Haldex/Concentric Two Stage Pumps

Northern Hydraulics supplies Haldex/Concentric two stage pumps for log splitters, presses, and other high-force jobs where one cylinder needs a fast advance and a slow, high-pressure power stroke. Concentric builds these Hi/Lo gear pumps with a two-section design: both sections feed the cylinder at low pressure for rapid travel, then the high-volume section unloads as load builds so the pump can reach full system pressure. If you are matching an unmarked or discontinued unit, send the casting or part number and we will cross-reference the Haldex/Concentric equivalent.

Which Two Stage Pumps Is Right for the Job?

Choosing the right pump comes down to displacement, mounting, and whether you need the broader Concentric range or a closer match to your splitter. Start with the direct Two Stage Hydraulic Pumps listing when you know your GPM and unloading pressure and want the Hi/Lo design specifically. Step up to the full Hydraulic Pumps range if your application is single-stage or needs a fixed-displacement gear pump such as the Concentric W-series. Compare Gear Pumps when shaft, port, and rotation are the deciding factors rather than the two-stage circuit. For purpose-built replacements, the Log Splitters category groups the pumps and components most commonly fitted to splitter wedges.

Cross-Referencing Haldex/Concentric Two Stage Pumps

Concentric two stage pumps interchange across several legacy designations, and the Barnes Hi/Lo gear pumps (models 1300486, 1300487, and 1300159) are documented as drop-in equivalents to Haldex/Concentric units; the 1801521 is a confirmed Haldex Concentric match. That overlap is the value here: a faded nameplate, a long alphanumeric code like WP09A1B080R03CA102N, or a pump pulled from a 1980s splitter can usually be identified and matched to a current part. Give us the GPM rating, unloading pressure, shaft, and mount, and we will confirm the replacement or equivalent. Request a cross-reference quote.
