The Challenge: Inefficiency in Handling Viscous Fluids
Currently, the pneumatic diaphragm pump is being used to transfer the material. However, its performance is compromised due to the thickness and high friction of the liquid. These challenges can lead to pump failure, inconsistent flow rates, and inefficient material transfer.
Why Standard Pumps Struggle with High Viscosity
- Flow Control Issues: Diaphragm pumps are not designed to maintain a consistent flow rate for highly viscous fluids.
- Increased Wear & Tear: The friction within the liquid can accelerate pump component deterioration.
- Product Retention: Some pump designs fail to completely evacuate the liquid from the system, leading to waste and contamination risks.
The Solution: Eccentric Disc Pumps for Reliable Flow Control
Upgrading to an eccentric disc pump provides a more efficient, reliable, and durable alternative. Unlike centrifugal pumps or pneumatic diaphragm pumps, eccentric disc pumps are specifically designed to handle high-viscosity liquids with precision.
Key Advantages of Eccentric Disc Pumps
- Consistent Flow Rate – Regardless of viscosity fluctuations, the flow remains stable.
- Self-Priming & Dry Run Capability – The pump can completely evacuate the pipeline, minimizing waste.
- Superior Product Recovery – Reduces residual material left in the system, enhancing efficiency and cost savings.
- Gentle Handling – Maintains fluid integrity by minimizing shear stress, making it ideal for sensitive materials like sugar syrup.
Understanding Viscosity: Why It’s Critical for Pump Selection
Viscosity is often described as a liquid’s thickness, but this definition is oversimplified. Water has low viscosity, while honey is highly viscous, but the real measure of viscosity is the internal friction between molecules.
- At the Molecular Level: Viscosity represents the resistance to flow caused by interactions between liquid molecules.
- Energy Demand: Just as friction affects the movement of solids, viscosity determines the energy required to move a fluid through a pipeline.
How Viscosity Affects Pump Performance
When selecting a pump, it’s essential to consider how viscosity impacts flow behavior. Higher viscosity increases:
- Resistance to Movement – Requiring more power to maintain flow.
- Shear Sensitivity – Some liquids, such as syrups and oils, degrade when subjected to excessive shear forces.
- Pump Efficiency – Centrifugal pumps lose effectiveness as viscosity increases, leading to uneven flow rates and excessive wear.
Critical Viscosity Considerations When Choosing a Pump
- Flow Resistance – High-viscosity fluids require positive displacement pumps, like eccentric disc pumps, for consistent performance.
- Material Adherence – Fluids like engine oil or sugar syrup can stick to pump components, reducing efficiency in turbine or centrifugal pumps.
- Temperature Sensitivity – Some liquids become more viscous in lower temperatures, requiring a pump that adapts to fluid consistency changes.
Why Eccentric Disc Pumps Are the Best Choice for High-Viscosity Fluids
Unlike traditional pumps, eccentric disc pumps maintain efficiency regardless of viscosity fluctuations. This makes them ideal for industries dealing with thick, sticky, and shear-sensitive liquids.
