Страница: 8 / 44

2. General description
The Grundfos DME dosing pump is a self-priming
diaphragm pump.
The pump consists of:
•
a cabinet incorporating the drive unit and
electronics,
• a dosing head with back plate, diaphragm,
valves, connections and vent valve,
• a control panel incorporating display and
buttons. The control panel is fitted either to the
front or to the side of the cabinet.
The motor is controlled in such a way that the dosing
gets as even and constant as possible, irrespective of
the capacity range in which the pump is operating.
This is carried out as follows:
The speed of the suction stroke is kept constant and
the stroke relatively short, irrespective of the capacity.
Contrary to conventional pumps, which generate the
dosing stroke as a short pulse, the duration of the
dosing stroke will be as long as possible. Thus, an
even dosing without peak values is ensured. As the
pump is always dosing at full stroke length, it ensures
the same high accuracy and suction capability,
irrespective of the capacity, which is infinitely variable
in the ratio of 1:800.
The pump features an LCD display and a user-
friendly control panel which gives access to the pump
functions.
