2PE Series Aluminum Gear Pump, 0.50 cu in/rev, 2-Bolt SAE A Mounting Flange, 5/8 St. Keyed x 1.25, SAE A Shaft, SAE -12 Inlet, SAE -10 Outlet, CW Rotation

Normal operation should be with fluid that’s between 85 and 297 SUS. You can get away with 66 SUS, but you gotta knock the working pressure way back.

Clockwise rotation is standard out of the box. If your system runs counterclockwise, you can switch it by swapping the positions of the drive shaft and driven shaft and rotating the front flange. No special tools or parts needed for that, just a matter of reassembly before you get it mounted up.

It uses a 2-Bolt SAE A mounting flange and an SAE A shaft that is 5/8 straight keyed x 1.25, so it matches that common SAE A bolt pattern and keyed shaft style.

Clockwise is the default setup, but counter-clockwise is doable. You'd need to swap the positions of the drive shaft and driven shaft, then rotate the front flange. It's a repositioning job rather than a parts swap, so no special components required to make that change.

It uses a 2-bolt SAE A mounting flange and it comes with an SAE -12 inlet and an SAE -10 outlet, so it matches that common SAE A bolt pattern and those specific port sizes.
