The seal cover, motor casing, cover and handle are made of stainless steel. The pump body and the base are made of cast iron. It’s fitted with dry, asynchronous and waterproof motor, cooled by the pumped liquid. Rotor running on permanently lubricated ball bearings, oversized and selected to ensure low noise and durability. Thermal-overload protection provided as standard for the single-phase version, while the three-phase version has thermal protection that can be connected to a control panel.
