  • Positive Displacement Pump and Turbine Pump Attributes to Consider for Liquid-Based Temperature Control (.pdf)
    initial cost often times PD pumps are selected over TU pumps where flow and pressure requirements can be met by a PD pump. ./f1d59a35-1583-4495-9524-4b6e9a5e4422 Application Note. Positive Displacement Pump and Turbine. Note # AN-SP-10-3. 1.0.0. Pump Attributes to Consider for Liquid-. Based
  • Advancements in Sliding Vane Positive Displacement Pump Technology Leads to Greater Energy Savings
    displacement pumps (PD).
  • When to Use PD Pumps (Copyright Viking Pump, Inc.)
    When to use a centrifugal or a Positive Displacement pump ("PD Pump") is not always a clear choice. To make a good choice between these pump types it is important to understand that these two types of pumps behave very differently. Flow rate versus pressure By looking at the performance chart
  • Positive Displacement Vacuum Pumps
    Positive displacement vacuum pumps are designed for use with very long hoses. They are gas-transfer vacuum pumps in which a gas-filled suction chamber is separated periodically from the entrance port. Preferably, positive displacement pumps operate in the viscous flow area. In most displacement
  • Novel Piezo Motor Enables Positive Displacement Microfluidic Pump
    We present the world's smallest linear motor and its use in tiny syringe and reciprocating piston pumps for microfluidic applications. SQUIGGLE(R) motors create direct displacement pumps that achieve nanoliter precision in a pump assembly the size of a pen cap. In this design, linear motion

    ). These include harmonics of: Drive motor and pump running speed. Rolling element bearing fault frequencies. Speed increaser/reduction gear mesh. Vane pass on dynamic pumps. Reciprocation impacts on positive displacement pumps. Signal-to-noise ratio problems are rare in this frequency range due to the strong
  • Pump Basics
    illustrated with a similar curve, which clearly demarcates the relation between the liquid pumped per unit time and the increase in pressure. But curves for different pump categories have very different characteristics. Positive-displacement pumps, for example, show a flow rate virtually independent
  • Pump Basics
    ; displacement; mechanism; cylinders, and pressure. Reciprocating pumps convert rotary motion to linear motion. Pump speed in rpm determines the pumps output volume for any given combination of cylinder bore and piston stroke. Positive Displacement pumps are used to move liquids or compress gases
