STN – plastic magnetic drive
Compact horizontal centrifugal pumps with magnetic drive in plastic and fluoropolymer materials.
Reliability: suitable for pumping corrosive, aggressive and hazardous liquids (slightly contaminated, clean, low viscosity) for chemical industries.
Design: made with the same reliability as the ETN, but for smaller applications or where operating conditions are less critical and discontinuous.
The STN range is capable of reaching temperatures up to +70°.
Available in monobloc execution.
