Gear Pumps

The series 40 gear pumps feature a gear tooth design that provides more displacement within a given package size. Available in 6 sizes, with displacements from .50 to 1.80 cubic inch per revolution, this compact pump can deliver up to 17.5 gpm in a space less than 5” x 5 1/4”. Gear tooth design and pressure-balanced loading plates provide high volumetric and overall efficiency while operating at a low noise level.
