3. Product introduction
The DDE dosing pump is a self-priming diaphragm
pump. It consists of a housing with PMS (Permanent
Magnet Synchronous) motor and electronics, a
dosing head with double PTFE diaphragm and
valves and the control cube.
Excellent dosing features of the pump:
•
Optimal intake even with degassing media, as
the pump always works at full suction stroke
volume.
•
Continuous dosing, as the medium is sucked up
with a short suction stroke, regardless of the
current dosing flow, and dosed with the longest
possible dosing stroke.
3.1 Applications
The pump is suitable for liquid, non-abrasive,
non-flammable and non-combustible media.
Observe the technical data of the product. See
section
.
Observe the freezing and boiling points of the dosing
medium.
Make sure that parts in contact with the dosing
medium are resistant to the dosing medium under
operating conditions. See data booklet:
