    摘要: A measuring gas pump (1) including a pump housing (2) with a pump chamber (3) inside which is sealed by a working membrane (5). The membrane (5) is connected: by a connecting rod (8) or a similar type of lifting device to a crank mechanism (9). A heating device is provided in the upper area of the pump housing, specifically in the pump head (10). On one hand, in the drive-transmission area between the head of the connecting rod (6) on the membrane side and the crank mechanism (9), there are holes (11) for the reduction of heat transfer to the crank mechanism which are spaced in a longitudinal direction of the connecting rod and which are also diametrically opposed, in peripheral direction, with a resulting reduction in heat conductivity. On the other hand, there is an enlargement of the surface area, at least in the area adjacent to the crank mechanism, for purposes of heat dissipation, specifically through cooling ribs (12).

    摘要: A vacuum pump stand (1) for generating and regulating the vacuum intended for a rotary vaporizer, including a control device having a control connection to a control unit (4) having at least one control element (3, 6). In the pump stand (1), the control unit (4) is designed as a remote control unit having a wireless control connection to the control device of the pump stand. Laboratory personnel can thus observe the rotary evaporator and the associated pump stand (1) through the divider of a fume cupboard, in order to be able to modify and readjust the process parameters at the remote control panel as needed. Because the remote control unit (4) has a wireless control connection to the control device of the pump stand (1), the fume cupboard no longer needs to be opened, even momentarily. Rather, the pump stand (1) can be operated from a sufficient distance outside the fume cupboard without the laboratory personnel needing to be exposed to special hazards.

    摘要: A multi-stage diaphragm suction pump, comprising at least two pump chambers, each having a fluid inlet having at least one inlet valve, and a fluid outlet having at least one outlet valve, and a suction line, which connects the fluid inlets of the pump chambers. Consecutive pump chambers are connected to each other by at least one connection line such that, when a differential pressure in the suction line is reached/exceeded, the diaphragm pump changes from parallel operation of the pump chambers thereof to an operating mode of the pump chambers that is at least also serial. At least one check valve, which opens to the downstream pump stage, is interposed in each of the inflow and outflow regions of the at least one connection line. In order to optimize the pump characteristic of such a diaphragm suction pump, at least in one pump chamber, either in order to improve the intake pressure the suction-side opening of the at least one connection line, or in order to improve the suction capacity the pressure-side opening of the at least one connection line, is disposed in the region of the pump chamber, or in the vicinity of the region of the pump chamber, on which the diaphragm associated with said pump chamber rolls off first during a pump cycle. In addition, or instead, according to a further embodiment at least one connection line, in particular between successive pump chambers, has a descending line progression and, for this purpose, compared to the outflow-side line segment, the inflow-side line segment of the at least one connection line is arranged at a higher level.
