Aplicaciones de bombas químicas
Con el procesamiento químico, a menudo se emplean productos químicos altamente corrosivos para ayudar en el proceso de fabricación, sin embargo, estos materiales pueden desgastar rápidamente los componentes estándar de la bomba. Descubra cómo la bomba EDDY puede ser la mejor opción para aplicaciones químicas.
Problemas ambientales de las cenizas volantes
1.050 millones de toneladas de carbón se queman en los Estados Unidos cada año dejando desechos dañinos (cenizas volantes) en vertederos. Estos vertederos dañinos de cenizas volantes contienen metales pesados dañinos como mercurio, arsénico, berilio, cadmio, cromo, níquel y selenio.
La ceniza volante tiene una consistencia fina en polvo que es fácilmente transportada por el viento y puede afectar a los vecindarios y personas cercanas. Respirar cenizas volantes con el tiempo puede irritar el sistema respiratorio y las personas con enfermedades pulmonares existentes como enfisema, bronquitis y enfermedad pulmonar obstructiva crónica deben evitar respirar polvo de ceniza volante de carbón.
Dificultades de bombeo
La ceniza volante o ceniza de carbón es un material difícil de bombear debido a su naturaleza abrasiva. Las bombas centrífugas se desgastan rápidamente y pierden sus tolerancias y capacidades de succión. Esto resulta en un tiempo de inactividad significativo y piezas de repuesto costosas.
La ceniza volante se acumula en muchas etapas del proceso de generación de energía y resulta ser muy costosa y lenta de eliminar. Las etapas más problemáticas son lidiar con los estanques de relaves forrados y sin revestimiento, ríos, sumideros y cuencas de concreto.
Los estanques de relaves y los ríos deben limpiarse continuamente para aumentar la capacidad. Encontrar la bomba y el equipo de dragado adecuados a menudo puede ser un proceso complicado. Las bombas centrífugas solo bombearán 10-20% de sólidos en peso. Esto significa que la mayor parte de la descarga es agua y muy pocas cenizas volantes salen de la tubería. Por el contrario, el diseño de la bomba EDDY puede bombear 50-60% de sólidos en peso. Bombea menos agua, más sólidos.
Además, la naturaleza abrasiva de las cenizas volantes destruye el impulsor de la bomba y causa fallas en la bomba, reparaciones costosas y piezas de repuesto. Nuestra bomba tiene un rotor ultra empotrado de alta tolerancia que resiste la naturaleza destructiva de las cenizas volantes.
Los estanques de relaves a menudo están revestidos con plástico para minimizar la filtración de contaminantes. Esto hace que sea más difícil para los equipos convencionales dragar o eliminar mecánicamente el sedimento de cenizas volantes sin dañar el revestimiento. Tenemos una opción de rueda segura para el revestimiento para el accesorio de la excavadora.
Los sumideros son a menudo las áreas más difíciles de manejar en una planta de generación de energía. Las cenizas volantes, los trozos de carbón, las rocas y otros desechos se lavan en sumideros y continuamente deben bombearse. Las bombas centrífugas se obstruyen y se desgastan constantemente debido a las tolerancias entre el impulsor y la voluta.

Chemical Pumping Problems
With chemical processing, highly corrosive chemicals are often employed to aid in the manufacturing process, however, this material quickly wears down standard pump components. Consequently, the pumps used for chemical applications need to withstand materials that are highly corrosive, abrasive, and viscous. This usually means that the top chemical pumps are made out of alloy metals such as nickel, steel or titanium. In addition, chemical pumps often need to be leak-free, preventing the potential to spread of toxic or caustic chemicals into the environment. Chemical pumps have vast applications in many different industries ranging from oil and gas, paper/pulp production, semiconductors, and manufacturing.
Centrifugal pumps are most often used for straight liquid chemical applications, but when thicker materials, such as chemical slurries, sludge, or paint are involved, it can cause a host of issues with pump performance leading to lowered pump efficiency and other costly maintenance problems.
For chemical pump applications, choosing the incorrect metallurgy can cause rapid pump wear which will inevitably lead to critical failures. The first step is a full understanding of the chemical pump application and the material to be pumped, which will guide the overall selection of the pump itself. Caution must be taken to ensure the material used to manufacture the pump is compatible with the target material.
Chemical Manufacturing: The chemical manufacturing industry relies heavily on the use of pumps to reliably transport viscous and corrosive liquids, as well as to keep personnel safe from toxic materials. When dealing with highly viscous and abrasive materials, such as sulphuric acid and lye, it is critical that chemical pumps be constructed of materials designed to withstand the harsh nature of these materials.
Additionally, the corrosive nature of caustic chemicals will quickly eat away the impeller of centrifugal pumps, leading to pump failures, costly repairs, and spare parts. The EDDY Pump has a high tolerance ultra-recessed rotor that withstands the corrosive nature of abrasive chemicals, chemical sludges, and slurries.
Semiconductor Sludge: The manufacturing of semiconductors produces toxic hydrofluoric acid sludge from the wet etching process. In addition, about 30% of industrial waste from semiconductor plants is a fluorine-containing waste. This waste can contain abrasive nanoparticles which can also be highly corrosive to standard pumps.
The EDDY Pump can be run electrically or hydraulically and can be mounted stationary or to a trailer with a self-priming unit. The electric EDDY Pump can also be submersible if needed. In turn, the EDDY Pump will run continuously with significantly less spare parts needed and saving facilities millions in total ownership cost over the life of the pumps.
Paint Sludge Sumps: In paint production and industrial processes that utilize paint, waste chemicals and sludge are collected in large sumps at the bottom of the production facility. Cleaning out paint sumps can be taxing on pump systems due to the natural viscosity of paints and sludge material found at the bottom of the sumps. These sumps need to be periodically cleaned out as they are filled with sludge to prevent excess buildup which could affect production.
Cement Plants: Production of cement using the wet process relies on pumps to move abrasive slurries of limestone, clay and other crushed particles through pipelines for mixing.
Pulp and paper production: In the paper manufacturing industry, heavy slurries of wood pulp, bleaches, and other caustic chemicals are constantly needing to be pumped from location to location. This slurry often contains abrasive material with large solids that have trouble passing through centrifugal pumps without clogging.

EDDY Pump Equipment for Chemical Processing
The EDDY Pump can be deployed in various dredge configurations to optimize cleanup of sediment and manure transfer. Some of the ideal deployments for agricultural pumping are Excavator Pump Attachments, Self-Priming Pumps, Submersible Pumps, Liner-Safe Dredges, Cable-Deployed Pumps, Autonomous Dredges, Spud-Dredges, and the Subdredge.
Self-Priming Pump
Most EDDY Pumps are submersible, with a self-priming unit, the pump and power unit are not submerged. The suction hose goes into the slurry and the unit acts like a super-sized wet/dry vacuum. This type of pump can remove air on its own and continue operation without assistance, making it perfect for mounting on a trailer that can be wheeled from location to location. Becuase the pump is not submerged, both the operation and maintenance of self-priming pumps are economical and relatively easy.
Submersible Pump
A submersible EDDY Pump operates by being completely submerged in liquid. These types of pumps are designed to work with the entire assembly, consisting of pump and motor, fully submerged in the liquid or medium to be processed. Submersible pumps do not need to be primed because they are constantly primed by being submerged in liquid. A submersible pump operates by pushing, as opposed to drawing, liquid during the pumping process. This is extremely efficient because the pump uses the head of liquid in which it is submerged to operate and no energy is spent in drawing the liquid into the pump. The motor is cooled by the liquid around it, preventing overheating.
Excavator Dredge Pump Attachment
The EDDY Pump Excavator Dredge Pump Attachment is one of our most popular units. Highly versatile for many applications.
The EDDY Pump Excavator or Backhoe mounted dredge pump is the quickest and most cost-effective way for a sand and aggregate plant to begin properly pumping.
The sand and aggregate mine in a matter of hours can connect the EDDY Pump attachment and cutterhead to one of their existing excavators and begin pumping slurries at distances of over two miles directly into their processing plants.
The Backhoe Pump Attachment makes it so that an operator with little or no experience with pumps and dredges can easily master hydraulic dredging in less than a day. The Excavator or Backhoe Pump gets pinned to the end of the backhoe boom and can begin dredging right away.
