It is equipped with air ballast valves to meet the vacuum requirements of different customers and the ability to handle water vapor
Explosion-proof mark: ExdIBT4
This pump adopts explosion-proof, burning, intrinsically safe composite explosion-proof technology, safe and reliable
FAQ
QIt is necessary to prevent oil from being poured into the vacuum container during shutdown
A
DVPF-4 explosion-proof two-stage rotary vane vacuum pump is equipped with anti-reverse suction valve, which can effectively prevent oil from being sucked into the vacuum container during shutdown, ensuring equipment safety and service life.
QWater vapor needs to be processed and the vacuum degree can be adjusted
A
The pump is equipped with a gas ballast valve, which can meet the requirements of different vacuum degrees and can effectively handle water vapor. The ultimate pressure is less than or equal to 0.005mbar when the gas is closed and less than or equal to 0.05mbar when the gas is opened.
