OIL AND SWARF
Recover 95 % cutting fluid, segregate scrap chips, restart production in under ten minutes.
Depureco flow-inversion sump vacuums pump out coolant at up to 120 GPM (2 gal s⁻¹), strain chips through a reusable 150 µm stainless basket, then push filtered fluid straight back into the machine—all without lifting a pail. Reduce coolant spend, stop slip hazards, and keep your CNCs cutting.
Perfect for prototype labs, job-shops and single-spindle CNCs
Need to empty a Haas Mini-Mill or tabletop machining centre without killing spindle time? Our up-to-30-gallon sump vacuums use the same flow-inversion technology as our larger units, pulling chips and coolant through a 150-micron stainless basket and pumping 95 % clean fluid back to the tank in minutes. At just 20 in × 24 in, they fit between machines, run on a single 120 V outlet, and deliver 1 gallon-per-second recovery—more than four times the airflow of a consumer wet-dry vac.
Keywords: 30-gallon sump vacuum, small-CNC coolant recovery, compact industrial sump cleaner.
The sweet spot for mid-size VMCs, horizontal lathes and dual-pallet machining cells.
If your machines hold 40–75 gal (150–280 L) of emulsion, manual scoop-out means 30–45 minutes of dead time. Our 75-gallon coolant-recovery vacuums move 1–1.5 gallons per second, separate ferrous and non-ferrous chips for premium scrap value, and feature an auto float-switch that stops suction before overflow. Twin side-channel blowers deliver 24/7 duty at just 72 dB, while the clear sight-tube shows remaining capacity at a glance.
High-capacity flow-inversion for large HMCs, gantry mills and central coolant pits.
Large-body CNCs and multi-machine coolant pits demand serious throughput. Our high-capacity 300-gallon sump vacuums (RAM 500 T & RAM 1000) deliver up to 2 gallons per second—emptying, filtering and refilling a 1000-L sump in under ten minutes. A 70 mm antistatic hose prevents bird-nesting on long stringers, and reverse-flow discharge means no secondary pump to clog. Fork-pocket frames let one forklift relocate the unit, and optional endless-bag cyclonic separators boost chip storage to 580 L.
Keywords: 300-gallon sump vacuum, high-capacity coolant recovery, flow-inversion sump cleaner, heavy-duty CNC maintenance, 2 gallon-per-second chip vacuum.
A stainless-mesh chip basket teamed with a 150-micron PPL filter keeps metal shavings out of the fluid stream. Chips drop dry into the basket for premium scrap resale, while the filtered coolant drains into an epoxy-coated steel tank ready for immediate reuse or drum transfer.
Result: Clean coolant back in the machine, zero pump damage, zero filter consumables.
Every gallon of coolant you reclaim is a gallon you don’t buy—or pay to haul away. By removing solids, a Depureco sump vacuum cuts coolant disposal fees, eliminates tramp-oil fines from waste haulers and converts dry chips into high-value scrap metal. Shops typically save $9,500+ per CNC per year in fluid, labour and scrap uplift.
A heavy-duty submersible discharge pump lets you vacuum and refill at the same time: suction pulls chips and dirty coolant into the tank while the pump returns filtered fluid to the machine at up to 120 GPM (2 gal s⁻¹). Continuous operation means no waiting for the tank to fill, no secondary transfer step, and no downtime between shifts.
Grounded hoses, IP55 motors and optional ATEX Zone 22 certification eliminate ignition sources; float-switch prevents messy over-fills—meets OSHA 1910.22 and NFPA 652/484 housekeeping rules.
Reverse-pulse blast clears the 150 µm basket in <10 s—no tool, no downtime, constant airflow.
Side-channel blowers run below conversational level—ideal for lights-out machining cells and night shifts.
500 × 600 mm chassis fits between CNC rows; heavy-duty casters glide over chip piles; fork-pocket frame on RAM series for one-forklift relocation.
Hinged lid and quick-release basket let operators rinse filters in under two minutes—no loose fasteners to drop in the tank.
Side-channel electric blowers draw 30 % less energy per CFM than comparable Venturi air vacs—lower utility cost, smaller compressor.
Snap-on cyclones, endless-bag drums, and tilting 580 L bins protect filters and multiply chip capacity for high-volume production.
