PumpDrive 2 Eco
The use cases in the application guide are only typical examples for training purposes. The examples are not cus-
tomer specific solutions. The examples are not binding and can be incomplete. The examples do not cover all possi-
ble eventualities. The examples do not cover all design details and variants, nor do they cover all scenarios and situ-
ations that may arise during installation, operation or maintenance. The application guide is not replacing the oper-
ating manual. In any case of divergence the operating manual has higher priority. The operator must take care
about the appropriate operation referring to the operating manual. The examples do not excuse from the save op-
erating, installation and service. Changes of this application guide will be done without announcement.

Retrofit PumpDrives, which will be selected in EasySelect, will be delivered only with motor data (work is in progress). The pump curves
must be parameterized on site, can be uploaded from PumpMeter, can be set from ServiceTool or display.
PumpDrives (spare parts), which are ordered by material numbers are not parameterized in the production.
Using a 0/4…20mA or 0/2…10V Sensor for control a PumpMeter can be used as internal sensor in parallel. PumpMeter used as internal
sensor improves the flow estimation.

A fixed speed of 2000 1/min should be given by an external signal 4…20mA at analog input 1.
The feedback of the speed should be send by analog output to a PLC.
2000 1/min is equal to 14,85 mA when using a 2-pole motor with a nominal speed of 2950 1/min (16mA / 2950 rpm * 2000 rpm + 4 mA

A constant differential pressure of 4 bar is needed. The 4…20mA differential pressure sensor with a measurement range of 0-6 bar is
connected to analog input 2. The set point is given via analog input 1 by a voltage 0…10V signal. The set point is 4 bar is equivalent to

2.2.5 Closed loop control: Sensorless differential pressure control
A constant differential pressure of 4 bar is needed without using a sensor. The set point is given by the display. The procedure is based on
the characteristic curves of the pump. Steep power curves are conducive to high process accuracy. The process is suitable to a limited
extent if sections of the power curve are constant over the flow rate. To facilitate sensorless differential pressure control, all parameters
of the pump characteristic curves (3-4-1, 3-4-3-1 to 3-4-3-22) and the pipe diameters (3-5-2-1 und 3-5-2-2) must be entered. All needed
parameters for the flow rate estimation like pipe diameters are preset in the pump production when ordering a completely assembled
pump, motor and drive.
