Abstract: A diaphragm compressor having a compressor head with a hydraulic fluid plate having a fluid plate contact plane and a process fluid plate having a process plate contact plane, the plates forming a compression chamber when contact therebetween is established, the compression chamber being divided in an upper chamber and a lower chamber by a multi-layered diaphragm where a controller is configured for controlling an alternating movement of the multi-layered diaphragm towards the upper and the lower chambers respectively, a process fluid plate seal is positioned in a process fluid seal groove provided in the contact plane, the process fluid plate seal forms a process fluid seal between an upper side of the multi-layered diaphragm and the contact plane, and the process fluid plate includes a process fluid leak groove system fluidly connected to a process fluid plate leakage passage provided in the process fluid plate.

Abstract: A stator arrangement for an electrical motor has several windings (28) which are arranged on a winding carrier (26) of plastic. A groove (32) extends in the peripheral direction and is open to the axial end-side and in which at least one electrical conductor (30) electrically connecting two of the windings (28) is arranged. The groove (32) is formed on at least one axial end-side (20) of the winding carrier (26). An electric motor including the stator arrangement as a pump assembly with such a stator arrangement are also provided.
