Oilybits RPC-103 'Raw Power Extreme' Spinning Bowl Centrifuge

PLEASE NOTE - This is a self-assembly kit in component form, the kits are of USA manufacture, and so threads and fixings are imperial, you will need a comprehensive tool kit and basic skills to assemble it, and wire it up safely. Oilybits now include a pack containing some items which will enable completion without having to purchase extra electrical components, the responsibility of safe assembly is that of the purchaser.

The Raw Power Centrifuge is an american designed & manufactured, high quaity, high precision, high speed, spinning-bowl centrifuge, for general centrifugal separation of liquids which are not agressive to the machines component materials.

Unlike Oilybits OB Series Centrifuge, the Raw Power Centrifuge does not use any of the incoming oil for essential lubrication, and therefore everything that passes through the centrifuge had been 'cleaned' to some extent, the slower the centrifuge is fed, the greater the extent of cleaning.

The Raw Power Centrifuge does not use filters, no waste media is created in using the machine, it also does not utilize a pump, and therefore the oil that goes in can be contaminated to a greater extent than oil which needs to pass through a pump. Particle size is limited to approximately 5mm Dia., this is the clearance between the rotor and the performance optimiser through which the dirty oil first flows, without the Performance Optimiser in place, the particle size increases to approximately 15mm Dia., the bore of the inlet hose tail.

The Raw Power Centrifuge is supplied as standard with a 'Performance Optimizer', this increases the efficiency of the centrifuge for ultimate cleaning performance while maintaining the easy and quick cleaning ability of the open bowl design. The optimizer bolts in to the rotor bowl with no modification and does not need to be removed when cleaning the bowl. The optimizer gets the oil spinning at full RPM prior to entering the bowl, rather than hitting the bowl static, this reduces turbulence / imbalance in the bowl. Also, the Performance Optimiser feeds the incoming/dirty oil directly to the outside wall at the bottom of the bowl, forcing the dirty oil to have to work its way from bottom to top, and outside to inside, then over the lip and out of the bowl, maximising its residence time, and therefore the efficiency of the cleaning operation.

The Raw Power Centrifuge has a dedicated drainage port for dirty oil and any liquid sludge, when the bowl stops spinning, the contents flood the base of the bowl and drain out through 3 small ports, into a sump beneath the bowl, and then out through a dedicated fitting below the bowl. Large particles over approximately 4mm will need manually scraping out of the bowl as they are too large to pass through the 3 small drainage ports.

These centrifuges are also popular for recovering precious metals in jewellery manufacture, offcuts, swarf, chips, and pastes from polishing can all be recovered or seprated from oils and coolants in a centrifuge, without any valuable metal being trapped in a filter element and lost.
