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.
