The Hyvair G41-3K-2BK-3 is the largest external gear pump in the G Series SAE B group, rated for 41 gpm. Maximum pressure is 2,465 psi. Maximum speed is listed as 3,300 to 2,000 rpm, so check the limit for your working pressure. Two meshing gears carry oil from inlet to outlet, giving a fixed volume per revolution.
It mounts on an SAE B, 2 bolt flange, driven by a 7/8 in diameter keyed shaft with a 1/4 in wide square key. Confirm your coupling and mounting flange match.
Ports are SAE straight thread. The inlet is #24 with a 1 7/8-12 thread, and the outlet is #20 with a 1 5/8-12 thread. At 41 gpm, inlet conditions matter most; use a short, full size suction line and avoid sharp bends to keep the pump from cavitating.
Output is proportional to shaft speed, so a slower drive delivers less flow. Keep relief valve settings at or below 2,465 psi.
The G41-3K-2BK-3 tops the SAE B 4 in, 16 to 41 gpm gear pump category. Choose it when you need the most flow available from an SAE B gear pump and your circuit runs within a 2,465 psi maximum.
