SYSTEMATIC CONSTRUCTION AND DEVELOPMENT OF A LOW COST SOLUTION PUMP FOR ABSORPTION HEAT PUMPS
Marketable, suitable solution pumps for absorption heat pumps are only expensive piston membrane-pumps. Marketable alternative pumps are problematical in regard to material compatibility of the well-known synthetic materials. Gear pumps are the best in output capacity. A gear pump of a hydraulic pump manufacturing company shows the best results in quiet running, volume and volumetric efficiency. In cooperating with this and another company as a specialised electromotor manufacturer this project was finished. A hermetic split internal gear pump with controllable electromotor has been realized. The result of the development is a full hermetical medium lubricated system with a 3-turned switchable electrically driven canned motor gear pump. The examinations of function and erosion which were carried out brought forth positive results and confirm a successful project finish.
