The ELHY® devices are available in three different series, all of which exhibit the same functional principle, the same internal design and the same external shape.
The motor housing accommodates the stator of the drive motor, which is designed as a three-phase asynchronous squirrel cage motor. The motor runs in the operating fluid.
The electrical connection is established via the terminal box, which tightly seals the motor housing. The cast feet on the motor housing are used to secure the ELHY® device in place. The impeller of the pump is attached to the motor shaft.
The guide cylinder with the axially movable piston is located above the impeller. The interior of the device is filled with hydraulic fluid up to the level of the filler hole.
