Piston diaphragm dosing pumps DMH 280 models 280 / 281 / 283 / 285 / 286 / 287 / 288 series

The optimum capacity graduation between 0.63 and 2 x 222 l/h makes this series of extra-rugged dosing pumps stand out. Three drive sizes, as well as versions with a single or double dosing head are available.

All models are equipped with universally resistant full Teflon diaphragms, in addition to the patented ALLDOS diaphragm protection system AMS, and a vernier scale with a very fine graduation. A variety of options are available, e.g. electric or pneumatic actuators, frequency motor control, special dosing heads or a double diaphragm system with breakage signal.


Features and Benefits:

  • High dosing accuracy and exact reproducibility of the dosing flow. The deviations in dosing flow constancy and linearity are below 1%.
  • The pumps can be universally employed due to the full Teflon dosing diaphragm and optimum material combinations of the parts in touch with the media.
  • Very easy adjustment of the dosing flow; the dosing flow can be adjusted accurately, even if the system is not running.
  • For use of applications in chemical engineering, the dosing flow ranges can be adjusted with different stroke numbers.
