Pump-Out Drum-Top Vacuum Cleaner for Wet Pickup, for 55 Gallon Drum

Use to empty or fill sumps and other liquid reservoirs—this continuous-duty vacuum cleaner pumps in and out (turn the knob to switch from pumping into pumping out). Unlike other drum-top vacuums, it works only with closed-head drums that have two openings (not included). This vacuum cleaner removes coolant, sludge, slurries, and metal chips.
