Progressive Cavity Screw Pumps for Highly Viscous and Abrasive Media
The Eagle AESC Series Screw Pump is a positive displacement progressive cavity pump designed for
conveying viscous and abrasive fluids with stable and consistent flow performance. Unlike conventional
centrifugal pumps, screw pumps maintain smooth flow characteristics even while handling thick, fibrous,
and shear-sensitive materials.
These pumps are ideal for applications involving sludge transfer, slurry handling, paste movement, and
industrial fluid dosing systems where controlled material flow is essential. Their progressive cavity
design minimizes pulsation while maintaining accurate volumetric transfer across varying process
conditions.
The ability to handle extremely high viscosities makes these pumps suitable for industries dealing with
challenging fluid handling environments.
Industrial Screw Pumps Engineered for Low Wear and Continuous
Operation
The AESC Series Screw Pumps are engineered with very low internal fluid velocity, significantly
reducing wear, erosion, and operational stress during continuous-duty applications. This low-velocity
design improves pump longevity while ensuring stable material handling in abrasive and high-viscosity
environments.
Speed adjustment capabilities allow operators to maintain controlled and consistent flow rates depending
on the application requirements. The pump design also minimizes operational noise, maintaining sound
levels around 65 dB for quieter industrial operation.
With fewer moving parts and a simplified construction, these pumps offer low maintenance requirements
and easy servicing, reducing operational downtime in industrial process systems.
Working Principle of Progressive Cavity Screw Pumps
Screw pumps operate using a progressive cavity positive displacement mechanism where a rotating
helical rotor moves inside a stationary stator. As the rotor turns, sealed cavities are formed that
continuously move fluid from the suction side to the discharge side of the pump.
This progressive cavity action ensures smooth, non-pulsating flow with minimal shear, making screw
pumps ideal for delicate, viscous, and fibrous materials. The controlled flow movement also prevents
damage to sensitive products while maintaining accurate material transfer.
Because of this operating principle, screw pumps are widely used in applications requiring stable
pressure, controlled flow rates, and reliable handling of difficult industrial media.
High Viscosity Screw Pumps for Sludge, Slurry and Paste Handling
The Eagle AESC Series is specifically designed to handle highly viscous and non-flowing products
with viscosities up to 1,000,000 cP. These pumps efficiently transfer sludge, slurries, honey,
fruit pulp, starch, paste, oils, and industrial waste materials without losing flow consistency.
Their progressive cavity design enables smooth material movement even with abrasive or fibrous
products that are difficult to handle using conventional pumping systems. Adjustable stators and
varying hopper sizes further improve application flexibility based on material characteristics and
process requirements.
This makes screw pumps an ideal solution for industrial operations involving thick, semi-solid, and
challenging media.
Applications of Screw Pumps in Industrial Fluid Handling Systems
Screw pumps are widely used across industries requiring efficient handling of viscous, abrasive, and
fibrous products. In effluent treatment and sewage industries, they are used for sludge transfer and
wastewater handling applications. Mining and civil engineering sectors use screw pumps for slurry
movement and abrasive fluid transfer.
In food processing industries, these pumps handle fruit pulp, honey, starch, dairy products, and
brewing materials with minimal product damage. Chemical and petrochemical industries rely on them
for handling viscous chemicals, resins, and industrial fluids.
Additional applications include paper and cellulose processing, soap and oil refineries, sugar
industries, ceramics manufacturing, paint production, cosmetics processing, pharmaceuticals,
shipbuilding, and railway maintenance systems.
