VX 8/35-ST - 0.75 HP three-phase VORTEX electric sewage pump
Flow rate up to 350 l/min (21 m³/h). Head up to 9.5 m. 0.55 Kw (0.75 HP) motor.




The VX 8/35-ST submersible electric pump from the VX-ST series by Pedrollo stands out for its power and performance.
High performance and efficiency are possible thanks to the hydraulic geometry of the volute and the VORTEX impeller.
The VORTEX impeller allows the passage of solid bodies with a diameter of up to 40 millimetres and, thanks to its geometry, guarantees safe operation against clogging.
The VX 8/35-ST is recommended for draining flooded areas, emptying cesspits and disposing of sewage.
Built entirely of stainless steel, it is characterised by particular resistance to corrosion and abrasion.
