Roots vacuum pumps series HV/BP complete with bypass valve are mainly used coupled to our lubricated vacuum pumps to speed up pumping down times and to achieve vacuum level up to 0,01 mbar abs. Bypass valve allows to start the Roots pump at the same time as the vane vacuum pump, protecting the Roots pump from any operation at high pressure. |
