Husky 3300 Air Operated Double Diaphragm Pumps
About Husky 3300 Air Operated Double Diaphragm Pumps
HUSKY 3300 SERIES
OVERVIEW & FEATURES
Dual Drive Performance: 3-inch pump platform available in pneumatic (stall-free, low-pulsation) or electric (up to 80% energy savings) configurations.
Class-Leading Flow: Highest flow rate in its class, delivering up to 300 gpm (pneumatic) or 220 gpm (electric).
Extended Life: Overmolded diaphragm designs offer up to 5× longer life; seal-less architecture eliminates mechanical seal failures.
Versatile Handling: Self-priming and run-dry capable; safely transfers slurries, abrasives, and shear-sensitive materials with solids up to 1/2 inch.
Control & Safety: Electric models are VFD-compatible for metering/process control with near-zero noise pollution; ATEX configurations available.
Rugged Construction: Heavy-duty build with a one-piece center section to reduce leak points; ANSI-compatible porting for drop-in replacement.
