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.
