The Hyvair G33-2.3K-2BK-3 is a G Series external gear pump with a rated flow of 37 gpm. Maximum pressure is 2,755 psi. Maximum speed is listed as 3,300 to 2,000 rpm; confirm which limit applies at your operating pressure. Meshing gears carry oil around the inside of the housing from the inlet to the outlet, so displacement is fixed.
Mounting is SAE B, 2 bolt, with a 7/8 in diameter keyed shaft and a 1/4 in wide square key. Check your motor or engine coupling and bell housing before ordering.
The ports are SAE straight thread. The inlet is a #24 port with a 1 7/8-12 thread, and the outlet is a #20 port with a 1 5/8-12 thread. At this flow rate, the suction line should be full size and as short as practical.
Flow tracks shaft speed. Running below the maximum speed reduces output in proportion. Set system relief at or below 2,755 psi to stay within the pump rating.
This pump sits in the SAE B 4 in, 16 to 41 gpm gear pump category. It delivers more flow than the 33 gpm size at a slightly lower pressure limit, which suits circuits that put cycle speed ahead of maximum force.
