Positive Displacement Pumps

Positive displacement pump types include: gear, lobe, piston, diaphragm, peristaltic, screw, progressive cavity, hydraulic and many others. Their advantages are:

• Pump high viscosity (thick) fluids with ease, more efficiently than centrifugal.
• Pump liquefied gases, shear sensitive fluids and medium viscosity liquids as well
• Maintain consistent output flow rates with varying inlet and discharge pressure conditions
• Most are self priming and can handle liquids with entrained vapor
• Available in Mag Drive seal-less configurations

Positive Displacement pumps operate by using a rotary, reciprocating, or diaphragm method of drawing fluid into the pumping chamber at the inlet and pushing it through a discharge outlet.  Positive Displacement pumps move fluid at a constant rate regardless of pressure conditions, and they are typically the preferred choice for low to moderate flow rates at higher discharge pressures.
