2PE Series Aluminum Gear Pump, 0.68 cu in/rev, 2-Bolt SAE A Mounting Flange, 9 Tooth SAE A Splined Shaft, SAE -12 Inlet, SAE -10 Outlet, CW Rotation

3500 RPM is right at the continuous rated speed for this pump, so you're running it right at its design limit, not beyond it. It can handle intermittent bursts up to 4000 RPM if your system spikes occasionally, but for steady sustained use, staying at or just under 3500 keeps things in the safe zone. The floating bushing design helps maintain volumetric efficiency across the working pressure range, so you're not sacrificing output just because you're running it hard. As long as your fluid viscosity stays in the normal operating range of 85 to 297 SUS and your filtration meets the ISO 4406 spec, this unit should hold up fine at that duty level.
