For power plants Fluid coupling for boiler feed pump

A fluid coupling, which is installed between the driver unit (electric motor drive, etc.) and the driven unit (turbomachine, etc.), is a rotation speed control device that changes the output rotation speed while keeping the input rotation speed constant, contributing to improving operating efficiency (reduced electricity costs).

(1) Achieves operating power reduction by controlling output rotation speed according to workload
(2) Excellent shock absorption in driver unit and driven unit by using working oil for power transmission
(3) Capable of starting driven unit from close to a no-load state, so does not require a special driver design or electrical facility, even for the turbomachine with large inertia moment.
