U.S. Heat Treater Orders Vacuum Pump
Metallurgical High Vacuum (MHV) of Fennville, Mich., shipped a Survivor™ model HD300 vacuum pump to a U.S.-based heat treater. The pump, which will be used on an Ipsen-built furnace, provides longer life because of its robust construction and filtration that minimizes acids and contaminants. MHV’s Survivor vacuum pumps use a proven oil-sealed rotary piston design for excellent reliability, even in demanding operating conditions encountered in heat treating. Their pressurized oil lubrication increases pump life significantly by filters that clean the oil of particulates and acids. Clean oil is forced into the critical hinge bar/piston slide tang interface. The eccentric bearing bands are also pressure lubricated.
