WORKING OF OIL SKIMMER This is a Belt Type Oil Skimmer. When power is switched on, the belt moves over Head Pulley (mounted on Motor Shaft) lifting the emulsion of coolant & oil from sump. The Tail Pulley supported by a chain keeps the belt straight. Skimmers are specified based on Belt Reach (R) which is measured from the Mounting Base to the bottom of the Tail Pulley. A Scraper removes the mixture from the moving belt and deposits it to the Collecter Chamber where oil gets separated from coolant by means of gravity (The oil floats over the coolant). The oil is then discharged to a disposal container and the coolant is discharged back to the coolant tank. This returns upto 90% of the coolant in the skimmed liquid emulsion and sends only waste oil in trash, saving tremendous cost due to almost full coolant recovery.

INSTALLATION & OPERATION 1. Hold Oil Skimmer Unit upright & mount the belt over Head Pulley connected to the motor. 2. Keep the belt straight & support it over Tail Pullley. 3. Place the Mounting Magnet underneath of Oil Skimmer onto the steel base of coolant tank / CNC machine, lowering the belt into the fluid as deep as possible. Ensure that the belt can move freely without touching any part of the tank / machine. NOTE Oil Skimmer with 30 mm Belt Width can fe fitted through a 2” dia. bung hole on a 55 gal (205 litre) drum. 4. Connect the outlet port to a discharge hose leading to a disposal container. 5. Connect the skimmer to power supply using AC adapter & switch ON power. 6. After a few minutes of operation, the skimmer will start discharging coolant back to the tank & the waste oil into disposal container.

WARNINGS & INSTRUCTIONS • • • • • •
Never use oil skimmer in explosive environments Do not disassemble when power is on Oil Skimmer requires floating fluid to be in a liquid, free-flowing state Ensure the tank / sump provides sufficient volume of fluid to allow adequate time for oil / coolant separation Excess of metal chips in sump may obstruct the free movement of skimmer belt. Ensure the sump gets cleaned at regular intervals If tank / sump has an irregular shape, put the oil skimmer where the largest amount of oil accumulates
