Used EDWARDS EH250 / E2M40 #71250 for sale

EDWARDS EH250 or E2M40 is an industrial rotary pump designed for applications requiring low or medium vacuum. The pump features a single stage sliding vane design and requires a liquid-cooled motor to operate. It has a maximum displacement of 40 m3/h and a maximum speed of 420 rpm. The EH250 has a single inlet and outlet port and can operate with a variety of gas systems. The EH250 has a free intake capacity which provides a more stable long-term operating condition. The EH250 is designed to handle transfers of chemically aggressive and corrosive fluids. The EH250 has an oil-lubricated rotors set within a cartridge assembly. Its rotors, composed of low-pressure aluminum, are designed to minimize friction and thermal loading. Additionally, the EH250 is equipped with oil-mist lubrication, which helps to reduce bearing wear and extends pump life. The EH250 is powered by a two-pole motor which limits noise levels and vibration. The EH250's advanced design ensures exceptionally smooth operation, including low pulsation rates. The EH250 is easy to maintain and has a high uptime as well as low cost of ownership. The pump's internal labyrinth seals ensure a long service life and can be easily replaced, extended pump operation. The EH250 is also fitted with a spring-loaded V-ring seal which minimizes air loss, allowing the pump to operate at lower temperatures. The EH250 is ideal for vacuum-related industrial processes with its robust and reliable design. With its reduced noise and high efficiency, the EH250 operates in a wide range of applications, including filtration, agitation and distillation. The EH250 is designed to remain reliable under the most demanding conditions. Its simple design and robust construction makes it a great choice for heavy duty operations.
