Diaphragm Pump vs The EDDY Pump

Diaphragm pumps are either air or electric operated. Air diaphragm pump units are more common. Diaphragm pumps are positive displacement (as opposed to a centrifugal pump n), self-priming pumps and are available in a variety of materials. Usually, they come with inlet and discharge port sizes ranging from 1/4-inch to 4-inch. They are considered portable pumps because they are lighter than most other industrial pumps of equivalent port sizes. The air chamber in air-operated diaphragm pumps directs compressed air to the chamber, driving the diaphragm and minimizing mechanical stress.

Eddy currents are reinforced by the presence of solid particles which increase the inertial forces in the fluid. The formation of eddy depends on the suspended solid particles that cause suction. Unlike vortex pumps, the rotor directly drives the fluid through the pump with no slip. The EDDY Pump uses the movement of particles and the wake induced from these solid particles to generate eddy Current and induce suction.

The EDDY Pump is designed to excel in applications that require pumping high viscosity fluids or fluids with high solids content. This pump features a large flow through liquid path that is well suited for high viscosity solid laden fluids. The EDDY Pump can pass solids that are almost the diameter of the pump discharge port. Cavitation can impact components such as diaphragms and valves, but it can also affect the pump body, emphasizing the importance of understanding this phenomenon to mitigate operational costs.

• Non-Clog Pump Design – The EDDY Pump is designed with a recessed rotor which is essential to the large flow-through design of the pump. This large flow-through design easily passes solids that can fit through the inlet port of the pump. As an example, a 10-inch EDDY Pump allows the passage of solid objects up to 9 inches in diameter. Unlike air-operated double diaphragm pumps, which rely on flexible diaphragms and air valve systems, the EDDY Pump’s design focuses on minimizing clogs through its unique rotor technology.
• High Solids Handling – The rotor technology effectively agitates and pumps material of up to 70% solids by volume using a geometrically shaped energy-generating rotor. Double diaphragm pumps also excel in handling high solids, utilizing their diaphragm and air valve systems to efficiently manage a variety of fluid applications.
• No Critical Tolerances – The spacing in the flow path between the rotor and the volute are sized to pass extremely large solids. Most other types of pumps are designed so that they require a tighter tolerance in this area of the pump to operate properly, this includes centrifugal pumps.
• High Viscosity and High Abrasives Handling – Ultra recessed rotor creates an eddy current that keeps abrasive material away from critical pump components.
• Low maintenance and minimum downtime.
• Low Cost of Ownership – The low maintenance, non-clogging pump technology allows a much quicker return on investment over other pumps, making it the lowest life-cycle cost pump on the market today.
