摘要

Device for removing cooling lubricant (16) from a storage reservoir (14) comprises a pump (10) and a regulating device acting on the pump and regulating the filling state of the cooling lubricant in the storage reservoir. The regulating device has a pressure sensor (24) determining the static liquid pressure in the storage reservoir and an electrical or electronic control device (28) controlling pump operation as a function of the pressure determined by the pressure sensor. Preferred Features: The control device has an adjusting button (30) for adjusting the nominal value of the filling state and a frequency converter for continuously or quasi-continuously changing the rotation of the pump.
