E2M Two Stage RVP
The robust mechanical oil-sealed EM series pumps have speeds between 0.7 and 275 m3/hr (30 and 206 CFM). They are quiet, small, and equipped with high dependability, sophisticated lubricating circuits, and accessories to meet specialized application requirements.
EM goods cater to two main areas of use.
For your turbomolecular pump, the E2M0.7-2.5 and E2M18/28 are the perfect companions in scientific and lab settings.
E2M18/28, E2M40/80, and E2M175/275 provide incredibly durable solutions for demanding applications in industrial settings.
