Techniques

Chapter 1: Techniques - Progressing Cavity Pumps (PCPs) in Action

This chapter dives into the core technology behind Merlin pumps - the Progressing Cavity Pump (PCP).

The Power of Positive Displacement:

PCPs stand apart from traditional centrifugal pumps with their unique positive displacement mechanism. This means they create a sealed pocket within the pump chamber, trapping and moving fluid with each rotation of the rotor. This results in:

• High Efficiency: Less energy is lost due to fluid slippage, leading to significant cost savings in the long run.
• Gentle Handling: The smooth, continuous flow of PCPs minimizes shear stress on delicate materials, preserving their integrity.
• Versatility: Capable of handling a vast range of fluids, from viscous slurries to abrasive solids, making them adaptable for diverse applications.

Merlin's Design Excellence:

The Merlin PCP features a robust design, specifically tailored for demanding environments:

• Rotor: Precisely machined helical screw with a tailored profile ensuring optimal engagement with the stator.
• Stator: A flexible rubber-like component with a custom cavity for precise fluid displacement.
• Materials: Corrosion-resistant materials are employed to combat the harsh environments often encountered in environmental and water treatment.
