DECKMASTER 5.0    HYDRAULIC MOTOR TRW Ross MAF-06-0-06-A1 Displacement = 3.0 in3/ rev. Torque (theoretical) = 0.47 in-lb/psi Efficiencies: Volumetric = 0.93 Torque = 0.81 Overall = 0.75 Required Input Hydraulic Pressure (71.4)(2p) =   = 185 psi (3) (0.81) Required Input Flow (64.5)(3)  = = = 208 in3/min  =  0.90 gal/min (0.93) 6.0 HYDRAULIC PUMP Commercial Shearing P15H301GEAB5-17 Rated Pressure = 2,000 psi Flow (@ 500 psi) = 5.06 gal/min Efficiencies: Volumetric = 0.85 Overall = 0.70 Assume System Pressure Drop of 100 psi. Required Pump Output Pressure = 185 + 100 = 285 psi. Required Motor Power = (2 85)(5.06) = 1.20 HP (1714)(0.70) Note:  The above analysis has assumed three times the required levelwind traveler head speed. 2-11 *
