Abstract
A method stabilizes the temperature in a gear pump lubricated with material to be delivered. At least one housing part has at least two slide bearings in which shafts are mounted and are lubricated by medium to be delivered. A medium is adjusted in a temperature stabilizer to a predetermined temperature and then flows firstly through the housing part and secondly through shafts and/or slide bearings to stabilize the temperature.

Method for stabilizing a temperature in a gear pump, consisting of at least one housing part having at least two slide bearings in which shafts are mounted and lubricated by the medium being delivered, comprising:
- adjusting only a separate medium in a single temperature stabilizer to a predetermined temperature;
- and
- flowing a second medium adjusted to the predetermined temperature from the single temperature stabilizer first through the at least one housing part and second through at least one of the shafts to stabilize temperature of the material to be delivered.
Apparatus for stabilizing a temperature in a gear pump lubricated with material to be delivered by the gear pump, the gear pump comprising at least one housing part, at least two shafts, and at least two slide bearings, wherein the at least one housing part and at least one of the shafts and the slide bearings have heat exchanging line systems, and a single temperature stabilizer is operatively connectable by a supply line system with the heat exchanging line systems such that temperature of only a separate medium is adjusted to a predetermined temperature in the single temperature stabilizer before being flowed to the heat exchanging line systems.
