  • Remediating Sustained Casing Pressure by Forming a Downhole Annular Seal with Low-Melt-Point Eutectic Metal
    Then 200 - psi air pressure was applied with the diaphragm pump , which also held for 1 hr.
  • Practical Handbook of Grouting: Soil Rock and Structures Complete Document
    Generally, centrifugal and diaphragm pumps provide the lowest pressures, seldom generating more than about 200 psi (14 bars).
  • Toxicity of indoxacarb to two species of predacious mites and a predacious Mirid
    Applications were made with a diaphragm - pump hand-gun system that delivered 75 g AI in 1350 litre ha−1 at 1380 kPa ( 200 psi ).
  • Biosolids Treatment Processes
    After water release appears complete following the initial filling period, pumping is stopped and the diaphragm cycle is initiated. The diaphragm pressure is applied, using either air or water on the reverse side of the diaphragm, and pressures up to 1380–1730 kPa ( 200 –250 psi ) are applied to the biosolids for additional dewatering.
  • Hydrogen Production For Fuel Cells Via Reforming Coal-Derived Methanol
    To have a reliable liquid pump in a high pressure environment, a solenoid diaphragm derived metering pump , Figure 25, was purchased to replace the gear pump as the liquid driver. The metering pump has the ability to drive the feeding liquid at a constant flow rate from atmospheric pressure to a pressurized pipeline at 200 psi .
  • HYDROGEN PRODUCTION FOR FUEL CELLS VIA REFORMING COAL-DERIVED METHANOL
    To have a reliable liquid pump in a high pressure environment, a solenoid diaphragm metering pump was purchased to replace the gear pump as the liquid driver. The metering pump has the ability to drive the liquid at a constant flow rate from atmospheric pressure to a pressurized line at 200 psi .
  • Diaphragm Slush Pump
    To accelerate the accumulation of data from pump operations, the two experimental diaphragm pumps were removed from field service, and one was installed at a test installation in Houston, Tex. This unit was operated on a continuous round-the-clock schedule; the pump performed at approximately 200 strokes per minute at a discharge pressure of 1,500 psi .
  • Diaphragm Metering Pumps for Corrosive Liquids
    Operational temperatures range from 125 F to 200 F (52 C to 93 C) with maximum pressures from 150 to 3,000 psi (11 to 210 bar). When choosing between a hydraulically or mechanically actuated diaphragm metering pump , operators must con- sider the specific needs of their operations.
  • Hanford tank initiative cone penetrometer stand alone grouting module
    … OD CP Push Pipe Sacrificial Grout Mini TiDs with O-rinqs 61 m ( 200 ft) length of … OD by 7.9 mm (5/16 in.) ID Grout Tube Diaphragm Pump : ARO Model 666053-388 or equivalent Air Compressor with Pressure Regulator: 150 psi capacity .
  • MEMBRANE SEPARATIONS IN ALCOHOL PRODUCTION *
    Pressures up to 200 psi could be applied by compressed nitrogen gas, with temperatures up to 100°C possible. … areas up to 0.75 ft2,had spacesabove the membranes of about 1 mm, and were filled with a variety of turbulence-producing materials, were also employed, with pressures up to 100 psi applied by a diaphragm pump and circulation effected by …
