Mobile Hydraulic Axial Piston Pump with Volume Stop – 21 GPM (45 Degree) – 5000 PSI – 2600 RPM – 2-Bolt SAE BB, 1″ Dia. Keyed Drive Shaft – Side Porting, Inlet 1-1/2″ SAE, Outlet 1″ SAE, Case Drain #6 Female SAE – 2-Bolt SAE A, 9 Tooth Spline Through Drive – A10VSO45DFR/31R-PKC62-K01

The Hyvair A10VSO45DFR/31R-PKC62-K01 is a variable displacement axial piston pump from the A10V45 Series, fitted with a volume stop and a through drive. It is rated for 21.4 gpm, with a maximum speed of 2,600 rpm and a maximum torque of 200 Nm (1,770 in-lbs).

The pump is a swashplate design. Pistons in a rotating cylinder block stroke against an angled plate, and the plate angle sets displacement per revolution. The volume stop limits that angle so you can cap maximum flow for the circuit. The drive shaft specification lists flow adjustment.

Mounting is a 2-bolt SAE BB flange with a 1 in diameter keyed shaft, 1.375 in long, with a 1/4 in key. Ports are on the side: a 1-1/2 in SAE Code 61 flange inlet, a 1 in SAE Code 61 flange outlet and a #6 female case drain.

The rear of the pump carries a 2-bolt SAE A through drive with a 9 tooth, 16/32 DP spline. A through drive passes shaft power out the back of the pump, so a second pump with a matching SAE A mount and spline can stack directly behind it and run from the same prime mover.

Pressure rating, shaft rotation, control settings and seal material are not covered here. Confirm them against your circuit before ordering.
