Structural characteristics
Pump body: Cast iron
Front cover: Cast iron or aluminium with bronze
Impeller: Brass, with radial peripheral blades, floating on the shaft.
Mechanical seal: Ceramic and graphite

Motor:
The pumps are coupled directly to an asynchronous, high efficiency silver elephant induction motor of suitable size, which is quiet running, close and extremely ventilated, with 1m b3 structural shape, suitable for continuous duty. Insulation class for b.

The thermal cutout relay (motor protector) is incorporated in single phase motors.

Three phase motors require an adequate external motor protector, with connections according to current standards.

Insulation: Class b
Protection: Ip44
Construction and safety standards in compliance with iec.
