VARIABLE FILL FLUID COUPLINGS

Overload Protection This is a fluid coupling advantage and a big benefit to users. Transfluid designed the KSL series variable fill fluid coupling to overcome difficulties experienced during ‘start up’ and ‘speed variation’ operation for medium or high powered machines, driven by electric motors or internal combustion engines. High Efficency The KSL is an extremely efficient device compared to the constant filled type fluid coupling, because the working circuit volume is controlled at the fullest possible level to maintain a very small slip rate. The Transfluid JET RECOVERY POWER system,...

WORKING SCHEME All parameters under control such as: speed, start up modulation, oil pressure, oil temperature, filter clogging, oil level, heat exchanger pump thermostatic control.
