The Hyvair G20-2BK-3 is a G Series external gear pump rated for 20 gpm. Its maximum pressure is 3,625 psi. The maximum speed is listed as 3,300 to 2,000 rpm, so confirm the speed limit for your operating pressure. Two meshing gears carry oil from the inlet side to the outlet side, which gives the pump fixed displacement.
The pump mounts with an SAE B, 2 bolt flange. A 7/8 in diameter keyed shaft with a 1/4 in wide square key provides the drive connection. Check your coupling and adapter before installation.
Ports are SAE straight thread: a #20 inlet with a 1 5/8-12 thread and a #16 outlet. Keep the suction line short and full size to avoid starving the pump at 20 gpm.
Because flow is set by displacement and speed, a slower drive gives proportionally less flow. Set the system relief valve at or below 3,625 psi to protect the pump.
The G20-2BK-3 sits in the SAE B 4 in, 16 to 41 gpm gear pump category. It is a solid middle choice in that range for machines that need about 20 gpm from an SAE B mount and can work within a 3,625 psi limit.
