Pumps quickly evacuate tanks for fast-turn product switchovers

December 8, 2009
The sliding vane pumps have the unique capabilities to quickly and efficiently evacuate product from large liquid storage terminals, according to the manufacturer. High capacity pumps handle large volumes of non-corrosive liquids, from thin solvents to heavy oils and molasses. Strong suction lift capability efficiently transfers these products from barge or ship into storage tanks while efficiently stripping both suction and discharge lines to minimize product loss. Self-adjusting vanes eliminate slippage caused by normal wear, thus maintaining flow rates. The pumps are also self-priming so they are always ready to operate. An internal relief valve protects against excess line pressure. A major benefit of the pumps is significantly reduced maintenance versus other pumping technologies. The pumps are available in 6, 8 and 10-inch ANSI flanged port sizes with operating speeds up to 350 rpm and maximum rated capacities of 755, 1228 and 2300 gpm. The ductile iron pumps can be powered with a standard electric motor or diesel engine through a commercial gear reducer.
