STRUCTURAL CHARACTERISTICS
Motor: three-phase squirrel cage type, windings from 6 to 12 poles, IP 68 protection degree, insulation class F = 155° C, service factor S1, with a max of 15 startings per hour.
Motors are also available at different tensions and frequencies.
Motor cooling: by surrounding liquid 
Shaft: made of stainless steel, widely dimensioned, supported by life-lubricated ball bearings.
Shaft seal: double mechanical, realized in silicon carbide in order to allow the maximum resistance to abrasion.
Infiltration monitoring: by water probe into the oil chamber for the timely warning of possible infiltration through the shaft seal.
Temperature monitoring: by thermal sensor into the winding, which warns or stops the pump in case of
motor overload.
