Used LEYBOLD HERAEUS E225 #75086 for sale

LEYBOLD HERAEUS E225 is a high efficiency oil sealed rotary vane vacuum pump which can handle a wide range of capacities ranging from 200 to 900 cubic feet per minute. It is designed to be used in a wide variety of industrial and commercial applications including chemical, medical, semiconductor, and industrial process equipment. E225 features a powerful, two-stage, rotary vane pump design with an 80 mm maximum displacement rotor. This allows the pump to achieve a peak pressure of 0.25 mbar absolute and will operate at a continuous flow rate of up to 900 CFM. The pump is proven to be up to 70% more efficient compared to conventional oil-sealed rotary vane pumps, and its efficiency is further improved due to its automatic parasitic power compensation and oil-bearing design. LEYBOLD HERAEUS E225 uses a displacement system powered by a 230V three-phase asynchronous motor, and is designed to have a motor power rating of up to 22 kW (30 HP). In addition, it boasts a variable speed feature with a digital frequency inverter which allows for precise and smooth operation. This digital frequency inverter also supports a built-in overload protection system to ensure optimal safety. The pump is constructed out of aluminum alloy, stainless steel, and polyurethane components which offer a wide range of features including dust filter, oil level control, thermostatic protection, vacuum valve, and cooling systems. The dust filter is designed to keep solid particles suspended in the oil away from the gas stream, while maintaining a low temperature of the oil. The oil level control protects the pump from operating with too low an oil level, while the thermostatic protection feature shuts off the pump in temperatures above 85°C to prevent any damage due to excessive heat. Vacuum valve helps reduce oil backflow, and the cooling system helps to maintain a stable pressure throughout the pump structure. In addition, E225 pump is equipped with a self-pressurizing crank chamber which is designed to provide optimal lubrication for the bearings and ensures an optimal cooling due to the difference between the atmospheric and scavenging pressures. LEYBOLD HERAEUS E225 pump also boasts a comprehensive service package for all its vacuum products, which provides comprehensive maintenance, periodic inspections, and emergency repairs. This ensures that the pump can be operated with maximum efficiency and reliability.
