EM18 VACUUM PUMPS - PRODUCT SERVICE RECOMMENDATIONS Performance optimisation through regular maintenance. As with all mechanical devices, regular maintenance can help ensure optimised, safe performance of your Edwards EM Series vacuum pump. Please refer to the maintenance schedule for recommended maintenance Edwards offers oils, service kits and component spares for complete pump/accessory overhaul and blade * Remember that corrosive or abrasive applications, or the use of gas ballast, may increase the required frequency of service activities. The condition of oil used in mechanical pumps deteriorates over time and by contamination from process gases and byproducts, indicated by a progressive change of oil color. Regular replacement of oil will minimise wear and tear on contacting parts and prolong good vacuum Edwards recommends regular checks on the oil colouration and replacement every 3,000 hours (4 months) depending on application. Discontinue operation, overhaul Regular cleaning of the vacuum pump to remove process deposits and replacement of the seals to prevent oil and vacuum leaks is essential to maintaining high performance of the product, as well as a clean, safe operating environment. A clean and overhaul kit contains all the parts needed for routine cleaning of your pump. Blade (vane) replacement Blades (vanes) on a rotary pump will wear during normal operation. Edwards recommends replacing them every 30,000 hours (40 months), or as your process conditions dictate. A blade kit contains a full set of blades and typically is used in conjunction with a clean and overhaul If accessories are fitted to your pump, they too will require regular checks and maintenance. A blocked dust filter, for example, can significantly reduce the efficiency of a pump. Edwards cares about the health and safety of people and the environment. Please remember to dispose of used or contaminated oil, cleaning solutions and components responsibly and safely.
