Pfeiffer Vacuum expands the OktaLine ATEX collection

Roots pumps from Pfeiffer Vacuum’s OktaLine are good 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 strain surge resistance of PN 16, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is ruled out as a result. เกจวัดแรงดันลมดิจิตอล vary from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or heat therapy.
As a result of the expansion of the sequence, pumping speeds range from 280 to 8,one hundred m3/h. Depending on the appliance, there is a choice between tools class 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible with out flame arresters. This implies that, effectively, the full pumping velocity of the pump is on the market.
The pumps are suitable for universal use due to their variable differential stress and flexible rotational pace. All pumps can be utilized at ambient temperatures ranging from -20 °C to + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extraordinarily low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak factors if it comes to strain surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant up to 1600 kPa. Due to their magnetic coupling, there is no risk of zone entrainment. The built-in temperature sensor protects towards thermal overload and monitors the gas temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent decrease operating costs and significantly lowered maintenance prices. OktaLine Roots pumps can additionally be operated and not using a bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors signifies that replacement on site is fast and straightforward.
