GEARTEK 'SMD' TWO SPEED MOTOR
Geartek two-speed motors consist of two hydraulic gear motor
units with built in shift valving. Either, high speed or high torque
can be obtained, thereby improving the efficiency of winch
drives, track drives, hydrostatic transmissions
and other drive applications.
The internal valving controls input flow through both gear sets
for low speed-high torque mode, or controls the input flow
through the front section only to provide high speed-low torque
mode. Displacements of each section can be mixed relative to
one another to give ideal application speed and torques
between high and low modes.
TWO SPEED MOTOR
COMPACT SIZE
AUTOMATIC DOWNSHIFT OPTION
HYDRAULIC SHIFT ON THE GO
Advantages of these units are:
Optional automatic kick-down valve, adjustable 400-3000 psi.
Unit stays in high-speed mode until preset pressure is reached.
After shifting into low-speed mode, the unit shifts automatically
back to high-speed mode when input flow is stopped.
Optional extreme high pressure seal, which elimates required
case drain line. (Model becomes SMDH)
Compact envelope size, designed for limited space requirements.
Standard shift by remote hydraulic pilot line to tank pressure.
No external pressure required. Merely opening or closing
pilot port to tank shifts motor.

HYDRAULIC GEAR PUMPS AND MOTORS
'SLD' & 'SED'
Series
UNLOADING VALVES
The 'SLD' & 'SED' Series limits the hydraulic
horsepower which in turn limits the horsepower
required from the prime mover.
Both units can supply flow from either both sections of
the tandem pump, or from only the front section of the
unit.
With the 'SLD', when the operating pressure exceeds a
predetermined setting, an integral pilot operated relief
valve opens which moves the spool and redirects the
rear section flow from the common discharge to the
common suction.
Once the system pressure is reduced to the same
predetermined setting, the flow from the rear section
reverts back to the common discharge.
The 'SED' model allows flow through both sections
until an external 12V or 24V DC electrical signal
actuates a solenoid valve to divert flow in the rear
section similar to the 'SLD'. The pump resets to both
sections when the electrical signal is turned off.
Both models ca be manually unloaded independently
of the pilot valve or solenoid.
