Hydraulic Pump A2FM90

This A2FM90 is a bent-axis hydraulic pump we keep in stock for heavy mobile gear. Rated for 90 cc/rev, it’s built for pressures up to 400 bar—no frills, just solid displacement for excavators and drills.

You’ll notice the forged steel housing and tapered roller bearings. These take side loads better than standard units, so it lasts longer when your rig’s digging hard or swinging fast.

The rotating group runs on a 40° angle, which gives smooth flow from idle to full stroke. We’ve pulled worn ones apart: the cylinder bores hold up, and the valve plate wears evenly—if you keep the oil clean.

Ports are SAE split flange, two-bolt pattern. Use this pump open or closed loop; just match the charge pump if going closed. No odd adapters needed—drops into most OEM mounts with a straight splined shaft.

Before fitting, check the drain line isn’t restricted. Replace the filter and prefill with ISO VG 46. Run it low load first minute. That’s how we keep these A2FM90s running past 10,000 hours.
