A hydromechanical torque control option is added to Eaton’s 420 Series product line. The 420 HM pumps are suitable for moderate-flow, high-pressure applications on compact wheel loaders, telehandlers, rough terrain forklifts, telescopic booms, sweepers, backhoe loaders, and garbage trucks. With a maximum pressure rating of 280 bar (4000 psi), the pumps offer improved power density up to 118 hp (88 kW) at 3000 rpm. Standard control options include load-sensing pressure and flow compensation. The torque control works with the compensator to replace the control piston, limiting power consumption while providing maximum flow. Pumps offer reduced noise levels and a redesigned housing with fewer parts and O-ring seals; a case to inlet check valve improves cold-weather operation.
