Strengths

Double chopping system

The first chopping system is formed by two chrome steel blades fixed to the suction part that skim over a conveyor plate in special cast iron fixed to the rotating shaft. Both materials are subjected to a specific hardening treatment. In a 1450 rpm pump, the first chopping system alone operates at a rate of 140 cuts/second!

Double chopping system

The second chopping system features a toothed plate in special cast iron which skims over an impeller, also in special cast iron, with sharp-edged blades.
Both materials are subjected to a specific hardening treatment.

High efficiency hydraulics

Hydraulics designed to combine high efficiency (up to 77% efficiency rating) and strong chopping power without clogging. Data in accordance with UNI EN ISO 9906 standards.

Double mechanical seal *

Mechanical seals in Silicon Carbide and Carbon-Ceramic

Temperature sensors

Double temperature sensors embedded in the stator to prevent the motor from overheating and ensure it continues to function correctly over time.

Humidity sensor (if requested) *

The humidity sensor is installed in the oil chamber to prevent damage should fluid leak out.

* Double mechanical seal and Humidity sensor not available for all pump versions.

Accessories

Broad range of accessories for every type of pump installation.
