Abstract (en)
[origin: EP0907029A2] The pump has connection sockets with at least one formed as a connection flange (5). This has a sealing flange (8) with end-sided sealing face (11) and a surrounding one-part flange (9) for fastener elements. Sealing and fastener flanges are positively connected via a one-part holder ring (10), fitted into a circumferential groove (13) between the flanges. A suction socket and a pressure socket are located aligned on the pump housing, each with a sealing and a fastener flange.
