The Hyvair G18-2BK-3 is an external gear pump from the G Series with a rated flow of 18 gpm. It is rated for a maximum pressure of 3,770 psi. Maximum speed is listed as 3,300 to 2,000 rpm; check which limit applies at your working pressure. Inside, two meshing gears move oil around the housing, so displacement is fixed for each revolution.
Mounting is SAE B, 2 bolt, with a 7/8 in diameter keyed shaft and a 1/4 in wide square key. Confirm that your drive coupling and mounting flange match the SAE B pattern.
The pump has SAE straight thread ports. The inlet is #20 with a 1 5/8-12 thread, and the outlet is #16. Size the suction line to the full inlet so the gears stay supplied at this flow rate.
Flow follows shaft speed. Running slower reduces delivery in proportion. Keep relief valve settings at or below 3,770 psi.
The G18-2BK-3 is part of the SAE B 4 in, 16 to 41 gpm gear pump category. Compared with the 16 gpm size, it trades a small amount of pressure rating for added flow, which suits circuits that need faster cylinder or motor speeds.
