There is also no need to detach the transmitter or its tubes. If it is desired that no seal water enters the process, the pressure of the seal water is then set lower than that of the liquid being pumped. Voltages: Enclosure: Insulation class: Max. In order for both to obtain the same operating hours, the units must alternate e. Operating principle The adjustment, control, measurement, indication and alarms of the pump frequency converter is carried out externally using building automation, process control, or by means of MODBUS RTU bus functions. Selecting a pump for frequency converter operation with one unit running with a maximum frequency of 50 Hz or 60 Hz. Used in c refrigeration systems when the temperature is below 0C.

Pump curve The QH curve of the pump is horizontal, which is applicable for circulation systems where the pressure loss of the heat source is low in relation to the total pressure loss. Juan David Valderrama. Related titles. Jump to Page. In Finland, the pumps are delivered in red, colour RAL

|Then, remove the grease with a dry and clean cloth.
If required, you can lightly tap the impeller with a rubber mallet until flush with the ridge. Service and spare parts The pump does not require regular service. In the parallel operation of two units, the flow of the twin pump is double compared to flow using one unit at the same pump head. It makes it easier to set frequency converter parameters if the positioning of the pump makes it difficult to see the keyboard, for example.

The position of the motor unit and therefore the location of the frequency converter box can be changed by detaching the motor unit from the pump housing and turning it to the required position, within certain limitations. Constant differential pressure is maintained over the inlet and outlet lines of the system, and is set to Parameter of the frequency converter as percentages of the maximum measurement value of the differential pressure transmitter mentioned in the transmitter.
The pressure is set to Parameter of the frequency converter as percentages of the maximum measurement value of the differential pressure transmitter found in the pressure transmitter. The QH curve of the pump is horizontal, which is applicable for circulation systems where the pressure loss of the heat source is low in relation to the total pressure loss.
Minimum frequency curve is 20 Hz.

|The NPSHavvalue of a system refers to the actual difference between inlet pressure in the suction flange and vapour pressure of the liquid being pumped. An example of selecting a pump: Duty point 5. Accessories Pump and frequency converter.
Find a pump size with a BEP best efficiency point which is as close as possible to the required duty point. Selecting a pump for frequency converter operation with one unit running with a maximum frequency of 50 Hz or 60 Hz. Inacio Costa. Utpal Mondal.
