3D VIEW Rigid shaft made of corrosion resistant stainless steel minimizes the shaft deflection < 0,05 mm : All PFA components are made through Transfer Moulding process. the design is in “dry shaft execution” where there The Transfer Moulding process is also is no contact between shaft and medium. employed for PVDF\PP casing and seal chambers. All the UCN pumps can be equipped with closed, open radial or vortex impellers in single flow, single stage execution. The suction cover is designed to guarantee a long life time even under stress, in fact it’s a lined armored piece made around a strong...
