VX VORTEX
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.
