Gear Pump For Transporting Glue

Gear metering pumps used for delivering glue are specialized equipment that enhances metering accuracy and flow stability over conventional gear pumps.

They are particularly suitable for applications requiring strict control of glue delivery volume (e.g., dispensing, coating, proportioning, etc.)

Advantage of gear pump for transporting glue

1. High metering accuracy and strong flow stability
This is the core advantage of gear metering pumps, primarily due to their positive displacement operating principle:
① Flow rate is strictly linearly correlated with speed: With each gear rotation, a fixed amount of glue is delivered (determined by the volume of the gear tooth spaces). By precisely controlling the motor speed (e.g., with a servo motor or variable frequency drive system), a flow rate error of ≤±1% (some high-precision models can reach ±0.5%) can be achieved, meeting the needs of both micro-delivery of glue (e.g., dispensing glue for electronic components) and bulk, quantitative delivery (e.g., in coating production lines).

② Not affected by outlet pressure fluctuations: Even if the outlet pressure changes during glue delivery due to factors such as pipe resistance and nozzle blockage, as long as the speed is stable, the flow rate can be kept constant, avoiding problems such as uneven glue coating and dispensing amount deviation caused by pressure fluctuations.

2. Compact Structure, Easy Integration and Control
① Small Size, Flexible Installation: Gear metering pumps are typically horizontal or vertical in design, occupying a small footprint. They can be directly integrated into automated equipment such as dispensing machines and coating machines, adapting to the compact layout of production lines.
② Easy Control: The linear relationship between motor speed and flow rate allows for speed adjustment directly through control systems such as PLCs and touch screens, enabling real-time adjustments to glue delivery (e.g., quickly changing coating thickness based on product specifications). This eliminates the need for complex valve adjustments and provides fast response times (typically in milliseconds)

The core value of gear metering pumps lies in "precise metering" making them particularly suitable for applications requiring strict flow control and complex fluid characteristics during glue delivery (such as electronic dispensing, precision coating, and adhesive proportioning).

Their stability and integration make them a key device in automated glue delivery systems, effectively improving production efficiency and product quality consistency.
