  • Steam Ejector Pumps And Ejectors & Steam Ejector Theory
    by a properly designed throat or venturi will economically make use of high pressure fluid to compress from a low pressure region to a higher pressure. This change from pressure head to velocity head is the basis of the jet vacuum principle. Ejectors are generally categorized into one of four basic types
  • Water Aspirators: Cheap Pumps With Environmental Impact & High Operating Costs
    Water aspirators are a common way of creating a low strength vacuum for many standard laboratory applications. Their simple design employs water running through a narrowing tube to create a reduced pressure via the Venturi effect. The pump's performance is dependent upon the temperature
  • Flow Measurement
    devices are there to choose from? There are types that create an obstruction in the pipe and measure the differential pressure across this obstruction. This includes the age-old orifice plate and venturi meter. Does your customer really want to pay for this pressure drop for the life
  • Flow Sensors
    a secondary measuring system -- flow is determined based on a pressure-flow relationship. flow sensors are the most widely used of the differential pressure flow sensors; others being nozzle, venturi, and flow tube. Generally, an orifice sensor
  • Vacuum systems accelerate chip production
    explains. The challenge of late, says Buerkel, has been to design vacuum systems that meet OEM demands for higher speeds. Parker has recently introduced several fast-acting devices such as the MC3 high-speed integrated venturi, VA01 vacuum valve for centralized vacuum systems, and pressure sensors
    . Their low coefficient of friction diminishes particle shedding. The XGC system uses three abatement stages to thoroughly scrub highly toxic and pyrophoric gases from process effluent gas streams. The three stages are a spray chamber, an Eductor venturi stage, and the Waterweb mesh. The mesh system
  • Which Pump Is Right for Me? Pushing Through a Host of Factors to Select the Right Pump
    for priming, use either a compressor/venturi priming device, diaphragm priming device, or vacuum unit. The vacuum unit is the fastest prime due to its air handling capacity. Q: Why is there such a price difference between pumps? After all, aren't all pumps basically the same?. A: There is a vast
