CANTILEVER
Thanks to the absence of submerged components such as bearings and bushings, cantilever pump enables the pumping of a large variety of liquids with or without suspended solids, including abrasive ones, without the need for external lubrication.
The pump primes automatically when the liquid covers the impeller, allowing it to operate even without minimum level controls. The use of the suction pipe allows tanks up to a depth of 5 meters to be emptied.

• Closed impeller
Available on demand.
Modularity
• Dry running.
• No minimum level control.
Efficiency
• Low maintenance costs.
