Our Husky™ 515 and 716 diaphragm pumps are ideal for evacuating 55 gallon (208 liter) drums since they are free of rotating parts. These transfer pump packages can handle abrasive and shear sensitive fluids up to 5,000 cps with flow rates up to 16 gpm (61 lpm). The suction tube length can be adjusted from 31.5 inches to 34 inches (80-86 cm) with our easy out-seal assembly, making sure that our pumps will fit the height of your drums.
