They can deliver thin to highly viscous liquids, as well as corrosive and solids laden chemicals. The repeatable accuracy has ≤ 1% fluctuation. Available in five (5) capacities and three (3) pressure ranges, flow rates range from 0.1-1,000 l/h at 6, 12 or 24 bars differential pressure.  \nThe modular construction of the group D pumps allows easy change-out of the rotor, stator and other wetted parts.
