Pumping high-viscosity fluids—such as heavy oil, sauce, sludge, or paste—often poses a major challenge. Conventional centrifugal pumps tend to lose efficiency and can even break down when faced with extreme viscosity. This is where the Sydex K-Series screw pump plays a vital role. Specifically designed to handle these challenges, the Sydex K-Series offers a reliable and efficient solution that is unmatched by other types of pumps.
Understanding the Challenges of High Viscosity
Viscosity is a measure of a fluid’s resistance to flow. The higher the viscosity, the thicker and stickier the liquid. In centrifugal pumps, which rely on centrifugal force to move fluids, high viscosity can cause:
- Decreased Capacity: Fluid flow is drastically reduced due to high internal friction.
- Overheating: Energy that should be used for pumping is converted into heat due to friction, which can damage seals and internal components.
- Inefficient Energy Consumption: The pump works harder without producing commensurate output.
Solutions from Positive Displacement Mechanisms
Different from centrifugal pumps, the Sydex K-Series operates based on the principle of positive displacement. Its mechanism does not depend on speed, but rather on the ability of its rotor to trap and forcefully push fluid.
Here’s how the Sydex K-Series works to overcome high viscosity:
- Trapping Fluid: The rotating screw rotor creates a closed space between the screw and the stator. Viscous fluids entering the pump are immediately trapped in this space.
- Constant Pushing: With continuous rotation, the trapped fluid is pushed forward axially. This process ensures constant flow, regardless of how viscous the fluid is.
- High Efficiency: Since there is no internal slip as in centrifugal pumps, the Sydex K-Series pump maintains its efficiency even with the most viscous fluids. This means lower energy consumption and more consistent performance.

Additional Advantages for Critical Applications
In addition to its effectiveness in handling high viscosity, the Sydex K-Series also offers other important advantages:
- Pulsation-Free Flow: Provides a very stable flow, ideal for processes that are sensitive to fluctuations, such as in the food or pharmaceutical industries.
- Exceptional Suction Capability: Capable of sucking liquids from low heights (self-priming) without the need for a booster pump.
With all these advantages, the Sydex K-Series pump is not just an alternative, but the best choice for ensuring smooth and efficient operations in industries dealing with viscous liquids.
