Power management company Eaton has announced that its X20 portfolio of open-circuit piston pumps now has inverse proportional pressure control and remote pressure control options for improved system efficiency in applications including construction, mining, agriculture and on-highway equipment.

The inverse proportional pressure control (IPPC) allows fan speed to be controlled independent of engine speed and load. When coupled with an X20 product, the IPPC enables accurate and efficient control of fan power, providing vehicle design engineers and system integrators another way to direct engine power. By directing power to where it is needed most during a vehicle’s operating cycle, the system saves fuel and boosts productivity. Inputs from individual temperature sensors or the vehicle’s CANbus are used to manage total vehicle cooling and enable engine aftertreatment requirements to be well-matched.

The remote pressure control is important for applications where frequent pressure adjustment is required due to varying load requirements. This control works in conjunction with a remote relief valve placed outside the system that can be manually or electronically adjusted when the system needs a change in working pressure. If dual pressure settings are required for two different work circuits, two parallel relief valves can be used in combination with a two-way valve. Applications that require this type of functionality include mobile crushers and screens, forestry or recycling chippers.  

“With these new control options, equipment manufacturers can now rely on X20 piston pumps to improve efficiency within fan drive systems and applications needing frequent pressure adjustments,” says Sonya Anderson, Mobile Open Circuit Piston Pump Product Manager, Eaton. “Working at the forefront of product innovation, the latest X20 piston pumps help meet the demands of mobile equipment engineers and operators looking for enhanced machine control.”

Additionally, all displacements offer a rear port option to meet the needs of any system configuration.

The X20 portfolio of piston pumps provides customers the flexibility of 220, 420 and 620 displacement ranges. Since the launch of the X20 series in 2005, Eaton has sold over 100,000 pumps to distributors and equipment manufacturers in construction, agriculture, commercial vehicles and material handling.

Eaton also offers an informational video outlining the new fan drive control and system.
