Hydraulic System Redesign Cuts Fuel Costs
The agricultural market continues to demand mobile equipment that is both more powerful and more efficient. In response to this trend, a manufacturer of sugarcane harvesters began redesigning much of their equipment. Hydraulic systems for these machines typically use gear pumps for powering hydraulic systems. Although gear pumps are low cost, compact, and reliable, they are not as efficient as other types of pumps.
This presented an opportunity to increase machine efficiency and productivity—a combination that can substantially reduce fuel consumption. The goal was at least 10% to make their product more attractive to end-users. The OEM consulted with Parker’s Global Mobile Systems (GMS) team to create a new hydraulic system that would meet its new performance goals.

Parker’s P1 series variable-displacement, axial-piston pumps for open-circuit mobile applications offer compact, quiet and efficient, performance and can deliver a continuous operating pressure to 280 bar (4,060 psi).
Redesign Reduces System Complexity
GMS completely restructured the hydraulic system by switching to a variable-displacement open-circuit solution, using P1 Series pumps with Electronic Displacement Control (EDC) and F12 Series bent-axis piston motors. Parker’s P1 variable-displacement pumps have maximum displacement of 140 cc/rev (8.5 in.3/rev) and maximum flow of 278 lpm (73 gpm) at a max speed of 2,000 rpm. Maximum operating pressure is 280 bar (4,000 psi).
