The heavy-duty hydraulic systems in today’s industrial plants endure some of the toughest operating conditions. They run under extreme pressures, at increasing speeds and are working harder than ever before. Now, in light of the trend toward smaller reservoirs, even more stress is being put on this equipment.
These factors can present many challenges—one of the most important of which is sludge buildup. With the smaller systems now in operation, air and heat are not able to escape as easily as they are with larger reservoirs. Water may not separate as effectively. Contaminants may accumulate faster. As the rate of oxidation rises, so does the risk of harmful sludge buildup. Even with a good filtering system, excessive sludge can plug filters, which increases equipment wear and can seriously damage the hydraulic pump.
