HYDRAULIC FILTRATION

Hydraulic Oil Contaminants

Injection molding, heavy machinery, bending machines, lifts, elevator equipment, construction equipment, cutting machines, plate rollers, straddle carriers, stamping presses, mining and quarry equipment can have serious problems associated with water and/or particulate contamination. Water contamination in hydraulic oil produces an emulsion, which accelerates corrosion and causes metal deterioration. Similarly, particulate contamination can accelerate wear on vital parts, i.e. pumps, bearings, gears, valves, seals, etc. The presence of water and/or particulate contamination in hydraulic oil will increase downtimes, labor costs and disposal costs. 

Solution: Filter Works Filtration Systems

Water and particulate contamination does not mean that the hydraulic oil must be disposed of and replaced. Through multi-pass filtration, the water and/or particulate can be removed from the hydraulic oil and thus extend the fluid life. Additionally, both fine and gross contamination can be removed through the use of multi-pass filtration. Gross contamination (100 micron and larger particles) is usually removed with a bag filter(s) and fine contamination (down to one micron) is removed with our depth filter(s). 

Multi-pass filtration is performed on a kidney loop basis. In a kidney loop, the sump/reservoir hydraulic oil is filtered continuously, independent of the machines normal operation. Since filtration occurs independent of the machines normal operation, a specified or minimum flow rate does not have to be maintained. Filtration can be performed slowly and continuously reducing total contamination in the sump/reservoir to one micron or less.
