CLEAN TANKS FASTER. RECOVER COOLANT. KEEP MACHINES RUNNING.
Sump Vacuums for CNC Tank Cleaning
CNC sumps collect everything that slows maintenance down: coolant, tramp oil, metal chips, swarf, sludge, fines, and the mystery layer sitting at the bottom of the tank.
Depureco sump vacuums help machine shops clean tanks faster by vacuuming mixed liquid and solids, separating chips from coolant, filtering the fluid, and pumping it back into the machine or into a drum.
Collect Faster. Filter Coolant.
Vacuum chips, filter coolant, and pump it back fast.
Water-Based Coolant, Metal Chips & Swarf
Water-based coolant sump vacuums are used for CNC tanks containing coolant, cutting fluid, aluminum chips, steel chips, swarf, shavings, fines, and light sludge. These coolant recovery vacuums help machine shops separate metal chips from liquid, filter coolant, recover reusable fluid, and pump clean coolant back into the CNC machine or into a drum.
Heavy Metal Sludge, Straight Oil & Swarf
Heavy-duty oil and swarf sump vacuums are used for CNC tanks with straight oil, thick coolant, tramp oil, metallic sludge, grinding sludge, dense swarf, heavy chips, and settled fines. These industrial sump vacuums support oil recovery, sludge removal, swarf separation, coolant tank cleanout, chip basket collection, and reduced maintenance downtime in metalworking and machining facilities.

Built-In Motor Shield — No Mist, No Burn-Out.
Oil-mist protection is important in CNC sump vacuum applications because coolant droplets, oil mist, and vapor can affect motor performance over time. Depureco sump vacuums use oil-resistant motor protection to support coolant recovery, oil and swarf cleanup, cleaner exhaust handling, reduced mist exposure, and longer-lasting performance in machine shop maintenance environments.

CNC Sump Vacuum FAQs
Practical answers for coolant recovery, chip separation, sludge removal, and pump-back cleaning.
How do I know which sump vacuum is right for my CNC tank?
The right sump vacuum depends on what is actually in the tank: coolant type, total liquid volume, chip load, sludge level, swarf density, discharge distance, available power, and how often the sump is cleaned.
For lighter water-based coolant and routine chip recovery, a compact or mid-size coolant sump vacuum may be enough. For straight oil, dense sludge, heavy swarf, long hose runs, or large-volume tanks, a higher-capacity or heavy-duty RAM sump vacuum is usually a better fit.
This FAQ supports sump vacuum selection, CNC sump vacuum sizing, coolant sump vacuum, CNC coolant vacuum, coolant recovery vacuum, oil and swarf vacuum, heavy sludge sump vacuum, RAM sump vacuum selection, tank size, chip load, sludge level, discharge distance, available power, and CNC machine shop maintenance search intent.
Can a sump vacuum handle coolant, chips, swarf, and sludge at the same time?
Yes — that is the point of a CNC sump vacuum. A sump vacuum is built to recover mixed liquid and solids from the same tank, including coolant, cutting oil, metal chips, swarf, fines, and sludge.
The vacuum pulls the material into the tank, separates solids with a basket or internal collection system, and allows the recovered liquid to be discharged, transferred, or pumped back depending on the model and fluid condition.
This FAQ supports CNC coolant vacuum, sump vacuum for coolant and chips, metal chip vacuum, chip vacuum, swarf vacuum, oil and swarf vacuum, coolant recovery vacuum, sludge vacuum, mixed liquid and solids recovery, metal chip separation, and CNC tank cleaning search intent.
Can I pump coolant back into the CNC machine after vacuuming it out?
Yes, if the coolant is still usable and the sump vacuum is configured for pump-back or discharge. Many Depureco sump vacuums are designed to recover coolant, separate chips and swarf, and move filtered liquid back into the CNC tank or into a drum.
The vacuum removes solids from the liquid, but your team should still check coolant concentration, tramp oil, odor, bacteria, and overall fluid condition before returning it to production.
This FAQ supports pump-back sump vacuum, coolant pump-back, filtered coolant reuse, recover coolant from CNC sump, coolant recovery vacuum, coolant reclaim vacuum, coolant filtration, coolant concentration, tramp oil, bacteria, CNC tank cleaning, and machine tool maintenance search intent.
What is the difference between a sump vacuum, a wet vacuum, and a transfer pump?
A transfer pump is mainly for moving liquid. A general wet vacuum is mainly for basic wet pickup. A CNC sump vacuum is built for the full tank mix: coolant, oil, metal chips, swarf, sludge, and fines.
The biggest difference is separation and recovery. A sump vacuum can collect liquid and solids together, separate chips and swarf from the recovered fluid, and support discharge or pump-back. That makes it a better fit for machine tool sump cleaning than a wet vac or pump alone.
This FAQ supports sump vacuum vs wet vacuum, coolant recovery vacuum vs general wet vacuum, sump vacuum vs transfer pump, wet dry vacuum vs liquid recovery vacuum, best vacuum for oil coolant and sludge, CNC sump cleaning system, mixed media vacuum, chip basket separation, and coolant recovery search intent.
When should I choose a heavy sludge or straight-oil sump vacuum?
Choose a heavy-duty oil and swarf sump vacuum when the tank has straight oil, thick coolant, dense swarf, grinding sludge, metallic fines, or settled material that packs into corners and chip conveyor areas.
These applications usually need more than basic liquid recovery. Look for stronger suction, enough liquid capacity, a practical solids collection setup, and discharge options that match how your shop handles oil, sludge, and recovered fluid.
This FAQ supports heavy sludge sump vacuum, straight oil sump vacuum, oil sludge vacuum, industrial sludge vacuum, oil and swarf vacuum, swarf vacuum cleaner, CNC tank sludge removal, grinding sludge vacuum, metallic fines, dense swarf, and heavy-duty sump vacuum search intent.
What sump vacuum specs matter most for CNC tank cleaning?
The most important specs are liquid capacity, solids capacity, discharge type, suction performance, hose size, and available power. For most CNC sump cleaning jobs, capacity and discharge setup matter just as much as raw suction numbers.
If your tank has a lot of liquid, focus on recovery capacity and pump-out speed. If your tank has heavy chips or sludge, focus on solids handling, basket design, nozzle selection, and vacuum performance. If your machine is hard to reach, hose length and vacuum strength become more important.
This FAQ supports sump vacuum specs, CNC sump vacuum capacity, coolant recovery vacuum capacity, liquid capacity, solids capacity, discharge type, pump-out speed, suction performance, hose length, chip basket, swarf separation, sludge removal, and machine shop sump cleaning search intent.
Will a sump vacuum reduce CNC machine downtime?
A properly matched sump vacuum can reduce downtime by making tank cleanout faster, cleaner, and easier to repeat. Instead of manually scooping chips, sludge, and coolant, the vacuum recovers the tank contents, separates solids, and helps move usable coolant back into the machine or into a drum.
The time savings depend on tank size, coolant volume, sludge load, chip volume, access points, and the vacuum model. The biggest gains usually come from shops that clean sumps manually or use separate pumps, buckets, and cleanup tools.
This FAQ supports reduce CNC downtime, sump vacuum ROI, manual sump cleanout alternative, coolant recovery savings, machine shop maintenance efficiency, reduce manual cleaning, recover coolant faster, chip separation, sludge removal, and keep machines cutting search intent.
What should I tell Depureco to get the right sump vacuum recommendation?
Tell us the machine type, tank size, coolant or oil type, estimated gallons, chip material, sludge level, discharge location, available power, hose distance, and how often the sump is cleaned.
Photos or short videos of the tank help too. If we can see the chip load, sludge buildup, access points, and discharge area, we can recommend the right sump vacuum, kit, nozzle, and pump-back setup faster.
