Tolerance between the rotor and the volute in the 4″ EDDY Pump easily allows the passage of a man’s arm (*see picture below). Compared with the tolerance in a centrifugal pump, the EDDY Pump easily wins. Pump Range spans 1-inch through 12-inch EDDY Pump line, the tolerance ranges from 1-12 inches.
This translates to a significant amount of solids and debris pass through, without clogging the pump. To learn more about the technology behind our pumps continue reading Here.
Dredging projects are subject to various established regulations and permitting requirements. Our team is well-versed in the regulatory framework governing dredging operations and can assist project owners in obtaining the necessary permits and approvals. We ensure that our clients comply with all relevant laws and regulations, minimizing the risk of problems, delays, fines, or legal repercussions. By staying informed about the latest regulatory changes, we help our clients navigate the permitting process smoothly and efficiently.
The core of this design is the patented EDDY Pump technology, which does differ to both that of a regular self priming centrifugal pump and a positive displacement pump. The design redefines the pumping industry by being the only pump that utilizes the principles of a tornado to create a synchronized eddy current from initial priming. This pump is not a self priming centrifugal pump, positive displacement, or vortex pump but instead the most highly efficient high solids and high specific gravity pump on the market.
An ideal system for pumping the most viscous and heavy suspended solids without clogging or having significant downtime due to a run dry situation. Lower downtime and maintenance issues versus conventional positive displacement or self priming centrifugal pumps will save your project money. Pump size options range from the 2-inch slurry pump to a 12-inch option. Our system handles pumping distances over feet to the tank and production rates up to GPM from the suction and discharge sides.

A self-priming slurry pump is designed to handle slurries (mixtures of solids and liquids) and prime itself without external assistance, eeven during intermittent operations. This means it can evacuate all the air from the suction line and begin pumping without the need for a manual priming cycle. Even when pumping water or other liquids, the ability to evacuate air bubbles to keep air pockets from creating an air bound situation is very key.
Self-priming slurry pumps utilize a combination of centrifugal force and air/water separation to achieve self-priming. When the pump is started, the impeller rotates, creating a centrifugal force at the suction side that pushes the slurry toward the discharge port. Simultaneously, air present in the suction line is expelled through the discharge port, allowing the pump to prime itself.
The main advantages of self-priming slurry pumps include:
Self-priming slurry pumps are ideal for a wide range of applications, including:
Dredging: Removing sediment, sand, and debris from bodies of water or a reservoir.
Mining: Transferring abrasive slurries containing minerals and ores.
Construction: Pumping slurry mixtures during tunnelling, excavation, and foundation work.
Industrial: Handling wastewater, sludge, and other challenging fluids in various industry process lines.
Yes, self-priming slurry pumps are specifically designed to handle abrasive materials such as sand, gravel, and rocks, something that differentiates it from a regular self priming centrifugal pump. Their robust construction, including wear-resistant materials and heavy-duty components throughout the pump body, allows them to withstand the erosive effects of abrasive slurries.
Selecting the appropriate self-priming slurry pump involves considering factors such as the type and characteristics of the slurry, required flow rate, discharge pressure, and operating conditions. Consulting with a pump expert or utilizing sizing tools provided by manufacturers can help determine the most suitable pump for your specific application.
Routine maintenance for self-priming slurry pumps typically includes inspecting and replacing worn parts such as impellers, liners, and seals as needed. It’s also essential to monitor pump performance regularly, check for liquid leaks under high pressure, and lubricate moving parts according to the manufacturer’s recommendations. Regular maintenance helps ensure optimal pump performance and extends its service life.

Self-priming slurry pumps can be designed and operated in an environmentally friendly manner by employing features such as efficient hydraulic designs, energy-saving motors, and using environmentally friendly lubricants. Additionally, proper maintenance and responsible disposal of any hazardous materials used in the pumping process contribute to minimizing environmental impact.
Yes, many manufacturers offer customization options for self-priming slurry pumps to meet the unique requirements of different applications. This may include modifications to construction materials, pump configuration, and accessories such as control panels, instrumentation, and specialized coatings for enhanced wear resistance. Discussing your specific needs with a pump supplier can help you tailor a solution to fit your application.
Priming pumps are used to remove air or gas from the suction line of a pump, allowing it to effectively draw in and pump fluid. This process is essential for ensuring efficient operation, particularly in situations where the pump is located above the level of the fluid being pumped.
A self-priming pump utilizes a unique design that allows it to automatically prime itself without needing external priming assistance. This is achieved through a combination of air-water separation and centrifugal force, which expels air from the suction line and creates a vacuum to draw in fluid.
Self-priming pumps offer several advantages, including:
Yes, self-priming pumps are a type of centrifugal pump. They utilize centrifugal force generated by an impeller to impart kinetic energy to the fluid, creating pressure and facilitating pumping action.
Self-priming pumps can be classified as centrifugal pumps. However, they feature specialized designs and components that enable them to prime themselves automatically.
Self-priming pumps are used in various applications across industries, including:
Wastewater treatment
Irrigation and agriculture
Marine and offshore
Construction and dewatering
Industrial processes
Mining and mineral processing
The main components of a self-priming pump typically include:
Impeller: Rotating component that imparts kinetic energy to the fluid.
Casing: Enclosure that houses the impeller and volute, directing fluid flow.
Volute: Shaped chamber that converts kinetic energy into pressure.
Suction and discharge ports: Inlet and outlet connections for fluid entry and exit.
Priming chamber: Section of the pump where air-water separation occurs during priming.
Check valve: Prevents backflow of fluid into the suction line.
There are several types of pumps priming methods, including:
Manual priming: Using external means such as a hand pump or vacuum removes air from the suction line.
Automatic priming: Utilizing built-in mechanisms within the pump to expel air and prime itself automatically.
Continuous priming: Maintaining a primed state during operation, ensuring uninterrupted pumping.
No, not all pumps require priming. Some pumps, such as submersible or positive displacement pumps, operate below the fluid level and do not require priming. However, priming is necessary to initiate pumping action effectively for pumps located above the fluid level or in situations where air may enter the suction line.
