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.
The Progressing Cavity Pump and it’s Geometry • A progressing cavity (PC) pump, or a single screw pump, is a positive displacement pump and therefore a fixed volume is displaced with each revolution of the pump’s Rotor. • The Rotor forms a single helix (like
The progressive cavity pump is an excellent choice as the fluid viscosity increases beyond the efficient range of centrifugal pumps. Rotors are typically 4140 tool or 316-SS austenitic steel that is chrome plated, but they can also have chrome oxide, carbide and ceramic coatings. The rotor will usually be solid metal, but some manufacturers
Along with stators, rotors are key components in Progressive Cavity (PC) pump function.WestCoast Rotor is a market leader in replacement PC pump rotor manufacturing. We produce numerous standard pump rotors, and have the capabilities to create application specific rotors in
The quality of stator and rotor can directly or indirectly determine progressive cavity pumps service lives. Specialized in pump stator and rotor, Subtor has designed four types of stator and rotor for you to choose—type A, type B, type D and type P.
and they demonstrated that a progressing cavity pump with clearance between rotor and stator could work. This makes possible the use of metallic material, such as steel, bronze, and alloy. Any of these materials could be specified, but the question would be the performance of a pump with such a material.
Oct 01, 2000· The displacement of a progressive cavity pump depends on three design features: Rotor diameter. Rotor eccentricity. Stator pitch. The pump’s pressure rating depends on the number of stages. By repeating the identical, single-helical con-figuration, increasing the length of the stator and rotor increases the number of stages (Fig. 2).
COMPENSATING ECCENTRIC MOTION IN PROGRESSING CAVITY PUMPS Background The progressing cavity pump developed by Dr. Rene Moineau in France over 60 years ago has proven to be one of the most enduring and innovative mechanical inventions in history. The interaction of a single helical rotor rolling eccentrically within a double-threaded internal
The basic progressing cavity pump components consist of a rotor and a stator the configuration of which is given below. The Progressing Cavity Pump (PCP) is a rotary positive displacement pump consisting of two (2) components. A single external helical rotor rotates eccentrically inside an internal double helical stator of the same minor diameter
The PCP pump is a progressive cavity pump. This name explains how it works. There is a free space between the stator and the rotor (cavity) which, during the rotation of the rotor, will propagate from the suction of the pump to its discharge. The cavity will move by wrapping around the rotor and progressively move towards the exit.
Quality Progressive cavity pumps,we have a wide range of retrofit spares to offer for brands like NETZSCH®, Roto pump®, psp, and other global brands as well. Manufacturing materials : DEEPA PUMPS Rotors are manufactured in stainless steel with induction deep hardening. They offer better abrasive and corrosive resistance.
A progressing cavity pump adapted for use in pumping liquid/solid mixtures with a solid content of about 50% has a single start helical rotor and a two start helical stator bore. The ratio of the eccentricity of the rotor to its minor diameter is about 1:4.9. The ratio of the eccentricity of the rotor
How do progressive cavity pumps work? The rotor helix is shaped off-set to the stator creating cavity spaces in the assembly which are formed by temporary seals as the rotor contacts the surface of the stator. As the rotor begins to move in an eccentric fashion, the cavities form, draw in product and are 'progressed' along the assembly and
How Progressing Cavity Pumps work: Progressive Cavity Pumps have similar characteristics to rotary or reciprocating pumps, such as piston, diaphragm, lobe, and screw pumps. They are also known as an eccentric screw pump due to the motion of the rotor. The one common feature being the sealed cavities with operational similarities like being
The main functional components of a progressive cavity pump are the rotor and the stator. The rotor (5) is a circular cross section single-start screw with a very large pitch. The stator (4), which is normally made from rubber, is vulcanised inside a steel pipe. The stator has a hollow core in the shape of a two (or three) start screw, with the

Equipment Pump Sizing Installation Commissioning Troubleshooting Winpetro Program. Introduction A PCP. consists of a single rotor which rotates inside stator, the rotor is made from high strength steel and stator from elastomer. When the rotor is
INOXPA is a progressive cavity pump supplier, offers Kiber NTE progressive cavity pump, ideal for pumping grapes. Friction between the rotor and the stator creates vacuum in the inlet area thereby helping the entry of the product into the pump. The turning motion of the rotor makes the cavities between the rotor and the stator move forward and
In most progressing cavity pumps, the stator is made of an elastomeric material while the rotor is made of a rigid material. Progressing cavity pumps are also available with rigid stators that fit on the rotor with a clearance. Advantages of progressing cavity pumps are found in the wide variety of fluids, flow rates and pressures they can serve.
Functioning of a progressing cavity pump. The delivery principle is based on a rotor which turns in an oscillating motion within a fixed stator. The coordinated, spiral geometry of both components creates delivery chambers in which the medium is transported from the suction to the pressure side.
