RPR-CONTROL-100
ELECTRONIC PROTECTION
is the efficient monitoring system for
centrifugal pumps of up to 20kW.
Electronic monitoring of motor currents
protects the pump from dry running,
overheating and overload.
If the above mentioned operating states
are not absolutely impossible with your installation,
you should use an electronic process monitor to switch
off the pump before it is damaged. Such monitors will
not only avoid damage to the pump, but also downtime
and costs resulting thereof. At the same time, the monitor
checks the pumping process for the set delivery rate.
Once the cause of a malfunction is eliminated, the pump
is immediately ready to continue operation. The process
monitor is easy to install into the pump’s power
supply unit. As it is not necessary to build it into
pipe runs, this process monitor also is ideal to retrofit
existing installations. Four different types of process
monitors are available:
|
|
|
RPR CONTROL 100-1
to be built into control cabinets
(mounted on top-hat rail)
without programming unit.
RPR CONTROL 100-2
to be built into control cabinets
(mounted on top-hat rail)
with integrated programming unit. |
 |
RPR CONTROL 100-3
Field device with power section of up to 4.0 kW
(up to 7.5 kW optionally available),
mounted in an IP 65 casing for installation in the field
(e.g.at the filter), complete with indicating lamps and push-button but
without programming unit. |
 |
SEPARATE PROGRAMMING
UNIT
Hand-held appliance with cable and plug to programme
the switching thresholds of RPR-Control 100-1 and RPR-Control
100-3. |
FUNCTION
An overload controller with analogue output monitors
the actual
power of the pump motor. There are four switching thresholds defined:
• dry-running (fault, the motor is switched off);
• overheating (fault, the motor is switched off);
• overload (fault, the motor is switched off);
• filter contaminated (warning).
The switching thresholds are user-programmable.
Also included is a real-time clock with elapsed-time meter, e. g. to
monitor maintenance intervals.

PUMP WITH EXTRA PRIMING TANK |
 |
All non-self-priming pumps of the RM type may be combined
with an extra priming tank to be self-priming as well.
SONDERMANN supplies you with the whole installation
completely mounted to a base plate.
Priming tanks are available in different sizes ranging
from 5 to 50 litres. When arranging the design, make
sure that the volume of the priming tank is about 1.5
times larger than the overall volume of the suctionpipe
runs to be evacuated.

PUMP WITH INTEGRATED FREQUENCY CONVERTER |
 |
IF SEVERAL DELIVERY RATES ARE REQUIRED
SPEED CONTROL IS USED TO PRECISELY SET THE OPERATING
POINT DESIRED.
Features:
- Power ranges: 0.37 to 1.1 kW
-
Voltage: 230 V single-phase, 50
or 60 Hz
-
The speed rate is set either by
a signal of an imposed control unit or by the control
panel mounted to the motor.
-
The frequency converter is perfectly
tuned to the characteristic of the pump.
-
This operating principle saves much
energy in contrast to adjusting delivery rates by
means of flow-control valves.

| FLOW
MONITORS
|
 |
FOR SIMPLE AND COST-EFFECTIVE MONITORING
Characteristics:
-
The housing is made of polypropylene
or PVDF. Flow monitors are to be built into the discharge
pipes of magnetically coupled centrifugal pumps of
types 2 to 4.
-
Every flow monitor has an integrated
float switch and a reed contact. A spigot nut at the
inlet side of the flow monitor is used to screw it
to an external thread with O-ring sealing.
-
The outlet side of the flow monitor
is equipped with a grooved external thread to take
the O-ring seal.
-
The necessary O-rings are optionally
available.
-
When ordering a flow monitor, please
indicate the
density of the fluid delivered.
