E2M28 Two-stage rotary vane pumps
Modern two-stage oil-sealed rotary vane pumps
Two-stage oil-sealed rotary vane pumps are highly efficient positive
displacement pumps in which the conveyed gases come into contact with
oil during operation. The oil acts as both a sealant and a coolant,
ensuring optimal performance and long life.
These pumps work with a two-stage compression system and offer a high
pumping speed with a low final pressure at the same time. They are
ideal for a wide range of applications in industry, chemical,
pharmaceutical, and food processing.
E2M Two-Stage Pumps
The E2M series offers pumps with capacities ranging from 0.7 to 275
m³/h (30 to 206 CFM). These pumps are known for their compact design,
low noise level and high reliability. They have advanced oil
circulation systems and accessories specially designed for various
applications.
In scientific and laboratory applications, the E2M0.7-2.5 and E2M18/28
models work perfectly in combination with turbomolecular pumps. In
demanding industrial environments, the E2M18/28, E2M40/80 and
E2M175/275 models offer robust and durable solutions.
Key features and benefits
