Advanced Rotor Design
Patented EDDY Boundary Layer Rotor Technology
The revolutionary EDDY Boundary Layer Rotor is at the heart of our new HHHV Pump. This patented component creates a boundary layer effect, significantly reducing the disturbance of pumped materials. The EDDY Boundary Layer Rotor enables the pump to handle liquids with viscosities of up to 75,000 centipoise, setting a new standard in the industry.
Validated through computational fluid dynamics (CFD) analysis and rheology testing, the rotor maintains flow rate as viscosity rises — where centrifugal pump performance collapses and positive displacement pumps demand ever-higher torque.
Mining Material Handling
The versatility of the EDDY HHHV Pump makes it ideal for a wide range of industries and applications.
Applications of the EDDY HHHV Pump
Oil & Gas
Efficiently pump high-viscosity crude oil and drilling muds with minimal disruption for heavy oil transfer, bitumen and asphalt transfer, and refinery applications.
Mining
Handle slurries, tailings, and other viscous materials commonly found in mining operations, including viscous slurry pump duty for thickened tailings and paste.
Chemical Processing
Transfer high-viscosity chemicals and compounds with ease and precision, including polymers, resins and epoxy, adhesives, and paint manufacturing applications.
Food & Beverage
Pump thick food products such as syrups, sauces, and pastes without altering their consistency, with low-shear, food-grade pumping for molasses and chocolate transfer.
Municipal
Manage sludge, wastewater, and other high-viscosity liquids in municipal treatment facilities, including wastewater sludge transfer and digester sludge handling.
Centrifugal vs. High Viscosity Pump: Which Do You Need?
Can centrifugal pumps handle viscous fluids? Only to a point. Above roughly a few hundred centipoise, centrifugal pump efficiency falls off sharply — head drops, power demand climbs, and the pump runs off its curve. That is why thick fluids are traditionally moved with positive displacement pumps: gear pumps, screw pumps, rotary lobe pumps, and progressive cavity pumps.
Positive displacement designs bring their own trade-offs: tight internal tolerances that wear in abrasive service, elastomer stators that fail with hot or chemically aggressive fluids, and shear that can damage sensitive products. The EDDY HHHV takes a third path — the boundary layer rotor delivers positive-displacement-class viscosity capability with open clearances, so it tolerates solids and abrasives that destroy gear and screw pumps.
Energy Efficiency Boost
When choosing the EDDY HHHV Pump, you invest in cutting-edge technology and unparalleled performance.
Benefits of Choosing EDDY Pump

Frequently Asked Questions
What is a high viscosity pump?
A high viscosity pump is an industrial pump designed to move thick fluids — oils, sludge, resins, pastes, and viscous slurry — that ordinary centrifugal pumps cannot handle efficiently. They are typically positive displacement designs; the EDDY HHHV achieves the same capability with a patented non-clog boundary layer rotor.
What pump handles high viscosity fluids best?
It depends on the fluid. Gear and screw pumps suit clean viscous liquids; progressive cavity pumps suit sludge. For viscous fluids that also carry solids or abrasives — tailings, drilling mud, wastewater sludge — the EDDY HHHV handles up to 75,000 cP without tight tolerances that wear out.
What are the main high viscosity pump types?
Common high viscosity pump types are gear pumps, twin screw pumps, rotary lobe pumps, progressive cavity pumps, and peristaltic pumps — all positive displacement designs — plus the EDDY boundary layer rotor pump, which combines high-viscosity capability with solids tolerance.
What is the maximum viscosity the EDDY HHHV can pump?
The EDDY HHHV pumps fluids with viscosities up to 75,000 centipoise (cP), while delivering heads over 500 ft TDH (215 psi) — enough for long pipeline runs and significant lift.
Can a centrifugal pump handle viscous fluids?
Generally no. Centrifugal pump performance degrades quickly as viscosity rises — flow and head drop while power consumption climbs. Above a few hundred centipoise, a positive displacement or EDDY-type pump is the efficient choice.
Does pumping damage shear-sensitive products?
With the wrong pump, yes. The EDDY boundary layer effect minimizes liquid disturbance, making the HHHV suitable for low shear pumping of food products, polymers, and other shear-sensitive materials without altering their consistency.
How do I size a pump for a high viscosity application?
Pump sizing for thick fluids requires a viscosity correction: flow, head, and power must be adjusted from water performance. Send us your fluid, viscosity, temperature, and duty point, and EDDY engineers will produce a corrected custom pump curve.
What industries use high viscosity pumps?
Oil and gas, refining, petrochemical, chemical processing, mining, wastewater treatment, food processing, asphalt and bitumen production, paint and adhesive manufacturing, and polymer processing all rely on high viscosity pumps for thick fluid transfer.
