Haldex/Concentric Hydraulic Pumps

Northern Hydraulics supplies and cross-references Haldex/Concentric hydraulic pumps for off-highway, industrial, and mobile equipment. Concentric (the former Haldex Hydraulic Systems Division, independent since 2011) builds the W-series gear pump families — W100, W300, W600, W900, W1200, and W1500 — spanning roughly 0.5 to 50 cc of displacement, alongside two-stage and quiet WQ/Calma designs. If you only have an old part number or a superseded Haldex/Barnes casting, send it over and we will match the cross-reference before you order.

Which Hydraulic Pumps Is Right for the Job?

The right Haldex/Concentric pump depends on flow, pressure, and how the unit mounts. Two Stage Hydraulic Pumps use a Hi/Lo design that delivers high flow at low pressure for rapid cylinder advance, then drops to low flow at high pressure for the work stroke — the standard choice for presses and splitting work. Gear Pumps are fixed-displacement single-stage units suited to steady-flow circuits, power packs, and auxiliary functions. For dedicated splitter builds, Log Splitters pair a two-stage pump with the matched components for that cycle. If you are still narrowing the family, compare the broader Two Stage Pumps group by required GPM and engine or motor input speed.

Cross-Referencing Haldex/Concentric Hydraulic Pumps

The fastest way to replace an aging unit is by cross-reference. Barnes Hi/Lo two-stage gear pumps — models 1300486, 1300487, and 1300159 — are documented as drop-in equivalents to Haldex/Concentric pumps, and the Barnes 1801521 is confirmed Haldex Concentric compatible. Haldex/Concentric pumps also carry coded designations (for example, WP09A1B080R03CA102N) that map displacement, rotation, and port configuration. Send us the casting number, the coded designation, or the failed pump's specs and we will identify the current equivalent or a compatible replacement. Request a cross-reference quote to confirm fit before ordering.

Haldex/Concentric Hydraulic Pumps — common questions

Are these genuine Haldex/Concentric products?

Yes. Every Haldex/Concentric product we list is factory-new and genuine — not aftermarket or remanufactured. Item SKUs match the manufacturer part numbers, so you can verify any model directly against Haldex/Concentric documentation.

Can you help me choose the right model?

Yes — Northern Hydraulics has supplied hydraulic equipment since 1963. Call (800) 823-4937 with your application details, or send a quote request with the model you are replacing and we will cross-reference it to the right Haldex/Concentric part.

Do you offer volume pricing on Haldex/Concentric products?

Yes. For multi-unit or recurring orders, use the Request a Quote button — volume pricing on Haldex/Concentric equipment is quoted case by case, usually within one business day.
