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 single or double dosing head are available.
All models are equipped with universally resistant full teflon diaphragms as well as with the patented ALLDOS diaphragm protection system AMS and a vernier scale with a very fine graduation. A variety of options is available, e.g. electric or pneumatic actuators, frequency motor control, special dosing heads or a double diaphragm system with breakage signal.
Reliability and accuracy guarantee optimum process safety:
||High dosing accuracy and exact reproducibility of the dosing flow. The deviations in dosing flow constancy and linearity are below 1%.|
||High degree of functional safety by standardised diaphragm breakage system, overpressure valve and vent valve of the hydraulic system.|
||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.|
||Especially for applications in chemical engineering: adjustment of the dosing flow ranges by different stroke numbers|
