Abstract: A vacuum pump (10) includes a pump unit (14) and an operating unit (12) arranged spaced from the pump unit (14). The operating unit (12) is connected with the pump unit (14) for controlling it. The pump unit (14) and the operating unit (12) respectively comprise a transceiver module (20,22) for transmitting and receiving control and operational data bidirectionally in a wireless manner. The pump unit (14) and the operating unit (12) are exclusively connected with each other in a wireless manner. By the omission of electrical lines, the induction of interfering signals is excluded. Wall perforations for lead-through of electrical lines are omitted.

Abstract: A test-gas leak detector (1) includes a connection (27) for a device under test, a sniffer, or a leak detector chamber, a high-vacuum pump (2), a test-gas detector (5) that is connected on the intake side of said pumps, and a test-gas conduit (28) leading from the connection of the leak detector (27). The conduit is connected to at least one intermediate stage of the high-vacuum pump (2) in addition to the pre-vacuum zone of the high-vacuum pump (2) via conduit sections (31, 32, 35) and valves (33, 34, 36). A housing (9), in which at least some of the conduits and valves and the high-vacuum pump (2) are integrated, forms part of the leak detector (1) and a detachable slide-in module (51) forms part of the high-vacuum pump. The slide-in module has an external jacket construction (53) comprising passages (58, 61) and when the leak detector (1) is operational, is situated in a receiving opening (52) that is provided in the housing (9).

Abstract: A vacuum pump (10) includes a control device (20) for processing operational data and operational instructions. Further, the vacuum pump (10) includes a touch screen (40) serving as display for displaying the operational data callable from the control device (20) and as input for inputting operational instructions into the control device (20). The touch screen (40) includes a display panel (42) and a key panel (44) as display and the input, respectively, and is connected with the control device (20) via a data line (36). By combining the display and the input in a single device, namely the touch screen, the trouble for display and data input is reduced.

Abstract: A vacuum pump (1, 30) has an inlet (5) and an outlet (6). Plug-in screw fittings (9) are connected with the inlet and the outlet. The plug-in screw fittings include a bore with an internal bevel (22) that receives a flexible connecting line (23), a chuck collet (19), and an O-ring (21) frictionally in a vacuum-tight relationship. In this manner, a more simple and versatile connection is provided between the vacuum pump and the connecting lines.

Abstract: The invention relates to an oscillating piston pump (1), in particular to an oscillating piston vacuum pump. The invention aims to create a range of pumps of this type comprising members which exhibit a different final pressure behaviour and/or a different pumping capacities. To achieve this, the range consists of several identically constructed modules (2) of an oscillating piston pump that are connected in parallel and/or in series, according to customer requirements and each module is equipped with an oscillating piston drive.
