Pfeiffer OktaLine Roots pumps with a magnetic coupling are ATEX certified for use in potentially explosive applications. The hermetically sealed pumps have leakage rates of less than 7.5 x 10-9 Torr L/sec. and resist pressure surges up to 1,600 kPa (12,000 Torr); the magnetic coupling prevents gas exchange between process-related internal and external atmospheres. The pumps allow technically dry operation.
