The J self-priming centrifugal pumps are used in applications requiring a fast priming capacity from demanding suction heights combined with the ability to transfer and manage polluted, waste and abrasive fluids with suspended solids.
The system features an inspectable pump casing, which also acts as a water tank allowing for early quick priming without auxiliary systems, simplifying system management and reducing maintenance times.

PSDrive® - Variatore di frequenza

Varisco PSDrive può essere installato direttamente a bordo motore al posto della basetta motore delle pompe JE…NT Varisco garantendo:

  • Risparmio energetico ed economico
  • Ampliamento delle possibilità di prestazione delle pompe autoadescanti
  • Riduzione dei tempi d’innesco
  • Versatilità in caso di contenute modifiche d’impianto, di prestazioni richieste e di fluido pompato

PSDrive può essere gestito e monitorato anche da remoto tramite la comoda App Varisco PSDrive disponibile per Android e iOS.
