KPT VARIABLE FILL FLUID COUPLINGS

Product catalog summary

Description: The KPT series is a variable fill fluid coupling designed for use as a startup drive or a variable speed drive. It features an externally driven oil feeding pump and a remote electrically operated ON-OFF valve for fluid circuit control. The system ensures continuous forced bearing lubrication and allows for precise startup control and speed variation through solenoid valve modulation or oil flow control valve.

Specifications: The KPT series supports powers up to 1700 kW for startup drives and 600 kW for variable speed drives. It can be connected to electric motors or diesel engines using elastic and flexible couplings. Standard accessories include an oil motor pump, oil filter, ON-OFF electric valve, and various gauges and indicators. Optional accessories include oil flow control valves, heat exchangers, and electric control boards.

Features: The fluid coupling allows for motor startup at no load, smooth startup under nominal motor current, shock and overload protection, torsional vibration dampening, high radial load capacity, and remote control. It offers easy maintenance due to the external mounting of main accessories and has a longer lifespan due to the absence of friction linings.

Applications: The KPT series is suitable for various applications including mills, crushers, wood chippers, grinders, belt conveyors, pumps, compressors, marine propulsion, generators, centrifuges, fans, blowers, and mixers. It is also used in variable speed drives for centrifugal pumps, compressors, fans, blowers, and belt conveyors.

Working Scheme: The document includes a detailed working scheme with components such as feed pumps, flow control valves, thermostatic valves, temperature switches, coolers, and suction strainers.

Selection Tables: The document provides selection tables for fluid couplings based on maximum power and cooler models required for both variable speed and startup applications. It specifies the required water flow and cooler models for different power levels.

Dimensions: Detailed dimensions for various sizes of the KPT series are provided, including specifications for flexible and gear couplings.

Contact Information: The document lists contact details for Transfluid's global offices and distributors in China, France, the UK, the Netherlands, and the USA.

The KPT is a variable fill fluid coupling designed to be a start up drive or a variable speed drive. The KPT has an externally driven oil feeding pump and a remote electrically operated ON-OFF valve. When the valve is turned ON, the fluid coupling circuit is fed, when it is turned OFF, rapid oil drain occurs through orifices located on the periphery of the coupling. The forced bearing lubrication is continuously assured. The KPT control is achieved by on/off solenoid valve modulation or oil flow control valve (4-20mA signal) to obtain more accurate start up control and/or speed variation. The...
