X20 Series Piston Pumps

X20 Series Open Circuit Hydraulic Piston Pump

X20 Series Open Circuit Hydraulic Piston Pump

Superior reliability and productivity in a compact package.

The Eaton X20 portfolio of open-circuit piston pumps meets the demands of mobile equipment engineers and operators looking for greater power density. The reliability and productivity of these small, lightweight pumps makes them the ideal solution for a wide range of medium-pressure mobile applications.

Common applications include sprayers, combines, harvesters, windrowers, snow removal trucks, refuse trucks, fire trucks, salt spreaders, crane/winch, telehandlers, aerial lifts, railcar movers, wheel loaders, mini excavators, backhoe loaders and crawler/dozers in the agriculture, commercial vehicle, material handling and construction segments.



Addresses these engineering challenges:


  • Need for increased pressure responsiveness that results in immediate steering response to the machine
  • Consistent flow stability throughout shifts in pressure
  • More control options (than standard gear pumps) to further drive machine efficiency
  • Need for more efficient cooling and fan drive system to help meet Tier 4 emissions standards




Product Features

  • Keep operations up and running
    • Robust, simple design with fewer parts
    • Unique control piston design that minimizes friction Long bearing life
    • Case to inlet check valve to reduce pressure spikes and protect the shaft seal
  • Maximize power for a more efficient pump
    • Low pump stand-by pressure (~150 psi) enables energy savings by reducing heat generation and wasted flow
    • Optimized valve plate design
    • Bronze shoe design that stands up against contamination
    • Compact package size to fit with Tier 4 engine requirements
  • Get the job done faster
    • Fastest response and recovery times in the market
    • High horsepower capability
  • X20 controls offering
    • Pressure Control limits outlet pressure to a set maximum
    • Load Sense limits outlet pressure to a set margin above load pressure
    • Cold Start forces pump to near-neutral when electrical current is applied
    • Torque Control limits pump torque to a set maximum
    • Remote Pressure Control limits outlet pressure proportional to signal pressure. It's ideal for applications where frequent system pressure adjustment is required due to workload requirements.
    • Fan Drive Control to Electronic Inverse Proportional Pressure Control (Fan Drive Control)
    • Electronic Proportional Pressure Control limits outlet pressure proportionally to signal current
    • Electronic Displacement Control varies the swash angle proportionally per the electrical signal current
