In general, traditional schemes, most of them use: oil booster pump (oil diffusion pump) + mechanical booster pump (Roots pump) + front crude pump (slide valve pump, rotary vane pump, reciprocating pump, water ring pump...) The configuration mode of;

With the emergence and maturation of dry vacuum pumps, a dry pump can be used in most process conditions.
