Danfoss Series 1 Fixed Piston Motors is designed to operate in mobile equipment by utilizing existing and proven technology. These motors are known for their long service life and compact size, which makes them easy to install in limited space conditions. Danfoss Series 1 fixed motors provide the required torque in high-pressure mobile applications with displacements ranging from 55 cm3 to 125 cm3 [3.3 in3 to 7.6 in3] at continuous pressures up to 420 bar [6,100 psi].
These motors come with integrated valves and improved packaging, which makes them light in weight and small in size. Due to their variable displacements and precise control management, they can be used in various applications such as agriculture, construction, lawn and turf care, wheel loaders etc. Additionally, Series 1 motors are developed with SAE mount configuration that provide compatibility, cost efficiency, ease of use, and durability.
Danfoss Power Solutions is a global leader in hydraulic and electric component manufacturing and supplying. At Rexton Hydraulic, we provide high quality services on Danfoss fixed or variable, axial piston or bent-axis. Mobile machine designers and operators worldwide have praised the Danfoss family of piston motors for their exceptional performance. Overall, Danfoss Series 1 fixed piston motors are robust, tried-and-true motors with decades of proven performance.

˜ These shaft speeds require maximum charge pressure relief: 340 psi (23 bar) pump and 280 psi (19 bar) motor.
† Maximum output torque is measured at 6000 psi (415 bar).
* Nominal Pressure: Max delta system pressure at which component fatigue does not occur (pump life estimated by bearing life).
** Peak Pressure: Max operationpressure which is permissible for a shor t duration of time (t < 1 sec).
