420 Mobile Piston Pumps, Up To 38 GPM @ 1800 RPM, Up To 4060 PSI, Up To 2650 RPM

CAUTION	Highly efficient pump controls • Strong, field-proven rotating group • Saddle-type swashplate with steel-backed polymer bearings and a pressure lubrication passage to reduce wear • Stiff swashplate reduces deflection, allows for evenly loaded bearings & extends unit life • Single control piston reduces forces acting on swashplate & reduces package size • Bimetal timing plate improves pump filling characteristics which reduces fluid-borne noise and extends pump life.
Fluid Viscosity	80 to 188 SSU Recommended Operating Range, 1192 SSU Maximum Continuous, 9720 SSU Maximum at Startup.
Recommended Filtration	ISO 4406 Cleanliness Level 21/18/13 or cleaner.
