FLUID-SYSTEM is a leader in the design of anti-slipping system (registered patent) for hydrostatic transmissions
and will put its experience to work for you.
The flow divider is a slip preventing system for all types of hydrostatic transmissions. It provides 100%, on
demand traction for any field configuration.
FLUID-SYSTEM's flow divider is designed to suit the highest of performance and safety standards for all of our
clients.
The bidirectional flow divider controls the speed between wheels of the same axle, or between different axles
by dividing or combining the flow. It is equipped with an electric or hydraulic controlled bypass that enables a
higher operating speed on the road. It can be equally used on open or closed loop circuits.
FLUID-SYSTEM flow divider versatility allows for different installation options on many types of hydrostatic
transmissions.
→ Up to 450 bar [6527 psi]
→ Up to 200 l/min [52.8 gpm]
→ Direct in-line mounting, depending on
system configuration
→ Threaded connections :
o ISO 1179 (BSPP/Gas)
o ISO 11926 (UNF)
→ Open or closed loop circuits
→ Can work by dividing or combining the
flow

If you need to install a flushing valve in a closed loop circuit equipped with a flow divider, the flushing valve
must be installed between the pump and the flow divider.

c. TRANSFER RESTRICTOR (with orifice size)
It is located between the two outlets.
Transfer restrictor calculation:
d. CHECK VALVE ON FEEDING SYSTEM
In some applications, a receiver located in front of the flow divider can use a higher flow than the one supplied.
In this case, the oil is brought back in the line in order to protect the components from cavitation.
When a vehicle equipped with a hydrostatic transmission takes a turn, the external wheel must turn faster than
the interior one. If the divider is installed between the right and the left wheels and is activated (without the
bypass mode) while taking the turn, the check valves on the feeding system can be useful (see
“Specifications”).
Note: Trials will confirm the required sizing for the application.
