Embodiment Construction

[0056] figure 1 is schematically showing the structure of the diaphragm unit 1 installed in the diaphragm pump.

[0057] The membrane unit 1 has a membrane core 2 which, in the exemplary embodiment shown, is constructed in two parts. The diaphragm core 2 has a threaded hole 3 as a receiving means for a push rod 4 . In the installed state of the diaphragm unit 1 , the diaphragm core 2 is connected to the drive of the diaphragm pump by means of a push rod 4 . According to the present application, the push rod 4 is not an integral part of the diaphragm unit, so that in the event of rupture or other failure of the diaphragm of the diaphragm unit, only the diaphragm unit 1 can be replaced without replacing the push rod 4 .

[0058] Also important for the diaphragm unit is the multilayer pump diaphragm 5 connected to the diaphragm core 2 .

[0059] exist Figure 1 to Figure 3 In the embodiment, the pump diaphragm 5 consists of three layers respectively. A fluid-tight working di...

Abstract

The present invention concerns a diaphragm unit for a diaphragm pump comprising a diaphragm core having a receiving means for a thrust rod of a pump drive, and a multi-layer pump diaphragm connected to the diaphragm core, wherein the pump diaphragm has a fluid-impermeable working diaphragm layer which in operation of the diaphragm pump comes into contact with a fluid to be delivered by the diaphragm pump, and a fluid-impermeable safety diaphragm layer, a sealed volume for receiving a fluid passing through the working diaphragm layer, that is arranged between the working diaphragm layer and thesafety diaphragm layer, and a first clamping region with which the pump diaphragm can be received in a receiving means of the diaphragm pump, wherein the first clamping region forms a ring which annularly surrounds the diaphragm core. To provide a diaphragm unit for a diaphragm pump which in a simple fashion permits detection of a rupture of the working diaphragm layer, according to the inventionit is proposed that provided within the ring formed by the first clamping region is at least one element of a sensor for detecting a fluid which penetrates into the sealed volume of the pump diaphragm.

Description

technical field [0001] The invention relates to a diaphragm unit for a diaphragm pump, comprising: a diaphragm core having a receiving device for a push rod of a pump drive; and a multilayer pump diaphragm, said multilayer pump diaphragm connected to a diaphragm core, wherein the pump diaphragm has: a fluid-tight working diaphragm layer in contact with the fluid to be delivered by the diaphragm pump during operation of the diaphragm pump; and a fluid-tight safety diaphragm layer a sealed volume for receiving fluid passing through the working diaphragm layer, said sealed volume being arranged between the working diaphragm layer and the safety diaphragm layer; and a first clamping region through which the pump diaphragm can be received In a receiving device for a diaphragm pump, wherein the first clamping area forms a ring annularly surrounding the diaphragm core, such that an annular area is provided between the first clamping area and the diaphragm core, said annular area is a...
