Progressive Cavity Pumps: Technology, Benefits & Apps

A progressive cavity pump is a kind of positive displacement pump. It moves fluid through small, fixed-shape cavities as the rotor turns. This design provides a steady flow rate based on the rotor's speed. It also causes little shearing of the fluid being pumped.

• High Efficiency and Reliability:PC pumps are known for their efficiency and consistent performance, which reduces the risk of equipment failure and production disruptions.
• Low Shear: The progressive cavity pump gently handles shear-sensitive materials like food products or adhesives.
• Smooth Flow: Delivers a virtually pulse-free flow, perfect for metering and dosing applications.
• Versatility: Capable of pumping a variety of fluids, from water to non-flowing products.
• Simplicity of Operation: Their design is straightforward, making them easy to install, operate, and maintain, saving time and money while ensuring reliable performance.
• Ability to Handle Challenging Fluids: PC pumps can effectively move a wide range of fluids, including those with high viscosity or containing solids, making them suitable for various applications.
• No Valves or Reciprocating Parts: This means there is nothing to clog, gas lock, or wear out, enhancing the pump’s durability.
• Good Resistance to Abrasion:This makes the progressive cavity pump suitable for pumping fluids that contain abrasive particles.

• High Suction Lift Capabilities:self-priming characteristics make it possible to handle suction lifts up to 9m (29.5 ft.)
• Economical: SEEPEX guarantees state-of-the-art products, the highest quality of all components, optimised design and manufacturing capabilities – resulting in long pump life and low operating costs.
• Service-friendly: Our maintenance solutions including Smart Conveying Technology (SCT) and Drive Joint Access (DJA) reflect our guiding principle to provide the ultimate service-friendly design.

Understanding the working principle behind the progressive cavity pump is crucial for industries that rely on their efficient and reliable fluid handling capabilities. This type of pump, known for its versatility and performance, operates on a simple yet ingenious rotor-stator design.

The Rotor-Stator Interaction

At the core of a progressive cavity pump is the rotor-stator interaction.The rotor is a carefully made metal part with a single helix. It fits tightly inside the stator’s double-helix space. The stator is usually made from a strong elastomer. It shapes itself to the rotor, forming cavities that keep their size and shape during pumping.

Fluid Movement and Sealed Cavities

As the rotor turns, it forms tightly sealed cavities that trap the fluid. These cavities then progress from the pump’s inlet to its discharge port, ensuring a consistent and controlled flow. This unique mechanism allows the progressive cavity pump to handle a wide range of fluid viscosities and compositions, from water to thick sludges, without altering the fluid’s integrity.

Low Shear and Pulsation

One of the standout features of progressive cavity pumps is their low shear operation. The gentle movement of the rotor minimises the shearing forces applied to the fluid, making these pumps ideal for shear-sensitive materials like food products, e.g. yoghurt, or delicate chemical mixtures.

Consistent Flow and Efficiency

Regardless of the fluid’s viscosity, progressive cavity pumps deliver a constant flow rate. This consistent performance, coupled with the pump’s high volumetric efficiency, makes it a preferred choice for applications requiring precise fluid handling and metering.

When choosing a progressive cavity pump, consider factors like fluid type, flow rate, pressure needs, and installation space. As a manufacturer, we make sure our PC pumps meet high industry standards. This ensures reliable and efficient performance for all uses.
