Product description
The Oil Skimmers Model 7V Brill® super-duty tube oil skimmer is designed for high-capacity removal of floating oils, fats, grease and oily waste from water and industrial process liquids. Using a large free-floating collector tube, the skimmer continuously removes tramp oil from the liquid surface while minimizing water carryover. The Model 7V is engineered for demanding industrial environments where high oil recovery capacity and rugged construction are required.Technical overview
Brill® tube oil skimmers operate using a continuous loop collector tube that floats freely across the liquid surface. Oil naturally adheres to the outside of the tube and is transported into the skimmer housing where scraper blades remove the oil and direct it into a collection container. Because the tube floats freely on the surface, the skimmer automatically follows fluctuating liquid levels and can move around floating debris while continuing to collect oil. The Model 7V includes a larger 1-inch collector tube and adjustable speed control, allowing the skimmer to be optimized for different oil types, oil thickness and operating conditions. :contentReference[oaicite:1]{index=1}Oil removal capacity
The oil removal capacity of a tube oil skimmer depends on several operating factors including oil viscosity, oil layer thickness, temperature and system configuration.
The Model 7V Brill® tube oil skimmer is designed for large tanks and heavy-duty applications and can remove:
- up to 200 gallons of oil per hour
- approximately up to 757 litres per hour
Actual oil recovery may vary depending on operating conditions, oil type and collector tube length.
Operating principle
The collector tube floats freely on the liquid surface and is slowly driven by the skimmer motor. Oil adheres to the outside of the tube while water is largely rejected. As the tube enters the skimmer housing, scraper blades remove the oil from the tube surface and direct it into the discharge outlet. The cleaned tube then returns to the tank surface where the skimming cycle continues.Material options
Typical construction materials include:- Heavy-duty cast housing
- Epoxy coated surfaces for corrosion resistance
- Ceramic wear components
- Ceramic drive wheel fingers
- Ceramic pressure blocks
- Industrial gear motor drive
- Collector tube available in standard or high temperature material
Available micron ratings
Oil skimmers do not operate based on filtration micron ratings. Instead, separation occurs because oil adheres naturally to the surface of the collector tube while water is rejected. This allows selective removal of floating oils, fats, grease and oily waste from the liquid surface.Design and construction
