There are a few ways to get the liquid out of a drum:
You can use a pump. Some pumps are even made to mount straight onto the lid of the drum.
You can siphon the liquid out, if you can get the drum higher than where you want to put the liquid. And if you have the time.
You can turn the drum over. I used to do field service in chemical plants…some of them had drum handlers on fork trucks that could pick up and tilt the drum to pour the liquid out. Some of them pushed the drum over and simply let the liquid spill into a pit or below-grade sump.
But pumps break down. Siphoning is finicky and slow. I’m loath to knock the skills of the fork truck operator that can pour out a drum like a sommelier pours a fine wine. And I’ll never forget the first time I saw an operator half-roll/half-dance a drum to the edge of that pit and let the liquid dump as he dropped it precisely where he wanted it…however, even in the context of the inner recesses of a chemical plant, it was simple, but inelegant.
EXAIR has an engineered solution that preserves the simplicity, though: the Reversible Drum Vac. Thread the standpipe into the bung connection and the RDV itself into the vent, and that drum is now a two-way pumping system, able to be emptied via a 10 foot long Vacuum Hose in as little as a minute and a half. Turn the knob on the RDV to switch modes, and you can fill that same drum just as fast.
The EXAIR Reversible Drum Vac Systems come with a variety of configurations and options:
Made to fit an existing 30, 55, or 110 closed top steel drum in good condition.
Mini Reversible Drum Vac System comes with a 5 gallon drum.
Deluxe Systems add a Drum Dolly and a set of tools.
Premium Systems add a drum (30, 55, or 110 gallon,) an upgrade to Heavy Duty Aluminum Tools, and a 20ft compressed air supply hose with shutoff valve and pressure gauge.
High Lift Reversible Drum Vacs generate a suction head of 180″H2O for maximum lift. They’re also specified for higher viscosity liquids.
Below is a great video that showcases just how easy it is to from installing the Reversible Drum Vac to using the Reversible Drum Vac and just how fast the RDV operates.
There are some very good reasons to consider an EXAIR compressed air operated Industrial Housekeeping Product for liquid applications:
*Durability. No moving parts means nothing to wear or get damaged.
*Safety. No electricity means no dragging an energized cord through a wet area.
*Convenience. All you need is a supply of compressed air.
*Reliability. If you supply it with clean, dry air, it’ll run darn near indefinitely, maintenance free.
Depending on the needs of the application, we have different models to choose from:
Reversible Drum Vacs
If you’ve got a closed top steel drum that’s in good condition, look no further than the Reversible Drum Vac System. It comes with everything you need to turn that drum into a powerful, 2-way liquid pumping system. This is great if you just need to park the drum in one spot and suction out a sump or tank on a regular basis, using its 10 foot Vacuum Hose & Suction Wand. They’re in stock for your existing 30, 55, and 110 gallon drums. A 5 Gallon Mini Reversible Drum Vac System is also available; it includes the drum as well.
If you’d like a little mobility, and a way to clean up floor spills, then the Deluxe Reversible Drum Vac System might be what you’re looking for. It adds a Drum Dolly and our Spill Recovery Kit…it consists of a floor-length wand and a dual squeegee tool. It also comes with a set of plastic tools (crevice tool, small skimmer, and two 20″ extensions) and a Tool Holder with clips for the tools, and magnets to attach to the drum. We keep them in stock for your existing 30 and 55 gallon drums. It also comes in the 5 Gallon Deluxe Mini Reversible Drum Vac System(drum included.)
For a complete system, the Premium Reversible Drum Vac Systems have everything you need for most any liquid drum transfer job: they add a drum, lid & latch ring, as well as a compressed air supply hose & shutoff valve, and an upgrade to Heavy Duty Aluminum Tools. They’re available with 30, 55, or 110 gallon drums; in stock.
Any of the 30, 55, or 110 Gallon systems are also available with our High Lift Reversible Drum Vac. These provide for increased performance with more viscous liquids, and/or when the liquid needs to pumped from a depth of up to 15 feet. They are outfitted identically to the standard Reversible Drum Vac Systems, except they come with a 20 foot Vacuum Hose.
As versatile as the Reversible Drum Vacs are, we also incorporate them into another 2-way pumping system, designed to help you get maximum life and performance from machine tool coolant and cutting oils: The award-winning Chip Trapper Systems.
Powered by the Reversible Drum Vac, the Chip Trapper System draws the incoming liquid into the drum through a Filter Bag, which retains (or “traps”) any particulate as the drum fills with liquid. Then, the freshly filtered liquid can be immediately pumped back out, while the particulate remains in the bag. Once the bag is full, simply remove the drum lid, unhook the bag, empty it out, and return it to service. The Chip Trapper System comes with two Filter Bags, in fact, so you can clean one while you use the other. They are available, from stock, in 30, 55, and 110 gallon sizes. They are all three available in High Lift configuration as well, with a 20 foot Vacuum Hose.
One of the great things about being an EXAIR Application Engineer is the variety of applications that find their way through our proverbial doors. In a given day we could be anything from solve static problems for a garment manufacturer to prevent an overheating condition at a pumping station.
The latter of the applications mentioned above has played out over the last few days with an end user of our products in Kuwait. This end user operates a sewage pumping station which uses 10 dry well pumps located 30m (99 ft.) below ground. The rooms which house the pumps are not cooled, and as a result, the bearings within the pumps tend to overheat and take considerable time to cool.
What this application needed was an efficient and effective way to cool these motors (and their bearings) from a measured high of 90°C (194°F) to ambient temperatures. And, when it comes to a convective heat transfer such as that found when cooling by passing an airflow over a material, the greater the volume of air, the greater the cooling.
Enter the Super Air Amplifier. An air amplifier will multiply the volume of air fed through the unit. For example, if we supply a 4” Super Air Amplifier with 80 PSIG line pressure, it will consume 29.2 SCFM and move a volume of 730 SCFM at the outlet of the unit. At a distance of 6” away, the air volume will further amplify to 2,190 SCFM.
What this means for this application, is that we can use a small amount of compressed air to generate HUGE air flows over these motors, bringing down their temperatures and preventing the overheating condition.
If you have a similar application or are in need of a potential EXAIR solution, contact an EXAIR Application Engineer.
Last week I wrote a blog about cooling sewage pumps at a facility in Kuwait. The pumps in question were overheating and needed a way to cool the pump motors down to ambient temperatures. And, fortunately, our Super Air Amplifiers proved to be a great fit.
On the other side of the same facility, there were control panels for 3.3kV pumps that were also experiencing an overheat condition. But, the motors were operating properly, it was the electrical panels that were tripping due to excessive heat.
The overheating of the electrical panels would shut down the pump motors, bringing operations to a screeching halt. What the end user needed was a way to regulate temperature within the electrical panels that was small, effective, and easy to use.
This application, and its requirements, were a perfect fit for our Cabinet Coolers. Cabinet Coolers are small, effective, easy to install, require no maintenance, and are incredibly easy to use – once installed and setup, they regulate themselves.
By receiving a completed Cabinet Cooler Sizing Guide, EXAIR engineers are able to calculate heat load for an enclosure and recommend a suitable solution.
If you have an overheating cabinet or electrical panel, call an EXAIR Application Engineer.
