The compact size (20% smaller than conventional gear motors), with side and rear port options, add to design flexibility for installation in tighter places. Additionally the use of high temperature seals and a dust resistant shaft seal protector improve performance and help extend operating life.
The D-motor differs slightly from the D-pumps in internal design. The D-pump uses a thicker dual pressure-balanced thrust plate design to ensure high starting torque and long life with lower viscosity oils. The design of the body allows for high axial and radial external loads without the need for an outrigger bearing assembly.
Additionally for fan drive applications, a variety of valve options are offered for great flexibility to allow for integrated reversing, proportional relief, fixed relief, and anti-cavitation valves.
