Flanged pumps for plant duty
Flanged ports from DN 40 to DN 125 PN 16, depending on the model, nine sizes from 120 to 1,910 cm³/rev. Versions in stainless steel are available for aggressive fluids. The NAV is the workhorse for transfer, loading and unloading of fuel and thermal oils, lubricants, diesel, solvents, resins, isocyanates, paints, soaps, chocolate and molasses.
