Open Hopper Cavity Pump Introduction

Open Hopper Cavity Pump is a type of positive displacement pump that is designed to handle viscous and shear-sensitive materials. It has an open hopper or feeding area which allows for easy loading and unloading of the material being pumped. The pump’s unique design features a rotor that rotates inside a stator, creating a cavity that changes in volume as the rotor turns. This creates a gentle pumping action that is ideal for transferring delicate materials without causing damage or degradation.

The Open Hopper Cavity Pump is suitable for a wide range of applications including food processing, pharmaceuticals, chemical processing, and wastewater treatment. It can handle fluids with high solid content or high viscosity and offers excellent suction capability, even with low NPSH (Net Positive Suction Head) available.

In terms of maintenance, the pump is easy to clean and disassemble, with no dead zones or crevices where material can accumulate. It also has a hygienic design with smooth surfaces that minimize the risk of contamination.

Open Hopper Cavity Pump Introduction

  • Chemical transfer: The pumps are ideal for handling aggressive chemicals, acids, and alkalis without damaging the pump or affecting the fluid quality.
  • Food processing: The gentle pumping action of open hopper cavity pumps makes them suitable for handling viscous and chunky food products such as jams, sauces, and purees with minimal damage to the product.
  • Wastewater treatment: The pumps can handle sludge, grit, and other solids present in wastewater, making them suitable for use in wastewater treatment plants.
  • Oil and gas: Open hopper cavity pumps are commonly used in the oil and gas industry for fracking, drilling fluids, and well-servicing operations.
  • Mining: The pumps can handle abrasive slurries containing solids like mud, sand, and gravel, making them an essential tool for mining operations.

  • Gentle pumping action: The pump’s design ensures gentle pumping action, which minimizes product damage and maintains the fluid’s integrity.
  • Self-priming: The open hopper design allows the pump to self-prime, eliminating the need for additional priming equipment.
  • Low shear: The low shear pumping action makes the pumps ideal for handling shear-sensitive fluids.
  • High suction lift: The pumps can handle fluids with high viscosity and still maintain a high suction lift.

Open Hopper Cavity Pump Introduction Summary

open hopper cavity pumps are versatile, reliable, and suitable for various industrial applications. Their unique design and features make them an essential tool for handling viscous and abrasive materials.
