DESIGN FEATURES
Innovative and reliable design. The hydraulic housing with connecting holes is made of technopolymer with metal threaded inserts. Impellers, diffusers and diffuser covers – technopolymer. Hydraulic housing, wear rings and mechanical seal flange – AISI 303 stainless steel. Mechanical seal – silicon carbide/graphite. The pumps are equipped with an air-cooled asynchronous electric motor. To ensure low noise levels and long service life, the motor shaft rotates on oversized bearings that are lubricated for life. The single-phase version has built-in overload protection. To protect the three-phase motor, overload protection must be provided in accordance with current regulations. Complies with CEI 2-3/CEI 61/69 (EN 60335-2-41).
