UCL – plastic lined mechanical seal
Single-stage, mechanical seal centrifugal process pumps lined with plastic and fluoroplastic materials. Available materials: PP (polypropylene), PVDF (polyvinylidene fluoride), PFA (perfluoroalkoxy). Long coupled (UCL) and close-coupled (UCL-B) execution.
Versatility: Suitable for pumping corrosive, aggressive and hazardous liquids (slightly contaminated, clean, low viscosity) in the chemical, petrochemical and pharmaceutical industries.
Reliability: Various mechanical seals can be installed on UCL pumps. A redesigned bearing support ensures a longer service life even under critical service conditions.
Design: UCL pumps have the same hydraulics as the UTN magnetic drive series, process pumps for the chemical industry.
