Zone entrainment of explosive gases is ruled out as a result. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial applications such as vacuum furnaces or heat treatment.
As a result of the expansion of the series, pumping speeds range from 280 to 8,100 m3/h. Depending on the application, there is a choice between equipment category 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible without flame arresters. This means that, effectively, the full pumping speed of the pump is available.
The pumps are suitable for universal use due to their variable differential pressure and flexible rotational speed. All pumps can be used at ambient temperatures ranging from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and achieve extremely low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak points if it comes to pressure surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there is no risk of zone entrainment. The integrated temperature sensor protects against thermal overload and monitors the gas temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine's magnetic coupling achieves up to 20 % lower operating costs and considerably reduced maintenance costs. OktaLine Roots pumps can also be operated without a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that replacement on site is quick and easy.
