Hydro-Vac systems filter mineral oils, soluble or synthetic coolants and other fluids at flow rates from 100 gpm to 10,000 gpm. Self-contained units can be installed above or below floor or in mobile configuration to handle single machines, machine centers, departments or entire plants. Add optional, trenching or sump pump systems and automatic chip processing for complete system efficiency.

Hydro-Vac vacuum filtration systems boost metal cutting productivity. Tool life doubles, triples or more. Cooling and lubricating fluids can last indefinitely. Uptime climbs because of fewer tool changes and less machine maintenance. Chip disposal is simplified. Critical tolerances and surface finishes improve dramatically.

Dual filtration for continuous operation.

Hydro-Vac systems use a unique dual technique to filter and recirculate process liquids. As dirty liquid enters the filter, floating debris and tramp oil is flushed to the discharge ramp and automatically skimmed off the surface by the filter conveyor flights.

Simultaneously, liquid is drawn through the filter medium at the bottom of the dirty reservoir by a filter/distribution pump which develops a vacuum of 15 inches mercury (7.4 psi differential). From the clean liquid vacuum chamber, the fluid is continuously pumped to the machines.

Automatic operation is ensured by a preprogrammed filter cycle. Initiated automatically when a preselected vacuum is reached, vacuum is eliminated by backflow of clean liquid into the vacuum chamber.

The flight conveyor and disposable filter media move a predetermined distance, usually a few inches. When permanent filter media is used, the backflow of clean liquid lifts retained solids from openings in the permanent media to prevent migration during indexing. During the short micro-index cycle, clean liquid is drawn from a reserve tank to ensure a continuous supply to machines.

Hydro-Vac systems build up a concentrated solids cake which enhances filtration. The micro-indexing feature permits retention of a concentrated solids cake on 90% of the filter area at all times. The filter's ability to develop greater vacuum differential as the solids cake increases maintains uniform flow through the media.

Media options filter fines to 1 micron.

Disposable filter media are designed for specific applications ranging from rough machining to grinding, honing and polishing. Larger fines can also be retained by permanent filter media belts manufactured from woven monofiliment fabrics. Permanent-type media that reduce operating costs associated with purchase and disposal of disposable media. Particulates down to a 1 micron level are removed by low cost, disposable, non-woven media.

High reliability. Low cost operation.

Hydro-Vac systems have only three moving parts: the filter/distribution pump, the flight conveyor and the vacuum break valve. This keeps maintenance low and system reliability high.

Your energy costs are low because the same pump generates filter vacuum and delivers a pressurized supply of liquid to production machines. Pumps incorporate a patented auto-priming feature that eliminates the need for self-priming pumps.

Worldwide service and engineered applications.

Hydro-Vac is the "original" vacuum system for filtering metalworking liquids. More than 6,000 systems are installed worldwide. Hydromation stands behind every system with a worldwide sales and service network that solves problems and stocks spare parts and filter media.
