This enables the condensate to return more rapidly to the boiler feed unit or condensate vacuum unit. This reduces energy consumption and cuts boiler room operating costs. Performance of heating units can be significantly improved as well.

Vacuum Pumps - an overview | ScienceDirect Topics

Vacuum systems consist of vacuum pumps and tanks mounted on a skid or truck. The vacuum pump creates a vacuum in the tank and the oil moves directly through a hose or pipe to the tank from the skimmer or the source of the oil. The oil does not go through the pump, but moves directly from its source into the tank.
