Mobile application ADU041 ADU049 ADU062 ADU080 Hydraulic Eaton ADU Piston Pump,
Eaton Vickers 421AK ADU041 Channeling pump 421AK00391A 421AK00823B ADU041R05AB10C430000002AC100CD0B Hydraulic Piston Pump,
Eaton's 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, any query, please contact us.
