Integrated Brake Function

IBF

Danfoss has developed a system, which prevents
engine over-speeding. This feature is called
Integrated Brake Function (IBF) and is available for
series 90 pumps.

The special components are a pilot operated pressure
reducing valve and an orifice installed in the pump
end cap. They are located in the return line from the
motor and reduce the maximum pressure at the
pump while braking.

The main advantage of this function is when starting
to brake - when the pump is still at maximum angle –
the system pressure across the pump is limited to
prevent engine over-speed.

The full braking power of the engine is used in every
braking condition.

Features

•

Avoids over-speeding of the diesel
engine and other attached
components.

•

The hydrostatic braking power of the
machine is not influenced. Across the
motor, the maximum braking pressure
of 450 bar is available.

•

No change in driving comfort

•

Wear-resistant system

•

Nearly the same installation dimensions
as standard pumps

•

No electronic / sensors are necessary
