Speed adjustment

The pumps are used in oil and gas production for injecting chemicals into process streams. As 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 is 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 speed variator is suitable for use in explosive environments and is ATEX certified for zones 1 and 21.
