Hydraulic Gear Pumps 50 Series
SKU: 50 Series Pumps
The Cross 50 series, hydraulic gear pumps feature a gear tooth design that provides more displacement within a given package size. Available in 7 sizes, with displacements from 1.52 to 5.20 cubic inches per revolution, this compact pump can deliver up to 45 gallons per minute in a space less than 6 1/2" x 5 3/4" x 7 1/4". Gear tooth design and pressure-balanced loading plates provide high volumetric and overall efficiency while operating at a low noise level.
Pumps may be chain, belt or direct-driven by a gas engine or electric motor.
Features:
- Left, right or bi-directional rotation for pumps.
- 3000 psi (3500 psi max. shock press.)
- 3000 rpm max. continuous speed-(Limited to the maximum speed per chart below)
- 7/8 diameter shaft: 13 tooth spline or keyed
- SAE "B" 2-bolt mounting.
- SAE #16 (1") o-ring ports on bi-rotational pumps and motors.
- SAE #24 (1 1/2") or SAE #20 (1 1/4") o-ring inlet with SAE #16 (1") o-ring outlet on single rotation pumps.
