Abstract
The present invention relates to a method for transporting a liquid F by means of a pump P, wherein the liquid F comprises at least 10% by weight of a (meth)acrylic monomer, the pump P has a pump space (3), the pump space (3) comprises at least one transport element (4) for transporting the liquid F, the transport element (4) is connected to a drive shaft (6) in such a way that the drive shaft (6) can transmit a torque to the transport element (4), the mounting of the drive shaft is effected by means of at least two sliding bearings (5) in the pump space (3) and the sliding bearings (5) are composed of tungsten carbide.
