The Graco EGP Electric Transfer and On-Demand Pumps are available in 115VAC or 12VDC models and are compatible with most standard electric configurations. By simply plugging the pump into a power source, an entire 55-gallon drum of 10W oil at room temperature can be emptied in less than eight minutes with the 8 gpm flow rate transfer model, the company says. The EGP pumps are ideal to use as an energy-efficient option to standard pneumatic pumps or if unable to otherwise utilize compressed air. They're engineered to last with precision gears for consistency and have a built-in inlet strainer and motor over-temperature protection to prevent overheating.
