  • Living in a World of Pressure and Vacuum Pumping Application

    Applications: Typical applications involving pumping from a vessel under high vacuum are: (1) soybean oil processing; (2) removing the water vapor from syrups and candies; (3) degassing transformer oils; and (4) dry cleaner stills. (Note: It is not necessary to shy away from an application involving 28” or 29” Hg of vacuum. By understanding the system and how to locate the pump, this type of application can be handled satisfactorily.)

  • Vacuum sewer - Wikipedia

    A vacuum sewer or pneumatic sewer system is a method of transporting sewage from its source to a sewage treatment plant. It maintains a partial vacuum, with an air pressure below atmospheric pressure inside the pipe network and vacuum station collection vessel. Valves open and reseal automatically when the system is used, so differential pressure can be maintained without expending much energy pumping. A single central vacuum station can collect the wastewater of several thousand individual home

  • Vacuum unit pressure control - DigitalRefining

    However, pressure control is necessary in some cases to intentionally avoid low pressure or to raise the column operating pressure to reduce the load on other crude unit equipment. Good pressure control allows the first-stage ejector gas load to be maintained constant in spite of variations in the process load from the top of the vacuum column.

  • Vacuum Pressure: What is it how do you measure it?

    The vacuum pressure transducer gives an increased positive voltage output proportional to decreasing pressure (increasing vacuum). The absolute pressure transducer gives an increased positive voltage output proportional to increasing pressure (decreasing vacuum). Example. Vacuum Transducer Range: 0 to 14.7 PSIV Output: 0 to 5 VDC. Absolute Transducer Range: 0 to 14.7 PSIA Output: 0 to 5 VDC . Differential Pressure.
