Roots pumps from Pfeiffer Vacuum’s OktaLine are ideal for use in processes in probably explosive environments or for evacuating explosive gases. Designed in accordance with the ATEX Directive (2014/34/EU1 and/or 1999/92/EC) with pressure surge resistance of PN sixteen, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is ruled out consequently. เกจวัดแรงดัน250bar vary from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or warmth remedy.
As a result of the enlargement of the sequence, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the applying, there is a selection between equipment category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible without flame arresters. This signifies that, effectively, the full pumping velocity of the pump is on the market.
The pumps are appropriate for common use as a outcome of their variable differential pressure and versatile rotational speed. All pumps can be utilized at ambient temperatures starting from -20 °C to + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and achieve extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, that are inherently weak factors 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 danger of zone entrainment. The integrated temperature sensor protects against thermal overload and monitors the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent lower operating prices and considerably decreased upkeep prices. OktaLine Roots pumps can be operated and not using a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that alternative on web site is quick and straightforward.
