An expanded line of explosion-proof Roots pumps
Designed in accordance with the ATEX Directive (2014/34/EU1 and/or 1999/92/EC) with pressure-surge resistance of PN 16, Roots pumps from the OktaLine (photo) meet the very highest explosion-protection requirements. This series of pumps is now expanded, with pumping speeds ranging from 280 to 8,100 m3/h. With their magnetic coupling, OktaLine pumps are hermetically sealed and achieve extremely low leak rates of 10–6 Pa m 3/s. Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20% lower operating costs and considerably reduced maintenance costs, says the company. The magnetic coupling eliminates the need for shaft seals. OktaLine ATEX pumps are pressure-surge resistant up to 1,600 kPa. — Pfeiffer Vacuum GmbH, Asslar, Germany
