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 . Nemo r progressing cavity pumps have a very broad application range and are used in all branches of industry for the continuous pressure stable gentle and low pulsation conveyance of almost any substance one advantage for the operator is that such a valveless positive displacement pump is also capable of transporting stringy material safely. The progressive cavity pump is an extremely versatile pump that can be used in many different pumping applications it offers all the advantages of a positive displacement pump and is specially designed for abrasion resistance in tough pumping applications. Enhance your performance in the industry with progressive cavity pumps from global manufacturers pcm submit a sales enquiry today or simply browse intelligent designs to suit sectors from food cosmetics to oil gas. Progressing cavity pumping pcp systems derive their name from the unique positive displacement pump that evolved from the helical gear pump concept first developed by rene moineau in the late 1920s
