Example of an order
A solenoid metering pump controllable by water meter
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
provided.
Pump selection
a ) Based on the flow rate of 0.4 ml/stroke, the
MAGDOS 4 is determined according to the
performance curve (MB 1 02 20/6). Because of the
required warning alarm relay, the control unit of
pump type DE4S, Part No. 33942, must be chosen
from table 2.
b ) Select drive Part No. 32720 from table 1.
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.
