NEMO® Progressing Cavity Pumps: Working Principle

Progressing cavity pumps are a type of rotary positive displacement pump. The main conveying components of this pump are a rotating Rotorrotor,Rotors,rotorsrotor and a fixed stator that create continuous movement of fluids through the pump cavities. The interference in these pump elements ensures excellent priming and pressure-holding ability resulting in a smooth flow from suction to discharge and thereafter. 

The pump's constant and smooth flow of the fluid from one cavity to the other using the rotary motion ensures smooth flow of the pumped medium with minimal pulsation. This also makes the pump ideal for handling fluids with solids, which can be abrasive or shear sensitive to be pumped without causing damage. The NEMO® pump is a self-priming device and features a valveless design, ensuring low-pulsation flow for highly viscous and abrasive media.

NEMO® Progressive Cavity Pump Working Principle 

The NEMO® Pump is offered in four different variants of pumping element designs known as geometries of rotor and stator shapes. The elements are selected according to the size of the pump, for the application and hydraulic requirements. The elastomeric parts like stators, and seals are manufactured in-house with the high level of know-how in elastomer compounding technology and using the latest production methods and product standards. 

The flow rate of the pump is directly proportional to the diameter of the pump cavities or conveying spaces. Its flexible design allows easy flow rate and pressure changes by switching rotor and stator types. The pressure handling capability is improved by adding lengths of rotor/stator elements to reach up to 72 bar in Industrial applications and 240 bar in special applications. 

The main features include high suction capability, convey liquids at variable flow in constant pressure, the ability to reverse flow, and versatile installation options with the least vibrations. These features for handling fluids of viscosities less than 1 cP to 1 Million cP and at temperatures from -20°C to +160°C. These features make it an optimal solution for handling complex fluids.

NEMO® Pump Capabilities and Range

The features and flexible options of NEMO® Progressing Cavity Pumps are 

  • Wide Flow Range: These NEMO® pumps can handle flow rates from 1 LPH up to 1000m3/hr, efficiently managing conveying of very low to large volumes of complex fluids.
  • Excellent Self Priming: The NEMO Pump is an excellent self-priming pump being able to draw liquids from a 9 meters water column. They are hence used for suction with negative lift or fluids from a vacuum tank.
  • High Differential Pressures: The pump can convey fluids against pressures from 1 bar up to 240 bar, making them ideal for a very wide range and high-pressure applications.
  • Wide Viscosity Range: NEMO® pumps can convey viscous liquids from 1cP to 3 million cP, with their ability to handle various fluid consistencies.
  • Good Solids Handling: The NEMO Pump is excellent in handling slurries with abrasive solids with minimal wear offering the best lifetime for the pumping elements.  They can handle upto 70% solids in liquids.
  • Handling Complex Liquids: Capable of pumping high-viscous, abrasive liquids containing solid particles and corrosive and shear-sensitive substances.
