How It Works
Graco Husky Series pumps operate using a simple but highly reliable air-driven system. Compressed air alternates between two chambers, flexing the diaphragms back and forth to create suction and discharge strokes. This reciprocating motion pulls fluid into one side of the pump while simultaneously pushing fluid out the other, producing a smooth, consistent flow without the need for rotating parts or mechanical seals.
Because the diaphragms, balls, and seats form the wetted path, Husky pumps can handle thick, abrasive, shear-sensitive, and even particulate-laden products with ease. Their stall-free air valve design provides efficient air consumption and prevents pump stalling, while corrosion-resistant materials ensure long service life in demanding sanitary and industrial environments.
The result is a rugged, low-maintenance pump trusted for its versatility, reliability, and ability to run dry, self-prime, and handle challenging fluids that other pump types struggle with.
