The medium to be pumped is squeezed behind lhe diaphragm by lhe pneumatics and ihus pumped, whereby lhe diaphragm serves only as a separator. The diaphragms are always equally loaded and are Iree of any pressure differences. This is of decisive importance lo lhe life span of the diaphragm. The suction and discharge volves can be manufactured as ball or cylindrical cocks. | | |
