Aftermarket Hydraulic Gear, Piston & Vane Pumps

Provide the pump nameplate or tag together with the machine make, model and serial number. Machine badges alone may not identify the correct pump because production variants can use different components. McCann can help verify the pump manufacturer, part number, supersession information and suitable replacement route before ordering.

Yes. Weak or slow hydraulics can result from a relief valve, restricted suction line, aerated fluid, charge-pump problem, leaking cylinder or other downstream fault rather than pump wear. Pressure and flow testing under load can help isolate the cause. For hydrostatic systems, charge pressure and drive pump and motor case drain flow are important checks.

A new OEM pump is supplied through the original equipment route. An aftermarket pump or component is sourced as a compatible alternative where available. A remanufactured unit is rebuilt to OEM specification and may involve a core charge refunded when a qualifying rebuildable core is returned. Compare warranty, core terms, availability and machine requirements in writing.

System flushing is strongly indicated when a pump fails because wear debris can circulate through the reservoir, cooler, valves, cylinders and motors. Reservoir cleaning and filter replacement help protect the replacement component. Fluid cleanliness can be assessed using ISO 4406 coding, while filter efficiency is associated with ISO 16889 multi-pass testing.

Provide the machine make, model and serial number, the pump tag or nameplate information, the pump type if known, symptoms, operating conditions and any diagnostic results. Photos of the tag, ports, mounting arrangement and shaft or coupling can also help. Do not infer displacement, pressure or flow ratings from a similar pump.

McCann offers supply-and-fit service through branch shops and on-site replacement using mobile service trucks. Related work can include diagnostics, system flushing, reservoir cleaning, filter replacement and hydraulic hose support. Remanufactured installations carry parts and labour warranty according to the supplied information; confirm written warranty, core and return terms before proceeding.
