A floating-weir quotation is incomplete when it gives only a litres-per-minute figure. You need the weir dimensions, level range, liquid conditions, pump arrangement, electrical details, materials, package boundaries, and acceptance criteria before you can compare suppliers or confirm that the skimmer will fit your tank.
Key takeaways
- Request weir width, immersion range, oil capacity, water recovery, and minimum oil-layer thickness.
- Confirm tank depth, liquid-level variation, turbulence limits, and maximum operating depth.
- Compare pump, piping, controls, materials, options, exclusions, and installation responsibilities.
- Define commissioning tests and written acceptance limits before selecting a Pune supplier.
The floating weir specifications your quotation must show
Your quotation must show the weir width and overall dimensions, skimming width, adjustable immersion or operating-level range, minimum liquid depth, oil-removal capacity, water recovery or water percentage, minimum recoverable oil-layer thickness, maximum operating depth, and acceptable surface-flow or turbulence limits.
Require these conditions beside every capacity figure:
- Oil viscosity, density, temperature, layer thickness, solids content, pump arrangement, hose length, lift, and oil-to-water recovery ratio.
- The defined weir adjustment method: lowering the lip increases water intake; raising it can lose oil when the layer thins or the liquid level changes.
- ASTM F2709 test reference, plus the test medium and conditions behind the stated recovery rate and effectiveness.
| Oil recovery rate | Water recovery rate | Maximum viscosity | Maximum solids size | Performance at buyer’s temperature |
|---|---|---|---|---|
| Actual value and units | Litres per minute or percentage | mPa·s or cP | Millimetres | Measured result at stated temperature |
Do not compare a thin, warm oil layer tested with a short discharge line against a viscous mixture tested at greater head. Those figures describe different duties, not competing machines.
For floating weir oil skimmer specifications in Pune, ask the supplier to complete this table using your oil, temperature, tank level, hose length, lift, and surface-flow condition. A blank “capacity” column hides the water pickup and pump duty that determine whether the skimmer will work.
Tank dimensions, liquid levels, and how the floating weir operates
Tank geometry determines whether a floating weir will fit and skim effectively; nominal capacity does not. For a component-washing machine or machining-fluid tank, check the actual tank against the skimmer, including guide rails, anchor points, float travel, lifting access, and maintenance clearance.
Floats support the skimmer at the surface while the weir lip rises and falls with changing liquid level. The surface oil layer flows over the adjustable lip into the throat, then through a suction connection to the transfer pump, hose or pipe, and collection tank.
Set immersion correctly: too deep increases water pickup; too shallow loses oil when the layer thins.
Provide these site details:
- Tank or pit length, width, minimum and maximum liquid depth, usable freeboard, access-opening size, liquid-level variation, and maintenance clearance
- Surface velocity, inlet and outlet locations, turbulence, sludge, chips, tramp solids, coagulated coolant, emulsified oil, and required minimum oil-layer thickness
- Guide-rail and anchor locations, float travel, lifting route, suction-connection position, collection-point location, and the defined weir-adjustment method
A calm, sufficiently deep surface gives the best result. Rapid level changes, shallow tanks, heavy floating solids, and strong turbulence increase water pickup or block the throat.
Specify a pump or PLC interlock to stop transfer when the washer is empty, the collection tank is full, or the liquid falls below the safe operating range. This detail matters when comparing an oil skimmers manufacturer for floating weir specifications in pune.
Pump, piping, controls, and construction details to compare
A floating weir collects the surface layer; the separate transfer pump largely determines discharge rate, water entrainment, viscosity handling, hose length, and lift. Compare the pump and piping, not just the skimmer head.
| Item | Require in quotation | Why it decides usability |
|---|---|---|
| Pump | Type, flow at stated head, maximum viscosity and solids size, suction lift, dry-run limit | Confirms performance with the oil-water mixture |
| Suction and discharge | Strainer opening, clean-out access, isolation valves, flexible connectors, bypass, hose length and lift | Prevents blockage and excessive restriction |
| Construction | Wetted parts, frame, floats, seals, elastomers, corrosion-resistant finish | Must suit oil, coolant, detergent, temperature and solids |
List the electrical data explicitly:
- Supply voltage, phase, frequency, motor rating, enclosure or IP rating, starter or VFD, overload protection, emergency stop, cable length, earthing and panel location.
- 415 V, three-phase, 50 Hz is common in Indian plants; verify the actual site supply before ordering.
- State the pump interlock for low liquid level and collection-tank high level. Include safe restart logic.
Require material compatibility in writing. A seal that swells in detergent or a float that corrodes in coolant can stop recovery even when the motor is correctly sized.
For hazardous service, provide the area classification and certification basis for the motor, instruments, panel and earthing. “Industrial” does not prove explosion protection; name the applicable certified construction or acceptance basis.
Floating weir skimmer package details: inclusions, options, and exclusions
A complete floating weir skimmer package details schedule separates standard inclusions, optional accessories, and site-provided items. A floating weir oil skimmer supplier in Pune should price each line separately:
- Floating weir assembly, buoyancy floats, frame or guide arrangement, suction/discharge hose, recovery pump, suction strainer, isolation valves, flexible connectors, guards, and fasteners.
- Control panel, oil collection vessel, oil-water separation outlet, level controls, high-level switch, low-level pump protection, interlock wiring, and spare seals: mark each as included or excluded.
Optional accessories - Larger collection tank, additional hose, chip basket, automatic level control, VFD, lifting frame, standby pump, downstream separator, and hazardous-area-rated electrical equipment.
Site-provided items - Tank or pit, civil supports, anchor bolts, lifting equipment, electrical cabling, isolator, compressed air where required, drainage, downstream oil storage, and tank modifications.
| Quotation line | Buyer must confirm |
|---|---|
| Installation drawings | General arrangement and foundation loads |
| Documentation | Operating/maintenance manuals and recommended consumables |
| Service | Commissioning and operator training |
| Commercial limits | Warranty boundaries and spare-parts schedule |
Cleanosk Automation can be considered during a Pune supplier review, but accept no inclusion without a written datasheet or quotation line. A supplier quoting only the skimmer head has not quoted a complete package; the pump, hose, controls, installation responsibilities, and downstream collection arrangement remain undefined.

How to specify commissioning and acceptance before choosing a Pune supplier
Approve the supplier only after a witnessed acceptance test using your oil, coolant, or wash liquid—not clean water alone. Record these conditions on the test sheet:
| Test condition | Record before running | Result to accept |
|---|---|---|
| Liquid and oil | Type, viscosity, density, temperature, layer thickness, solids load | Matches purchase-order values |
| Tank and flow | Liquid level, surface flow, pump head, hose length, operating time | Same conditions for every supplier |
| Performance | Oil recovery rate, water recovery rate or water percentage | Meets the guaranteed figures |
| Operating limits | Minimum stable oil-layer thickness and maximum operating depth | Demonstrated without unstable pickup |
| Fault behaviour | Overflow, blockage, dry running, strainer access | No unsafe or unreported failure |
During commissioning, watch the weir track level changes without scraping the tank. Confirm that the pump cannot run dry, the strainer can be isolated and cleaned safely, and the emergency stop stops the pump.
Require live demonstrations of the low-level and high-level interlocks, collection-tank level control, restart procedure, and chip or sludge clean-out. Record the settings and attach photographs to the signed commissioning checklist.
For a Pune installation, confirm the actual supply voltage, phase, frequency, access route, installation date, lifting method, operator training, and responsibility for civil work and cable work. Compare quotations under identical test conditions, with a signed inclusion-exclusion schedule.
Attach the approved general arrangement drawing, specification table, performance guarantee, commissioning checklist, manuals, warranty limits, and recommended spare-parts list to the purchase order.
