The GP series of paint metering and surface coating pumps

Barmag's paint metering pumps achieve flawless coating application with a high degree of reliability.

Barmag has more than 50,000 paint metering and surface coating pumps in operation throughout the world. They are used in various industrial applications, such as in automotive manufacture, in the aerospace industry and in the renewable energy sector.

The finest manufacturing tolerances and materials determine these pumps’ metering accuracy, which in turn, determines the quality of the coating on the end product.

The pumps are optimised to eliminate dead spots, to achieve short flushing times and low consumption of flushing agents, thereby maximising productivity while minimising environmental impact.

The range has been developed for use with both solvent-based and water-based paints. For metering highly abrasive paints, a DLC coating and ceramic components provides extended durability.

A flushing block provides connections for solvent feed and air pressure. Rapid colour changes are possible with this tooth flank and bearing flushing feature. These weight-optimized metering pumps are available in capacities between 1.2 cc/rev and 9 cc/rev. External dimensions are identical, meaning they are interchangeable with no changes to pipework. Special versions are produced for use with robot spraying arms.
