Series DMH 250 models 251 / 252 / 253 / 254 / 255 / 257
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 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: the elaborate
combination
 |
|
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 standardised diaphragm breakage system and overpressure
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: the dosing flow can be adjusted accurately, even if
the system is not running. |
Further functions:
|
|
Any capacity
requirement between 5 and 2 x 1150 l/h can be covered without
any problems |
|
|
Especially for
applications in chemical engineering: adjustment of the dosing
flow ranges by different stroke numbers |
|
|
The number of spare parts required
is essentially reduced thanks to the elaborate modular system. |
|
|
Can be equipped with further quality
components, as electric or pneumatic servomotor, motor frequency
control, stroke frequency control, dosing head heating. |
|
|
The pump types DMH 250 models 251 - 253
are optionally available with Etron Profi electronics and
diaphragm breakage signal |
Applications:
The DMH 250 models 251 / 252 / 253 / 254 / 255 / 257 pumps offer high dosing accuracy
as well as modern interfaces for function monitoring and automatic
control and regulation. Therefore, they are made to accomplish the
demanding dosing and regulation tasks of water technology and chemical
engineering industry.
