This is a 3-inch high-flow helical gear pump from the industry-standard 3600 series with a displacement of 32 gallons per 100 revolutions, featuring flanged NPT ports with outboard bearing and single internal relief valve. This compact, heavy-duty pump operates efficiently in both directions and effectively handles heavy, viscous materials such as asphalt, molasses, roofing compounds, and printing inks, as well as fuel oils and gasoline. Built with cast iron gears, bronze bearings, and precision-ground steel shafts for maximum durability in petroleum transfer and tank truck applications. Designed for faster tank turnover with higher viscosity handling capabilities than standard 3600 series models.
