Our NES MMC Cast Iron Condensate Units are built with our standard high quality bronze centrifugal pumps. Our pumps are assemblied using industry standard electric motors making our systems the best long term value in the industry. This allows our customers to easily make repairs using standard off the shelf components. The result is significant cost savings over the life of the unit. Each unit consists of a receiver tank coupled to one (simplex systems) or two (duplex systems) liquid condensate pumps.   Our cast iron receivers offer an industry leading 25 year warranty against corrosion failure.
