Eriez Debuts Rotor Bowl Filter

The Eriez Hydroflow  line of centrifuge filter systems feature an open rotor bowl fitted with a long-life, removable flexible liner.  These systems are often combined with high capacity cartridge filters to polish dirty fluid and remove fines down to five microns.

The Eriez Hydroflow centrifuge product line offers many combinations of centrifuge models, tank sizes and pump pressures used with  the high performance model HP-20 single bowl or model HP-40 double bowl.

These centrifuge filter systems are applicable for tool and cutter grinding, glass and ceramic grinding, filtering honing and micro finishing oil, vibratory finishing, wire drawing and all types of carbide grinding. Besides removing fines down to five microns, these filter systems offer quick and easy sludge recovery, re-usable sludge collection liners, low operating cost and come in a compact size with low inlet height.

Eriez Hydroflow centrifuge filter systems operate on a basic principle: An open rotor bowl is driven at high speed. Into this is fitted a long-life removable flexible rotor liner shaped to the inner contour of the rotor. The rotor liner is secured by a removable vane assembly.

Dirty coolant enters at the top of the rotor assembly and is deflected by the center cone toward the base of the bowl. Centrifugal force acts on the dirty coolant, packing the foreign matter into a “cake” against the wall of the rotor liner. The cleaned coolant or oil overflows into the clean tank and is returned to the machine tool by a separate pump.
 
Environmentally-friendly re-usable liners offer clean, fast disposal or recovery of the sludge cake extracted from the coolant. Cleaning takes only a few minutes and its frequency depends largely on the stock removal rate. These liners have 250in³ (6350mm) of solids capacity or will collect approximately 20/50 lbs sludge cake.

These highly efficient centrifuge systems have no consumable cost, no disposal of spent media and no stocking of medial roll. They also employ a safety feature, including a gas shock on the cover and a timer operated lid lock to prevent opening during operation.
