General
MAGDOS DE / DX solenoid metering pumps combine
the digital technology of state-of-the-art
microprocessors with high-quality mechanics. Due to
its versatility in the area of external control, the new
MAGDOS series is very flexible. The pump can be
supplied with a digital display upon request. The display
shows the different operating conditions and possible
error messages.

The new MAGDOS is available in two basic versions
with the following features:

MAGDOS DE
-   Internal control with continuous stroke frequency
    adjustment from 0 to 100 strokes per minute for
    DE 01...12 and 0...70 strokes per minute for
    DE 20...100
-   Changeover function to external pulse control by
    water meter or other voltage-free contacts
-   Connection for level control with alarm signal

MAGDOS DX
-   Internal control with continuous stroke frequency
    adjustment from 0 to 100 strokes per minute for
    DX 01...12 and 0...70 strokes per minute for
    DX 20...100
-   Changeover function to external control by
    0/4...20 mA standard signal
-   Changeover function to external pulse control by
    water meter or other voltage-free contacts

c) Standard signal 0/4...20mA
To control the pump by standard signal 0/4...20 mA,
operate the selector switch. The linearity of converting
the signal into stroke frequency is +/- 3%. If the signal
source is not isolated, it must be ensured that the signal
line does not come into contact with ground (separate
isolators available upon request!).
Note: To avoid accidental metering after the process
is finished, provide an electric or hydraulic interlocking
system.

Example of an order                                                       Place the order as follows:
A solenoid metering pump controllable by water meter                      MAGDOS DE 4 S consisting of:
contacts is required for metering 0.4 ml phosphate per
stroke against 8 bar. For remote monitoring from a
central control station, a warning alarm relay is to be                       1 Drive                            32720
provided.
                                                                              2 Control unit                     33942
Pump selection
a) Based on the flow rate of 0.4 ml/stroke, the                               3 PVC metering head                23809
   MAGDOS 4 is determined according to the
                                                                              4 PVC suction valve                20890
   performance curve (MB 1 02 20/6). Because of the
   required warning alarm relay, the control unit of                          4 PVC discharge valve              20891
   pump type DE4S, Part No. 33942, must be chosen
   from table 2.                                                              5 Suction connection 4/6           20975
b) Select drive Part No. 32720 from table 1.
                                                                              5 Discharge connection 6/12        32980
c) Part No. 23.809 is chosen as metering head (PVC
   is compatible with phosphate).
d) For the suction and discharge valves, select Part
   No. 20.890 and No. 20.891 (PVC and Viton are
   resistant).
e) See table 5 for suction connection Part No. 20975
   for ø 4/6 tubing and discharge connection Part No.
   32980 for ø 6/12 tubing.
f) The suction line, preferable with level control, can
   be found in MB 1 22 01.
