Not all displacements operate under the same speed limits. Model Code Serial No. Bypass valve In some applications it is desirable to bypass fluid around the variable displacement pump, for example; to allow a vehicle to move short distances at low speeds without running the prime mover. System pressure must remain at or below continuous working pressure during normal operation to achieve expected life. The power units let you put more power where More information. Retorque the sealing locknut after every adjustment to prevent an unexpected changes and to prevent external leakage. Sauer-Danfoss accepts no responsibility for possible errors in catalogs, brochures and other printed material.
The pressure compensator option features a low pressure rise short ramp to ensure optimal power utilization throughout the entire displacement range of the motor. They are NOT intended as tow valves. O ther system requirements Independet braking system, circuit overpressure protection, suitable reservoir. Reversing the angle of the swashplate reverses the flow of fluid from the pump, reversing the direction of rotation of the motor output. For definitions of the various specifications, see the related pages in this publication. Use a baffle or baffles between the reser voir inlet and outlet ports to reduce aeration and fluid surging. High pressure, which results from high load, reduces expected life.
The displacement is continuously variable by means. The recommended maximum allowable radial load is calculated as: The minimum temperature relates to the physical properties of component materials. The motor has two case danofss L1 and L2. Torque Limiter More information. Contact your Sauer-Danfoss representative for more information.
They self-regulate to give. It consists of a low-noise feed pump, a filter and a plate More information. This also applies to systems with gears or clutches using a coon reservoir.
Series 51 Series 51-1 Bent Axis Variable Displacement. Motors. Technical Information
Hydraulic pressure on the control piston must not exceed The M25, M35, and M44 pumps include a trunnion style direct displacement control. Lifetimes for speeds other than min -1 rpm can be calculated from: Two independent pumping units are operated More information. Pressures to bar psi Flows to 5. We can More information. The opposite end of the displacement control piston internally drains to the motor case.
Axial piston pumps type PVPC variable displacement, by a full line of mechanical danfoes www. X 2 is the actual distance of Fr from the mounting flange to the load for a given application. Series 20 Axial Piston Pumps. High pressure, which results from high load, reduces expected life in a manner similar to the affects of high load on other mechanical assemblies such as engines and gear boxes.
Series 40 Axial Piston Motors. Technical Information
Viscosity Maintain fluid viscosity within the continuous range for maximum efficiency and bearing life. O ther system serirs Independet braking system, circuit overpressure protection, suitable reservoir.
Other life factors include oil type and viscosity. Smooth Output Torque throughout the entire speed range of. M35, M44, and M46 variable motors have minimum displacement limiters.
The M35 and M44 MV minimum displacement limiter is located in the end cap. The M35 cove M44 variable motors feature a trunnion style swashplate and direct displacement control.
These products are manufactured in accordance with the requirements More information. The loss of hydrostatic drive line power in any mode of operation e. Minimum unit dis placement is obtained with the adjuster screw at its maximum extension from the end cap or displacement control piston cover. The M46 MV minimum displacement limiter is located in the displacement control piston cavity. The power units let you put more power where. Installations that require fluid to be removed from the low pressure side of the system circuit because of cooling requirements or contamination removal will benefit from loop flushing.
Contact your Sauer-Danfoss representative for production availability on specific frame size motors. Rated speed is the maximum recommended operating speed at full power condition.
Control N1NN necessary control pressure Control Operation N1NN 30  Servo pressure bar [psi] 20  10  minimum servo pressure under all conditions Control pressure    System pressure bar [psi]  P E min Displacement max P E Not all control options are shown in this. A loop flushing module is included on the motor. Two 2 bolt flange cartridge motor configuration. Noise Levels db a Horsepower At Pressure. Variable displacement More information. Maximum operating current is 20 ma at 5 Vdc maximum.
Reversing the angle of the swashplate reverses the flow of fluid from the pump, reversing the direction of rotation of the motor output. The controls may utilize internally supplied servo pressure.
Cold oil will not affect the durability of the motor components. Select a motor that will transmit the required torque, then select a pump that will meet the flow and pressure requirements of the motor.

Smooth Supplment Torque throughout the entire speed range of. For definitions of the various specifications, see the related pages in this publication.
SCP ISO is a series of piston pumps with a fixed displacement for mobile and stationary hydraulics. All external shaft loads have an effect on bearing life.
Introduction Dynamic Fluid Components, Inc. Definitions of these speed limits appear below. The minimum viscosity should be encountered only during brief occasions of maximum ambient temperature and severe duty cycle operation.
