The ESPA Silen Plus 1 pump is equipped with a frequency inverter that automatically adapts the motor speed to the current flow requirement. Compared to conventional single-speed pumps, it thus achieves significant savings in electrical energy – in low-pressure modes, consumption drops to a fraction of the nominal power input.
The integrated wireless ESPA EVO pool control system senses the position of the six-way valve and, based on this signal, automatically activates or deactivates the relevant working cycle of the pump. The result is fully automated filtration operation without the need for manual intervention.
The flow of 7 to 21 m³/h and the 230 V power supply predestine this pump for medium-sized private pools. Thanks to its compact dimensions and quiet operation, it is also suitable for installations near living spaces.
