Hyvair Gear Pump 37 GPM

Hyvair’s 33 GPM gear pump (Part G33-2.3K-2BK-3) delivers reliable, high-flow performance for demanding hydraulic systems. Rated to a maximum 3000 PSI, this pump is engineered for consistent output in industrial, mobile, and heavy-duty applications where uptime and efficiency matter.

Built around a rugged 2-bolt mounting (2BK), it features a 7/8″ diameter keyed shaft with 1/4″ square key for secure power transmission and easy integration with standard drive components. This design helps minimize shaft slippage and supports smooth, efficient torque transfer under load.

To simplify plumbing and system design, the pump includes multiple female SAE ports: #20 and #24 inlets and #16 and #20 outlets. The flexible porting options make it easier to match existing hose sizes, optimize flow paths, and reduce restriction, helping maintain volumetric efficiency and reduce heat generation in the circuit.

With its compact footprint and durable construction, the Hyvair 33 GPM gear pump is an excellent choice for hydraulic power units, mobile equipment, and fixed installations that require dependable, medium-to-high flow at working pressures up to 3000 PSI. It’s designed to help keep systems running with steady performance, straightforward installation, and long service life.
