1. General description
The GRUNDFOS DMS 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 and
•a control panel incorporating display and
buttons.
The pump is fitted with a synchronous motor, which
is started and stopped by means of the integrated
electronics. The capacity is varied by changing the
stroke frequency. The pump always generates a
complete stroke with full stroke length and the speed
of the suction and dosing strokes is constant, irre-
spective of the capacity setting. The motor drive also
eliminates undesired peak values during the suction
and dosing strokes. 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 1:100.
The pump features an LCD display and a user-
friendly control panel which gives access to the
pump functions.
1.1 Applications
The DMS dosing pump is designed for handling
chemicals within the following ranges of applications:
• Drinking water treatment.
• Wastewater treatment.
• Swimming pool water treatment.
• Boiler water treatment.
• Cooling water treatment.
• Process water treatment.
• Washing systems.
Before beginning installation procedures,
these installation and operating instruc-
tions should be studied carefully. The
installation and operation should also be in
accordance with local regulations and
accepted codes of good practice.
