Calpeda Single Phase Easy Mat Pump – 60Hz
Call for Price
Construction
Variable speed system driven by frequency converter, for the pressure control in domestic and residential plants. The system is connected to the delivery pipe providing for simple installation and better cooling (patented) making the unit more compact and easy to assemble. Easymat is supplied with one pressure transducer,G 1/4connection and 1.5 m cable length.
Easymat is equipped with a control panel for simple system programming and parameter monitoring.
Applications
Automatic frequency inverter control for use on pumps to increase network pressure. The system maintains constant pressure whilst the controlling the pump operation against changing system demand.
For protection of the pumps:
–Against dry running
–Against operations with closed connection ports
–Against overcurrent of the motor
–Against overvoltage and undervoltage of the power supply
Features
- Constant pressure
The easymat via a frequency inverter keeps the pressure constant as the flow demand changes.
- Energy saving
The variable speed operation ensures that only the energy required by the plant at any instant is used.
- System reliability
Because the easymat is independent of the pumped liquid it's operation is not affected by fluid impurity. A float switch can also be integrated to further protect against dry running.
- Flexibility
Thanks to it's patented design the easymat does not come into contact with the pumped fluid. This provides for more flexibility during installation eliminating the need for pipe-work modifications or the installation of isolating valves.
- Easy to use
The easymat has a clear display making it very simple to set-up.
- Cascade control mode
The system flexibility allows via a microprocessor for cascade operation of three easymat's via one pressure transducer.
