool‑steel material delivers great wear resistance and long service life. Max working pressure reaches up to 25 MPa depending on displacement capacity. Stable performance under high‑pressure industrial dosing scenarios.

Flexible Custom‑built Solution

Custom‑bolted adapter block allows flexible inlet and outlet port layout. Displacement, mounting form, motor voltage and rotation speed can be tailored according to site conditions. Compatible with PU dispensing machines, foaming equipment, hot melt systems and filling production lines.

Working Principle

As a volumetric gear dosing pump, it relies on meshing internal gear sets to complete fluid conveyance. Driven by motor, the paired gears rotate synchronously. Under pressure difference, target medium flows into the suction chamber. The gear tooth gaps carry the medium and deliver it toward discharge side.

By adjusting motor rotational speed, operators accurately control flow volume to finish quantitative filling and continuous dosing. Optimized internal clearances ensure high volumetric efficiency for different viscosity and pressure conditions.

Wide Application Scenarios

This industrial gear metering pump serves multiple manufacturing sectors:

• Resin & phenolic industry: phenolic transfer, resin‑catalyst proportioning, epoxy resin dosing

• Adhesive & hot melt industry: hot melt adhesive system, PUR dispensing, glue metering

• Chemical & new‑material: chemical dosing, high‑viscosity agent transfer

• Foaming equipment: quantitative feeding for foaming agent, PU dispensing machine

• Food & pharmaceutical: food processing, pharmaceutical filling

• Coating industry: paint and coating quantitative metering
