Positive Displacement Pumps
These pumps are often thought of as high-pressure pumps. Their
positive displacement of fluid and fixed volume are the result of
the fluid being mechanically moved through their pump passage on a
regular cycle. This means that regardless of the system they
discharge into, the pressure and volume will remain constant. The
power of the driving device and its speed, limit the volume and
pressure.Positive Displacement pumps:Flow rates of GPD, CC/min to
100 GPM typically.Discharge pressures of a 1 to 1000 PSI.Low speed
and fixed volume per cycle, they handle very viscid fluids
well.Smaller than centrifugal pumps.Quiet, do not ad much heat to
the fluid, suitable for shear sensitive fluids.Diaphragm pumps can
easily pass solids, stringy and fibrous foreign matter. Are made in
materials from CI to Titanium and PP, PVDF and PPS engineering
resins.
