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.

Since the pump is waterproof, it can also be used as a shut-off valve. It is therefore very easy to obtain a relatively accurate dosing, without pulsations and without the need to add a valve, just by controlling the rotation of the motor.

Note: If the discharge pressure increases or the stator wears out, the leakage rate in the pump will increase and the total flow will be lower than the theoretical flow.

As a consequence, the rotor and stator will not be sealing between pump inlet and outlet, the cavities in the pump will enable leakage and the PC pump will no longer be pumping.

An eccentric screw pump is reversible, but it has a preferred operating direction: with the discharge through the free end of the rotor which is the opposite side to the motor.

the density of the pumped fluid, the pressure drop at the maximum flow rate predicted in the supply pipes from the storage tank, as well as the vapor pressure.

There are a few exceptions to this, as example for dosing pumps for which the ratio can be rather different, or for extended single stage pumps for which it is only possible to know by opening the pump and counting the cavities.

PCM is the original manufacturer of Progressive Cavity Pumps. Founded by Rene Moineau, who in 1930 published a pioneering dissertation that paved the way for the progressive cavity pumps. Today, PCM continues to create and innovate new products and services to meet a wide variety of market needs and applications.

The Technology In a progressive cavity pump a rotor turns inside a stator, producing a steady flow based on drive speed. PCP’s are ideal for pumping viscous, particulate, abrasive, and fragile products. They are equally suited to applications that require an artificial lift, such as oil filed applications. Changing the geometry or shape of the rotor governs the pumps output. PCP’s can be designed to deliver a precise and continuous flow of even the most difficult materials.

A progressing cavity pump is a type of positive displacement pump and is also known as a progressive 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.

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. This design results in a flow with little to no pulse.

A progressing cavity rotor and stator can also act as a motor (mud motor) when fluid is pumped through its interior. Applications include directional well drilling.

The progressing cavity pump normally consists of a helical rotor and a twin helix, twice the wavelength helical hole in a stator. The rotor seals tightly against the stator as it rotates, forming a set of fixed-size cavities in between.

The principle of this pumping technique is frequently misunderstood. Often it is believed to occur due to a dynamic effect caused by drag, or friction against the moving teeth of the screw rotor. In reality it is due to the sealed cavities, like a piston pump, and so has similar operational characteristics, such as being able to pump at extremely low rates, even to high pressure, revealing the effect to be purely positive displacement. The rotor "climbs" the inner cavity in an orbital manner (see pump).

At a high enough pressure the sliding seals between cavities will leak some fluid rather than pumping it, so when pumping against high pressures a longer pump with more cavities is more effective, since each seal has only to deal with the pressure difference between adjacent cavities. Pump design begins with two (to three) cavities per stage. The number of stages (currently up to 24) is only limited by the ability to machine the tooling.

The rotor takes a form similar to a corkscrew, and this, combined with the off-center rotary motion, leads to the alternative name: eccentric screw pump.

Different rotor shapes and rotor/stator pitch ratios exist, but are specialized in that they don"t generally allow complete sealing, so reducing low speed pressure and flow rate linearity, but improving actual flow rates, for a given pump size, and/or the pump"s solids handling ability.

In operation, progressing cavity pumps are fundamentally fixed flow rate pumps, like piston pumps and peristaltic pumps, and this type of pump needs a fundamentally different understanding than the types of pumps to which people are more commonly introduced, namely ones that can be thought of as generating pressure. This can lead to the mistaken assumption that all pumps can have their flow rates adjusted by using a valve attached to their outlet, but with this type of pump this assumption is a problem, since such a valve will have practically no effect on the flow rate and completely closing it will involve very high pressures being generated. To prevent this, pumps are often fitted with cut-off pressure switches, rupture discs (deliberately weak and easily replaced), or a bypass pipe that allows a variable amount of a fluid to return to the inlet. With a bypass fitted, a fixed flow rate pump is effectively converted to a fixed pressure one.

At the points where the rotor touches the stator, the surfaces are generally traveling transversely, so small areas of sliding contact occur. These areas need to be lubricated by the fluid being pumped (hydrodynamic lubrication). This can mean that more torque is required for starting, and if allowed to operate without fluid, called "run dry", rapid deterioration of the stator can result.

While progressing cavity pumps offer long life and reliable service transporting thick or lumpy fluids, abrasive fluids will significantly shorten the life of the stator. However, slurries (particulates in a medium) can be pumped reliably if the medium is viscous enough to maintain a lubrication layer around the particles and so protect the stator.

Specific designs involve the rotor of the pump being made of a steel, coated with a smooth hard surface, normally chromium, with the body (the stator) made of a molded elastomer inside a metal tube body. The elastomer core of the stator forms the required complex cavities. The rotor is held against the inside surface of the stator by angled link arms, bearings (immersed in the fluid) allowing it to roll around the inner surface (un-driven). Elastomer is used for the stator to simplify the creation of the complex internal shape, created by means of casting, which also improves the quality and longevity of the seals by progressively swelling due to absorption of water and/or other common constituents of pumped fluids. Elastomer/pumped fluid compatibility will thus need to be taken into account.

In 1930, René Moineau, a pioneer of aviation, while inventing a compressor for jet engines, discovered that this principle could also work as a pumping system. The University of Paris awarded René Moineau a doctorate of science for his thesis on “A new capsulism”. His pioneering dissertation laid the groundwork for the progressing cavity pump.

Pump Will not StartRotor & Stator Adhesion.Adhesion between Stator and Rotor due to prolonged period of inactivity. Lubricate rotor and stator with glycerin, or inert oil.

Fluid TemperatureClearances between rotor and stator are minute. If fluid is outside pump design range, stator will suffer thermal expansion and burn against the rotor

Frozen FluidTemperature is too low with fluid freezing within pump. Ensure pump is protected from elements, drain when not in use or install trace heating.

Inverter Settings / WiringCheck starting torque of motor is correct as on initial startup power absorbed can be high meaning, if the torque is not set correctly on the inverter, it will not start the pump.

If forced air cooling is fitted to the motor and is not wired (requires wiring seperately to the motor) then the pump may start and trip as it is not receiving sufficient cooling from the external cooling fan.

Mud Pumps come in both electric and gas / diesel engine drive along with air motors. Most of these pumps for mud, trash and sludge or other high solids content liquid dewatering, honey wagon and pumper trucks. Slurry and mud pumps are often diaphragm type pumps but also include centrifugal trash and submersible non-clog styles.

WARNING: Do not use in explosive atmosphere or for pumping volatile flammable liquids. Do not throttle or restrict the discharge. Recommend short lengths of discharge hose since a diaphragm mud pump is a positive displacement type and they are not built with relief valves.
