KSL VARIABLE FILL FLUID COUPLINGS

Product catalog summary

Introduction
Transfluid's KSL series variable fill fluid couplings are designed to address challenges in startup and speed variation for medium to high-powered machines driven by electric motors or internal combustion engines. The couplings utilize oil as a power medium, which is pumped into a hydrodynamic circuit and drained back into a sump, allowing for controlled startup and torque management.

Working Operation
The KSL couplings operate on a variable fill principle, where oil flow is controlled via a frequency converter, altering slip characteristics for a softer startup. They offer torque limiting, disconnection capabilities, and allow for long acceleration times, sequential motor starting, and speed variation within a 5:1 range.

Characteristics
The KSL series provides a soft starter function, accurate speed variation, vibration dampening, overload protection, and high efficiency. The system includes a frequency converter electronic bypass and features such as shaft labyrinth sealing for low maintenance and easy maintenance due to its split casing design.

Applications
The KSL couplings are suitable for a variety of applications including mills, crushers, conveyors, fans, blowers, pumps, compressors, centrifuges, mixers, generators, and marine propulsion drives.

Selection Criteria
To select the appropriate KSL coupling, Transfluid requires information on motor/engine type, power, speed, driven machinery type, environmental conditions, and other technical specifications.

Performance
The document provides performance data, indicating that standard squirrel cage motors should not be derated and that the efficiency of electric motors is unaffected by KSL applications. Slip can vary by ±10% based on machine characteristics.

Dimensions and Weight
Dimensions and weights for various KSL models are provided, with a note that dimensions are subject to change without notice.

Application Examples
Examples include installations in ceramic mills and fan drives, with specific power and speed configurations.

Additional Information
Details on optional features, such as auxiliary lubrication units and ATEX certification, are available upon request. The document also includes contact information for Transfluid's global offices.

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, provides...
