The Macnaught BOPHV High Viscosity Battery Oil Pump is designed for dispensing oil from five, 16, and 55 gallon containers. It's good to 140W/ISO680 oils delivering 40 gallons on a full charge at 1.5+ gpm. There is no need to use cumbersome and difficult-to-dispense hand pumps or transfer oils manually to smaller containers, the company says. Simple place the BOPHV into the container, flick the powerhead on, and engage the on-demand flow nozzle.
