The Hyvair G29-2BK-3 is a G Series external gear pump rated for 29 gpm. It has a maximum pressure of 3,190 psi. Maximum speed is listed as 3,300 to 2,000 rpm; confirm the limit that applies at your operating pressure. Two meshing gears carry oil around the housing, giving fixed displacement for each turn of the shaft.
Mounting is SAE B, 2 bolt. The pump uses a 7/8 in diameter keyed shaft with a 1/4 in wide square key. Check your coupling and mounting flange against these dimensions before ordering.
This size steps up to larger ports. The inlet is a #24 SAE straight thread port with a 1 7/8-12 thread, and the outlet is a #20 port with a 1 5/8-12 thread. Use hose and fittings sized to match so the pump is not restricted on the suction side.
Flow depends on drive speed, so a slower shaft gives proportionally less output. Set system relief pressure at or below 3,190 psi.
The G29-2BK-3 belongs to the SAE B 4 in, 16 to 41 gpm gear pump category. It suits higher flow circuits that run on an SAE B mount and stay within a 3,190 psi maximum pressure.
