3D VIEW Rigid shaft made of corrosion resistant stainless steel minimizes the shaft deflection < 0,05 mm : the design is in “dry shaft execution” where there is no contact between shaft and medium. The bearing frame can be equipped with 3 different type of • CSS-35 Single mechanical seal • CDC-35 Double cartridge mechanical seal • Single-acting and double-acting mechanical seals configuration, also on cartridge execution All PFA components are made through Transfer Moulding process. The Transfer Moulding process is also employed for PVDF\PP casing and seal chambers. All the UCL pumps can be equipped...
