Piston diaphragm dosing pump DMH 250 models 251 / 252 / 253 / 254 / 255 / 257 series

The optimum capacity graduation between 5 and 2 x 1150 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, such as 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 2%. 
  • High degree of functional safety by standardized diaphragm breakage system and over-pressure valve.
  • 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; can be adjusted accurately, even if the system is not running.
