Hydrovar

1. When the pump doesn’t run for a long time can the Hydrovar protect against ceasing?
The Hydrovar starts an automatic test run of the pumps to avoid ceasing after a long period of no operation – the time interval is programmable.
2. What types of motors can be used with the Hydrovar unit?
Hydrovar units can be effectively mounted on all available standard three phase asynchronous motors for centrifugal pumps or fans.
3. Where is the difference between a standard frequency converter and the Hydrovar unit?
The Hydrovar hardware and software is especially developed for pumping applications and so the parameters you can program are optimal for this.
4. Is it necessary to maintain the Hydrovar in periods?
The Hydrovar control unit does not require special maintenance.
However, the cooling fan and the vents should be freed of dust occasionally.
5. Can the Hydrovar unit check any failures in the application?
Hydrovar have a built in delivery control protection logic. In case the pressure sensor finds that there was not enough pressure built up after a certain time of operation it switches off and tries again up to a max. of five times.
This avoids dry running of the pump and running out of the curve.
6. How is the scope of the Hydrovar and which applications are possible?
Besides the standard pressure or differential pressure control according to a constant set value, Hydrovar’s microprocessor is able to follow a defined curve (i.e. pipe- work characteristic) without additional devices or control units.
7. Is it possible to use the Hydrovar for multipump systems?
In multipump units each Hydrovar is able to communicate with up to seven more Hydrovar units following the actual demand of the system without additional control units.
8. How is the speed of the pumps split in a multipump system?
In multipump systems you can take the MULTICONTROLLER Mode (one pump with max. speed and the following with the required speed or a special feature (SYNCHRON CONTROL) allows all operating pumps to run at the same speed – the total system demand is split up in equal portions to each operating pump.
