UCN-L Centrifugal Pumps with Mechanical Seal

Plastic and Fluoroplastic Lined Process Horizontal Centrifugal pumps with Mechanical Seal Lining:
– PP (Polypropylene)
– PVDF (Polyvinylidene fluoride)
– PFA (Perfluoroalkoxy)

End-suction – Long Coupled (UCL) and Close Coupled (UCL-B) execution

Versatility: Suitable for handling corrosive, aggressive and hazardous liquids (low viscosity, clean or slightly to dirty contaminated) in the chemical, petrochemical and pharmaceutical industries.

Reliability: The UCL offers a wide range of shaft sealing and the pumps are also equipped with reliable bearing bracket, especially developed to be suitable even under heavy duty service.
