Product Description


Vickers 421AK00394C  ADU041 ADU049 ADU062 ADU080 Hydraulic Pump

420 Mobile ADU041 ADU049 ADU062 ADU080 hydraulic Eaton ADU Piston Pump 


Eaton  420 Series mobile pumps are open circuit, axial piston designs with displacements of 41cc, 49cc, 62cc, and

 80cc for operating speeds up to 2,650 rpm. They are available with a variety of control options to match their

 performance to a broad range of mobile applications. 


A strong, field-proven rotating group allows the pumps to handle pressures to 280 bar (4000 psi) continuous and 

320 bar (4600 psi) intermittent – with less maintenance cost. 420 Series pumps use a saddle type swash plate with

 steel-backed polymer bearings and a pressure lubrication passage to reduce wear and support internal loads. 

The swash plate is very stiff, which reduces deflection and allows even loading of the bearings to extend the unit’s 

service life. The combination of high load capacity bearings and a stiff drive shaft help provide a pump B10 bearing

 life of 3320 hours at rated mobile conditions, reducing operating costs and extending operating life. A single 

control piston is used to vary pump output. This design reduces the forces acting on the swash plate, resulting in 

reduced package size, which allows pump installation into tighter locations. In response to customer expectations

 and regulatory requirements, Eaton has designed the 420 Series pumps to operate at very low noise levels. 

A bimetal timing plate is used to improve pump filling characteristics which further reduces fluid-borne noise 

and extends pump life. Both SAE and ISO mounting flange configurations are available as well as SAE and ISO 

tube- and flange type ports. Side- or end-ported models are available to facilitate plumbing and help fit the pump

 to machine space needs, as are multiple drain ports to allow many mounting orientations.
