Voith fluid couplings –
the solution for all start-up and clutching problems
Voith fluid couplings of the series TD, TDM-SAE and TDVFM-SAE are
start-up and damping couplings for easy installation to diesel engines.
The series TPD-SAE and TPKD-SAE additionally offers a clutching
function.
The transmission of torque in the Voith fluid
couplings occurs contact­free by the flow of the
operating fluid in the circuit – usually standard
hydraulic oil. The main components of the fluid
coupling – pump wheel (impeller) and turbine
wheel (runner) – do not touch.
Customer benefits
The connecting dimensions of the … SAE types
comply with SAE standards.
Apart from traditional diesel engines, supercharged
diesel engines and gas engines can be
started up load­free, and heavy masses can be
acceler ated without problems.
The fluid coupling in drives with diesel or gas engines provides multiple
benefits. With just one component, it always offers you a choice of the
following functions: damping – starting – overload protection – clutching.
Voith TD fluid coupling
n For damping, starting, overload
protection
n Automatic start­up of the driven
machine
n Operating errors largely absorbed
by coupling without adverse effect
n Minimum maintenance and
service requirements
n Long service life
n Easy installation
Voith TDM-SAE fluid coupling
n For damping and starting
n Automatic start­up of the driven
machine
n Operating errors largely absorbed
with out adverse effects
n Minimum maintenance and
service requirements
n Long service life
n Easy installation
Voith TPD-SAE / TPKD-SAE fluid
coupling
n For damping, starting, clutching
n Engagement possible at any
speed
n Operating errors largely absorbed
with out adverse effects
n Minimum maintenance and
service requirements
n Long service life
n Easy installation
