X20 series 420 piston pumps
Danfoss' 420 series pumps are available with displacements of 41 cm3, 49 cm3, 62 cm3, and 80 cm3 [2.5 in3, 3 in3, 3.78 in3, and 4.88 in3] for operating speeds of 2,650 rpm. A strong, field-proven rotating group allows the pumps to handle pressures up to 280 bar [4,060 psi] continuous and 320 bar [4,600 psi] intermittent. The combination of high-load-capacity bearings and a stiff drive shaft helps provide a pump B10 bearing life of up to 10,280 hours at rated mobile conditions, reducing operating costs and extending operating life.
