Trust the CRN for corrosion-resistant reliability
The CRN pump is an in-line, multi-stage pump available in a wide variety of flow and pressure sizes. Built from high-grade AISI 316 stainless steel, the CRN is perfect for ultra-filtration, reverse osmosis, machine tools (cooling lubricants), distillation systems, swimming baths, oils, alcohols, acids and alkalis, process-water systems and processes handling a broad range of problematic liquids.
A number of ATEX-approved CRN pumps are available, according to the locality, hazard and likelihood of a dangerous situation occurring. ATEX-approved pumps are for use in potentially explosive atmospheres. Explosive atmospheres consist of air and combustible matter such as gases, vapours, mist or dusts in which the explosion spreads after ignition.
