Local filter designer and manufacturing company Filter Focus's Seal Saver cylinder cover, launched last month, helps extend hydraulic seal and cylinder life at least threefold and protects seals and cylinders from the dirt and debris in the harsh African environment, says Filter Focus.
They tell Engineering News that the Seal Saver is a breakthrough in preventive maintenance tools, which helps prevent cylinder rod scoring, lessens dings and dents caused by falling debris and prevents pitting corrosion, owing to exposure to chemicals.
Further, the product reduces the risk of oil leaks and particle contamination of the hydraulic system, which reduces downtime and lowers repair costs, they explian.
"The product prevents silt-sized particles from entering the hydraulic system through the rod seals. If these tiny particles get into the system, they can act as a lapping or grinding compound, causing wear to valves and pumps. Eventually, this will damage the hydraulic system," they say.
The Seal Saver is heat, oil, chemical and water resistant and overcomes a veriety of hydraulic and air-cylinder rod maintenance challenges. The unit has been incorporated as a preventive maintenance tool in several industries, including oil and gas, construction, mining, waste management and quarrying, as well as at wood product manufacturers, refineries and marinas.
It is manufactred by US-based hydraulic systems filtration and preventive maintenance company Fluid Control Services and has been on the US market since 1998. The cover incorporates a wraparound design and Velcro closure system that allows the unit to be installed without having to disassemble the cylinder, Filter Focus points out.
"Once the Seal Saver is installed, it opens and closes like an accordion as the cylinder moves," they note.
The Seal Saver can be reused after the hydraulic cylinder has been replaced, Filter Focus, adding that it lasts for more than 25 years.
