Dürr Launches EcoPump GW iD Series Gear Metering Pump

Dürr has launched its EcoPump GW iD series gear metering pump, designed for single-component (1K) and two-component (2K) industrial coating applications. The pump provides precise volumetric material delivery across flow rates from 9 to 900 ml/min to support consistent paint finishes.

Integrated Control and Protection Capabilities
The EcoPump GW iD series integrates into Dürr's ready2integrate system architecture, connecting the metering pump, control system, and application equipment into a preconfigured package.

For operational safety, the pump is optionally available with an integrated bypass valve. This valve functions as a pressure-relief mechanism that opens automatically during overpressure events to protect downstream applicators and prevent process disruptions.

Wear-Resistant Coatings and Bearing System
All models in the EcoPump GW iD line feature an Amorphous Diamond-Like Carbon (ADLC) coating applied to internal surfaces to improve wear resistance and maintain consistent dosing accuracy over extended operating cycles. Flushable variants incorporate a patented shaft bearing design engineered to extend component service life and reduce maintenance requirements.

Modular System Integration Options
The pump is designed to integrate into the Fluid Board2 dosing platform, which consolidates paint metering hardware into a compact footprint. For existing production lines, the EcoPump GW iD can be retrofitted onto previous-generation Fluid Board1 units or deployed as a standalone replacement component.

Additional Context
This section details technical specifications not included in the original news release.

Gear metering pumps operate on a positive-displacement principle, where counter-rotating precision-ground gears trap fixed volumes of fluid between the gear teeth and housing wall, transferring the medium from the inlet to the outlet port with minimal pulsation. Flow rate output is directly proportional to rotational speed, enabling precise volumetric dosing regardless of system backpressure variations.

Amorphous Diamond-Like Carbon (ADLC) coatings are thin-film vapor deposition coatings that combine high surface hardness (often exceeding 2,000 Vickers) with an extremely low coefficient of friction. This reduces abrasive wear caused by pigmented or filled paint slurries and prevents adhesive galling on internal gear faces. In multi-component (2K) coating mixing systems, precise volumetric metering prevents stoichometric imbalances between resins and hardeners, ensuring proper chemical cross-linking, curing times, and mechanical film strength.
