Dredge Manufacturer EDDY Pump – Benefits and Technology Overview

EDDY Pump is a USA Dredge Manufacturer, focused on Slurry Pumps and Dredge Equipment. Let’s review the technology and patented design.

Traditional Dredge & Slurry Pumps

Challenge: Traditional Dredge & Slurry Pumps

In harsh conditions with sand, sludge, rocks, slurry, other traditional dredge pumps:

  • Routinely get clogged
  • Wear down quicker
  • Fail more often
  • Downtime for maintenance hurts your bottom line

Solution: Non-Clog EDDY Pumps

  • Open Rotor Design
  • Non-Clog, High Viscosity, High Specific Gravity, High Abrasives, Low pH Pumping Design
  • 40-70% Solids Pumping by Volume
  • Ability to pump objects of up to 11-inches in diameter
  • State-of-the-Art Research and Development Facilities
  • 100% American Made
  • Low Total Ownership Cost (See PDF)

Non-Clogging Slurry Pump Design

The EDDY Pump’s open rotor design with high tolerances allow anything that will go into the intake to be passed through the discharge without issues.

As you can see in the 4″ EDDY Pump shown above, the tolerance between the rotor and the volute easily allows the passage of a man’s arm , while the tolerance in a centrifugal pump is significantly less.   In a 1-inch to 12-inch EDDY Pump the tolerance ranges from 1-12 inches.

This translates to a significant amount of solids and debris that passes through without clogging the pump.

Non-Clogging & Lower Maintenance = Increased Profits

High Viscosity Red Mud Moved Like Water!

Amazing video demonstrates the EDDY Pump effect in action.

High Viscosity

The EDDY Pump rotor acts as a mixer on thixotropic materials and provides a shear thinning effect. The EDDY Pump’s ability to pump concentrated solids is perfect for moving viscous materials with less than 5% free liquid; an impossible task for centrifugal pumps.

High Specific Gravity

The EDDY Pump is excellent at moving heavy materials through long pipelines. The EDDY Pump creates a turbulent flow that helps keep the heavy materials in suspension and moving down the pipeline.

Total Life Cycle/Ownership Cost

The EDDY Pump design and superior performance allows for a significantly decreased Ownership Cost over centrifugal and PD Pumps.

Please see link below to see a the Total Life Cycle and Ownership Cost Study conducted by one of the largest US Navy Ship Building Companies in the World, showing that 25 EDDY Pumps would save the US Military over $17,000,000 over 4 years in operation.

Lowest Cost of Ownership

High Production Capability

Up to 300% higher than a similar sized centrifugal pump in pumping non-organic material.

High Concentration Capability

Less fluid required to pump a given amount of material. Up to 80% solids by volume in-situ.

High Abrasive/Corrosive Material Pump Ability

EDDY Pump does not require critical tolerances between the rotor and the volute, making the EDDY Pump the perfect solution for abrasive and corrosive applications that often cause significant issues for other pumps.   The EDDY Pump will outperform any pump in moving the most  abrasive fluids with minimal wear and no maintenance.  These include lime slurries, borax, drilling muds, and ash.

Economic Advantages

Pump less water, more solids and you have huge cost savings. To move the same amount of material the EDDY Pump will be smaller in size, lighter in weight, use less power and cost less than conventional equipment.   Further, there is no critical setup, eliminating the expense of balancing and alignment that other pumps incur.

Varying Rotor size will change the Flowrate and PSI

The EDDY Pump can be customized to a specific flow rate and Head requirement for an application simply by changing the rotor size. Each pump model has multiple rotor options available. This allows for the most efficient combination of pump and motor size for the job.

The tough simplicity of the EDDY Pump along with its proven eddy pumping effect translate into extended run times, no clogging, and higher production compared to conventional pumping technologies. See 3rd party Cost Analysis for US Navy Pumps HERE

Serious Research & Development

Rapid Prototyping and Research Done In-House.

  1. New Idea Meeting
  2. CFD Modeling using ANSYS (Really expensive software for deep insights and modeling)
  3. 3D Print a Test Unit
  4. All within 48 Hours
  5. USA Based Dredge Manufacturer means faster response time

EDDY Pump has dedicated engineers for pump modeling and analysis. We can go from concept to modeling and then pump out a 3D printed test unit in 48 hours. Heavy investments have been made in hardware and software to assist the research team.

Our comprehensive knowledge of fluid dynamics as it relates to pumps combined with our experience in structural engineering allows us to provide completely optimized pumps and dredging equipment with adjoining pipelines and hoses. Our research and development utilizes computational fluid dynamics (CFD) software to accurately calculate flow uniformity across the system.

At EDDY Pump, we are constantly striving to improve and innovate new technologies to incorporate into our pump and dredging equipment.

We are one of the few companies who manufactures both our pumps and dredging equipment to ensure optimal support.

Mechanical Seal Support System

This Plan 53A dual-facing mechanical seal is completely self-contained and can be constructed using tungsten carbide and silicon carbide seal faces. The benefit of this seal system is that it doesn’t need any external flushing water. The self-contained seal support system consists of a pressurized tank filled with a water-glycol mixture which recirculates over the seal faces to protect the seal during pump operation.

EDDY Pump Components

The EDDY Pump consists of an

(1) energy generating rotor  attached to the end of a
(2) drive shaft and placed within a
(3) volute. . As the rotor begins to spin, it sets into motion the ambient fluid present within the volute and
(4) adjoining intake chamber. At normal operating speed, this spinning fluid is forced down, into the hollow center of the intake chamber where it creates a high speed, swirling synchronized column of fluid
(5) which agitates the material
(6) to be pumped (sludge, sand, clay etc.) This swirling column of fluid creates a peripheral
(7) “eddy” effect which causes the agitated material to travel by reverse flow, up along the sides of the intake chamber, into the volute. Here the material, under pressure from below, is forced into the
(8) discharge pipe.
