This is an oil rotary pump that has improved drive noise reduction, steam exhaust resistance, and exhaust performance due to a complete redesign.
The E2S series is a two-stage rotary vane type oil rotary pump (oil pump). It features a completely revamped design and offers excellent cost performance. <E2S Series Features> 〇 High Exhaust Capacity: The E2S has nearly 10% better exhaust performance compared to the conventional E2M, even with the same motor rating. 〇 Oil Box: Utilizes extrusion molding. Improved airtightness and the incorporation of heat dissipation fins enhance cooling effectiveness. 〇 Reduced Operating Noise: By redesigning the internal mechanisms and changing the materials used, the E2S series operates more quietly than conventional pumps, achieving <60dB for the E2S series compared to <65dB for the E2M series. 〇 Steam Exhaust Resistance: With the use of materials that excel in steam resistance and a mode selection feature, the E2S can achieve a maximum steam resistance of 20mbar (E2S45). It lubricates the inside of the pump with a constant oil supply pressure, ensuring stability across all vacuum pressure ranges. 〇 Oil Filter: Extends the life of the oil and protects sealing materials from contamination and dirt. The recommended replacement interval under clean operating conditions is approximately 12 months.

basic information
Depending on the exhaust speed, you can choose from three models (E2S45, E2S65, E2S85). The oil used is mineral oil, the cooling mechanism is air-cooled, and the power supply is 200V three-phase. Additionally, by selecting various accessories (options), it can accommodate operation in various environments. - Temperature safety switch - Oil level switch - Dust filter - Catch pot - Chemical trap The E2S series can be connected to the mechanical booster EH series. By combining them, the pump's exhaust speed and ultimate pressure are improved. For product details, please view the catalog from [PDF download] or feel free to contact us.
