Function description
KRAL screw pumps of the CLC series – high viscosity are generally suitable for transporting lubricating
liquids with high viscosity.
The design with outside bearings does not come into contact with liquid and is therefore especially suita-
ble for pumped liquids that harden when they cool down, tend to crystallize or are abrasive.
