  • Hydraulic remote control
  • Proportional solenoid control

Proven rotating group

The Series 2 pump features Eaton’s proven rotating group that’s demonstrated a strong, decades-long history of reliability.

Direct drop-in replacement

The Series 2 pump is a drop-in replacement for competitive pumps, so that you can change your pump without changing your existing machine design.

Faster pump response time

Our direct acting independent pressure override relief (IPOR) valves provide faster pump response time while allowing for different pressure settings for differing functionalities, such as forward and reverse drives.

Series 1 high-pressure variable piston pump

Reliability and durability

Known for its reliability and durability in the field, Eaton's Series 1 closed-circuit piston pump offers a price-competitive solution for your most demanding heavy-duty applications. From transit mixers to harvesters, the original Series 1 pump delivers consistent results in high-pressure applications time and time again.
