progressive cavity pump is a type of positive displacement pump and is also known as a progressing cavity pumpprogg cavity pumpeccentric 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. As one cavity diminishes another increases, the net flow amount has minimal variation as the total displacement is equal

Application Progressive Cavity Pumps

Application Progressive Cavity Pumps ideal for applications in agriculture, ceramics, chemicals, biochemicals, construction, dyeing, paints, electroplating, environmental technology, fish processing, food, beverages, bakery dough and fillings, mining, inorganic minerals, oil and natural gas production, offshore technologies, cosmetics, petrochemicals, pharmaceuticals, pulp and paper, shipbuilding, sugar refining, water and wastewater treatment, textiles, glues, adhesives, mastics and sealers in the transportation and construction markets.


Feature Seepex Pump
