PCP SYSTEM

A progressive cavity pump is a type of positive displacement pump and
is also known as a progressing cavity pump, progg cavity pump,
eccentric screw pump or cavity pump. It transfers fluid by means of
the progress, through the pump, of a sequence of small, fixed shape,
discrete cavities, as its rotor is turned. This leads to the
volumetric flow rate being proportional to the rotation rate
(bidirectionally) and to low levels of shearing being applied to the
pumped fluid. Hence these pumps have application in fluid metering and
pumping of viscous or shear-sensitive materials. The cavities taper
down toward their ends and overlap with their neighbours, so that, in
general, no flow pulsing is caused by the arrival of cavities at the
outlet, other than that caused by compression of the fluid or pump
components.
