  • PVA – Cantilever Vertical Centrifugal Pumps
Vertical centrifugal cantilever pumps

Industrial pumps suitable for pumping corrosive liquids with solids

  • Materials available: AISI 316.
  • Max flow: 24 m3/h. Max head: 26 mlc.
  • Fume labyrinth seal. A combined system of labyrinth, rings and PTFE lip seal guarantees tightness against gas and vapours.
  • Impeller with low axial thrust.
  • Suitable for corrosive liquids containing solids.
  • Especially designed for use in the production of printed circuit boards (PCB).
    AISI 316 version is suitable for potassium
    permanganate applications at 90°C.
    Titanium version is suitable for “Black Oxide”.
  • Two different types available: PVA 1 for tank transfer and PVA 2 used as a boosting pump.
    PVA 2 model should be installed in the same tank where PVA 1. This provides a tight system which prevents any leaks.
