For a wide range of critical applications

Positive displacement (PD) pump technology has endured decades of process challenges and substances, becoming a versatile choice among professionals for its consistent performance and robust nature. Positive displacement pumps operate by pulling in fluid, trapping a fixed amount within a chamber and then forcing it out into a discharge pipe. Because of their design, positive displacement pumps tend to have better flexibility than alternative pumping technologies when handling pressure and flow variations found in continuous or intermittent-type processes. Positive displacement pumps also operate at high efficiencies when operating conditions – such as viscosity or pressure – change, allowing them to operate at peak efficiency regardless of the conditions or environment.

PSG® is the global leader in positive displacement (PD) pump technology. Ideally suited for a wide range of critical applications, PSG offers the following:

  • Air-Operated Double-Diaphragm (AODD)
  • Diaphragm (Metering)
  • Eccentric Disc
  • Quaternary (Four-Piston) Diaphragm
  • Internal Gear
  • Peristaltic
  • Screw
  • Sliding Vane
  • Lobe
  • Reciprocating Triplex Plunger Pumps - API 674

When it comes to positive displacement pumps, the toughest choice an operator has is deciding which one will work best in their application. It’s not always a simple choice either, as positive displacement pump technologies offer many of the same benefits and varying advantages. For operators, the best positive displacement pump will balance a combination of fluid properties, system layout, and performance function. Positive displacement pump technologies offer essential functional and performance benefits that move liquids effectively and optimally.
