DOUBLE INTERNAL GEAR PUMP

摘要

The invention relates to a double internal gear pump (1) having two internal gear pumps (2, 2') having a common pump shaft (3). According to the invention, a partition (10) is formed between the two internal gear pumps (2, 2') having a frustoconical circumferential surface (12) which contacts an opposing surface (13) in a sealing manner in a pump housing (6). Pump inlets and pump outlets can be led through the partition (10). The frustoconical circumferential surface (12) of the partition (10) has the advantage that it makes a pressing into the pump housing (12) superfluous and canting of the partition (10) is as good as ruled out. In addition, a seal on the circumference of the partition (10) is ensured with great reliability.
