As the metallic stator progressing cavity pump (PCP) operates with the stator and rotor in clearance fit, the slippage between cavities has a significant influence on the pump performance. In this paper, an analytical model is developed for the flow in the metallic stator PCP. Based on the analyses of the meshing movement and the clearance geometry inside the pump, the slippage through the ...
The Nova Rotors DN/JN series progressive cavity pump is excellent at handling viscous and non-viscous fluids with or without solids in suspension. There are various models of this helical rotor pump, the largest is capable of achieving flow rates up to .
Progressive cavity pump operation. A progressive cavity pump displaces a fixed volume of liquid with each revolution. The rotor (a single helix design) rolls "eccentrically" within the stator (a double helix design). This design combination creates cavities, or voids, which move toward the pump's discharge end as the rotor turns.
We offer an extensive line of downhole progressing cavity pumps for varying applications and downhole conditions. Using advanced manufacturing technology with modern production techniques like finite machining, we maintain the rotor profile plating to ensure the design performance is always achieved.
Progressive cavity pump - Wikipedia. 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.

Abstract:. Pumping Abrasives with Progressive Cavity, Helical Rotor, Eccentric Screw Pumps. Often used to pump slurries, helical rotor pumps (also known as progressivity cavity pump, eccentric screw pump, mono pump) use a spiral rotor to move a chamber full of product through the pump.
WestCoast Rotor Inc. has been manufacturing parts to fit the Moyno® brand pumps since 1982. Our focus has always been solely on progressing cavity pump parts with the strong detection to the highest quality and workmanship.
The rotor of the progressive cavity pump is specially made of stainless steel or hardened alloy steel, and feature a chrome plating, which offers excellent resistance against abrasive and corrosive materials. MXQ progressive pumps have rotors made of C45 hard chrome tool steel, 1.4571 SS 316, and 1.4462 SS. ...
The progressive cavity pump principle is ideal for handling liquids that can be slurries, viscous, shear sensitive, 2 or 3 phase mixtures or when applications require, significant suction lift capabilities. The heart of the Progressive Cavity vpump is the rotor and stator.

Our Progressive Cavity Pump comprises a metallic rotor with a helical profile, as well as an elastomeric stator with a double helix profile. When the rotor is assembled within the stator, a series of sealed cavities are formed inside the pump, each of identical size and profile. When the pump is running, the rotor turns, allowing the cavities ...

Standard design, stable function, common pump. ... Duplex SS stainless steel with hardening treatment: Excellent: Excellent: 1000~40000:
A progressing cavity (PC) pump employs a positive displacement principle. A typical PC features a suction inlet which feeds into an elongated casing. Within this casing sits a helical 'worm' rotor and stator assembly. The rotor helix is shaped off-set to the stator creating cavity spaces in the assembly which are formed by temporary seals as ...
Progressive cavity pump stators will be destroyed if run dry, even for a brief period. Sharply lower maintenance and repair cost. Require approx 1/3 their physical space. In addition, progressive cavity pumps need additional space for removing the rotor and stator. LobePro rotary pump lobes, seals and wearplates can be replaced in place without ...

The Progressing Cavity Pump is a helical gear pump consisting of an internal gear with a double thread (stator) and an external gear with a single thread (rotor). The meshing of the two gears forms a cavity, which progresses along the axis of the assembly as the rotor is rotated. The cross section of the stator is two semi-
NEMO ® 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 progressing cavity pump is a positive displacement pump with a helical rotor spinning inside a fixed stator, forming cavities that lift the fluid, including viscous fluids and fluids with high sand cut or a large percentage of free gas.
