Positive Displacement Pumps Market Insights
Positive Displacement Pumps – Positive displacement pumps dominate in handling viscous, abrasive, and multiphase fluids.
Positive displacement (PD) pumps are a type of pump that moves a fixed amount of fluid with each cycle or rotation. Unlike centrifugal pumps, which rely on velocity and pressure to move fluid, PD pumps displace fluid directly, making them ideal for precise flow control and handling viscous, shear-sensitive, or abrasive fluids.
Key Features of Positive Displacement Pumps
Fixed Volume per Cycle: Delivers a consistent, predictable flow regardless of system pressure.
Versatility: Handles viscous, abrasive, corrosive, and shear-sensitive fluids efficiently.
High Efficiency at Low Flow Rates: Maintains performance even at high pressure or low speed.
Pressure Capabilities: Can operate effectively in high-pressure systems without significant efficiency loss.
Low Pulsation Options: Advanced designs reduce pulsation, vibration, and noise.
