All of the lubricated rotary vane vacuum pumps from Vaccum Pumps UK may run continuously within certain pressure ranges, or connected to containers to be emptied, whose volume is appropriately sized for the pump flow rate. Long-term use at atmospheric pressure is not recommended.
The lubrification allows these pumps to intake water vapour. To avoid condensation of the water vapour, the lubricated rotary vane vacuum pumps are equipped with the gas ballast, a system that introduces air in the compression stage and changes the vapour saturation pressure thus avoiding condensation. In the WR pump version, the gas ballast system is improved and reinforced.
