Chopper Transfer Progressive Cavity Pump

Home » About Screw Pump » Chopper Transfer Progressive Cavity Pump

Introduction

The chopper transfer progressive cavity pump is a unique and innovative solution in the world of fluid transfer. This type of pump is designed to handle a variety of challenging materials, making it an essential tool in various industries. Its ability to manage thick, viscous fluids with solid content sets it apart from conventional pumping systems.

How It Works

The chopper transfer progressive cavity pump operates on a simple yet effective principle. It utilizes a helical rotor and a stator to create a series of cavities that transport the fluid. The inclusion of a chopping mechanism allows the pump to break down solids before transferring them, ensuring smooth operation and preventing blockages.

Key Components

  • Helical Rotor: This component rotates within the stator, creating compartments that move the fluid forward.
  • Stator: A stationary part that surrounds the rotor, providing a seal and ensuring efficient fluid transfer.
  • Chopper Mechanism: Located at the inlet, this component cuts large solids into smaller pieces, facilitating easier pumping.

Chopper pumps are used extensively in heavy duty solids-laden water applications including municipal waste water, industrial sewage, food processing, agricultural byproduct, and raw untreated drainage run-off from metal, paper and chemical industries.

A progressing cavity pump is a positive displacement pump employing a helical ‘worm’ rotor and stator assembly to create temporary chambers to draw fluid into, which ‘progress’ through the pump resulting in the fluid being expelled through the discharge port.

Due to their positive displacement, they can be sensitive to dry running if not sufficiently lubricated, leading to increased wear. Another factor is the limited pumping speed compared to other pump types such as multi screw pumps, which can make them difficult to adapt to high flow rate applications.
