Magnetic-drive pumps

Horizontal and vertical centrifugal pumps

UCN-L are single-stage horizontal centrifugal pumps with conventional mechanical sealing system.
Connected to the driving part by means of a spacer coupling (back pull-out version) and installed on a common baseplate, their design is fully compliant with standards DIN 24256 and ISO 2858. The corrosion-resistant plastic lining of the pump casing is produced by moulding thermoplastic resins such as PP and PFA directly onto the suitably-machined metal casing (CDR ILS - Integrated Lining System - technology) thus obtaining pumps providing exceptional resistance to even the severest forms of chemical attack and mechanical stress. This moulding technique means that UCN-L series pumps can work with operating temperatures of up to 120°C and pressure of up to 16 bar. UCN-L series pumps can mount various types of single, double or cartridge mechanical seals of the top domestic and international brands, along with the standard CDR FC 35 seal that has been specially designed to work with corrosive liquids containing suspended solids and/or crystals. Generously-sized shaft and bearings, closed, open or open vortex impeller with reduced overhang and exclusive CDR locking system and tapered stuffing box with abrasion-resistant flow-regulating baffles make this series of Hi-Tech pumps ideally suited for the most demanding process services.

These pumps are typically used in all industrial sectors for the transfer of liquids, in particular: corrosive liquids, slurry, liquids containing crystals, dirty liquids, effluents and chemical wastewater.
