Mechanical speed variators
27 August 2013
Wanner International has introduced a range of mechanical speed variators for manually adjusting the rotational speeds and output flows of its Hydra-Cell metering pumps.

These pumps are used in oil and gas production for injecting chemicals such as acids and bases, amine gas sweeteners, oxygen scavengers, polymers and proprietary chemicals into process streams.
The Wanner mechanical speed variator is suitable for use in explosive environments and is ATEX certified for zones 1 and 21, completely removing the need for complex and costly external ATEX control.
