Danfoss / Eaton-DUAL Servo ControlLED

Ask A Question

Description & Features

Designed for variable displacement closed circuit hydraulic systems, the Danfoss / Eaton Dual Servo Controlled pump control is built for demanding mobile equipment environments. Compatible with displacements ranging from 20cc to 49cc (1.22 to 3.00 cu in), it suits a wide range of medium-duty piston pump configurations within the 72400 Series platform.

The sealed system design supports straightforward operation and reduces maintenance complexity in field conditions. Typical applications span construction, agriculture, truck and bus, and oil and gas equipment, making it a practical choice across multiple mobile hydraulic platforms.

Flexibility across displacement ranges and application types is a key characteristic, allowing this control to be specified for varied equipment requirements without sourcing multiple part variants.

Question by: Danny S on Apr 17, 2025, 7:06 PM
Can this Eaton-Dual servo control be used on different brands of equipment, or is it specific to Danfoss systems?
Answer by: Customer Support on Apr 19, 2025, 1:01 PM
Designed for variable displacement closed circuit hydraulic systems, this servo control is compatible with displacements ranging from 20cc to 49cc (1.22 to 3.00 cu in), making it suitable for a range of medium-duty piston pump configurations within the 72400 Series platform.
Question by: Tammy P on Sep 9, 2025, 6:47 AM
got a 72400 series piston pump running on a skid steer loader and need to swap out the control, does this one cover the 35cc displacement range?
Answer by: Customer Support on Sep 11, 2025, 6:10 AM
The 72400 Series platform is exactly what this control is built around, and the supported displacement range runs from 20cc up to 49cc, so 35cc falls right in the middle of that window. As long as your pump is a variable displacement closed circuit unit within that series, this should line up with what you need.
