Mechanical speed adjustment for metering pumps

Published:  03 February, 2014

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.

Wanner says because Hydra-Cell pumps are true positive displacement pumps, flow rate is directly proportionate to input shaft rpm and virtually independent of system discharge pressures. Very precise and repeatable, infinite adjustment of shaft speed can be achieved from almost zero rpm, through a simple manual adjust hand wheel. It transmits its highest torque from speed zero, is adjustable in operation and at rest and exhibits linear setting characteristics. The Wanner mechanical speed variator is said to be ideal for use in explosive environments.
