The Cross 40 series, 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 inches per revolution, this compact pump can deliver up to 17.7 GPM in a space less than 5" x 5 1/4" x 5 1/4". Gear tooth design and pressure-balanced loading plates provide high volume and overall efficiency while operation at a low noise level. Standard Order - Many models in stock for immediate shipment
