Metering pump for metering aggressive media

摘要

A metering pump for metering water with aggressive media to be metered is produced. In this case, it is to be brought about that the pump is no longer corroded by the aggressive medium to be metered. The metering pump (1) has a storage container (2) which encloses a flexible bladder (18) which receives the aggressive medium to be metered and has an outlet (17) which can be connected to the metering point (16). The flexible bladder (18) is surrounded by a compression-proof housing (3). The interior of the compression-proof housing (3) surrounding the flexible bladder (18) can be acted upon with a non-aggressive pressure medium such as water via a pump (6). <IMAGE>
