T90 High Power Closed System
055/075/100 cm³
Danfoss T90 variable pump is on the base of S90 variable pump, combined with Danfoss’s the global application of experience and the latest technology to develop a new axial piston variable pump, it can cooperate T90 motor or other hydraulic products of hydraulic drive system to achieve the fluid transmission and control, mainly used in closed system.
Currently, Danfoss T90 products only for truck mixer drum drive, but also walk close system of agricultural.
For the two applications, T90 has released different configuration options for the user to select. please refer pump type code.
Series T90 variable displacement pumps are compact, high power density units. All models utilize the parallel axial piston/slipper concept in conjunction with a tiltable swashplate to vary the pump’s displacement. Reversing the angle of the swashplate re-verses the flow of oil from the pump and thus reverses the direction of rotation of the motor output.
Series T90 pumps include an integral charge pump which is manually controlled to pro-vide system replenishing and cooling oil flow, as well as control fluid flow.
Series T90 motors also use the parallel axial piston/ slipper design in conjunction with a fixed swashplate. They can intake/discharge fluid through either port; they are bidirectional. They also include an optional loop flushing feature that provides additional cooling and cleaning of fluid in the working loop.
