Submersible pumpsPEDROLLO VX 8 35 Submersible
Pumps

※ The Go-To Pump for Demanding Conditions and Performance Requirements

PERFORMANCE RANGE

  • Flow rate up to 750 l/min (45 m3/h)
  • Head up to 15.5 m

INSTALLATION AND USE

VX pumps are renowned for their reliability, especially in automated fixed installations.

Ideal for domestic, civil, and industrial settings, they efficiently handle suspended solids up to 50 mm in diameter,  including in groundwater, surface water, and sewage.

They are also perfect for pumping out flooded areas like basements, underground parking garages, car wash stations, and emptying septic tanks and sewage systems.

※ The VORTEX impeller can handle solids up to 50 mm in diameter. Its unique design ensures safe operation  against clogging.
