420 Series Mobile 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. The highly efficient pump controls reduce cooling system requirements, allowing a smaller and less expensive design to be used. Or, cooling capacity can be kept the same and the flow capability of the system Increased to improve performance. 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 swashplate with steel-backed polymer bearings and a pressure lubrication passage to reduce wear and support internal loads.
