Market Insight: Choosing the Right Progressive Cavity Pump – Key Features and Brand Landscape

 Market Insight: Choosing the Right Progressive Cavity Pump – Key Features and Brand Landscape

Progressive cavity pumps—commonly referred to as single screw pumps—have become a staple in industries requiring the transfer of high-viscosity or solid-laden fluids, such as wastewater treatment, oil extraction, food processing, and chemical manufacturing. Their ability to deliver low-pulsation, stable, and shear-sensitive flow makes them ideal for continuous and precise fluid handling.

Why Progressive Cavity Pumps?

Unlike centrifugal pumps that rely on impellers, progressive cavity pumps use a rotor-stator structure to form sealed cavities that transfer fluid evenly. Core advantages include:

✅ High tolerance for viscous and abrasive fluids

✅ Gentle conveying action, ideal for fragile or shear-sensitive media

✅ Capable of handling multiphase flow (liquid + gas + solids)

✅ Self-priming and reversible flow capabilities

✅ Minimal pulsation, suitable for metering applications

Key Considerations When Selecting a Screw Pump

Material Compatibility: Ensure proper rotor/stator combinations based on fluid properties (e.g., stainless steel, rubber, FKM)

Maintenance: Choose pumps with easy disassembly and spare parts availability

Seal Configuration: For abrasive or corrosive fluids, mechanical seals or packing glands should be considered

Flow & Pressure Requirements: Pump performance must align with system demands

Customization: For large projects, suppliers that offer tailored solutions will have an edge
