A dynamic constant fill design with dual-functionality. It integrates a driving impeller (pump) on the input shaft, a driven impeller (turbine) on the output shaft, and a sealed cover flanged to the outer impeller.
The TRANSFLUID K Series Fluid coupling functions as a hydrodynamic transmission, where impellers act as both a centrifugal pump and a hydraulic turbine. When an input drive powers the pump (like an electric motor or Diesel engine), it transfers kinetic energy to the oil within the coupling. Centrifugal force then propels the oil across the pump blades outward in the coupling.
Benefits
very smooth start-ups
protection of the motor and the driven machine from jams and overloads use
higher duration and operating convenience of the whole drive train, thanks to the protection function achieved by the fluid coupling
higher energy saving, thanks to current peak reduction
limited starting torque down to 120% in the versions with a double delayed fill chamber
same torque at input and output: the motor can supply the maximum torque even when load is jammed
torsional vibration absorption for internal combustion engines, thanks to the presence of a fluid as a power transmission element
possibility to achieve a high number of start-ups, also with an inversion of the rotation direction
load balancing in case of a double motor drive: fluid couplings automatically adjust load speed to the motors speed
high efficiency
minimum maintenance
cast iron and steel material with anticorrosion treatment
