The 5 MUSTS for Choosing the Best Slurry Pump

The design of a slurry pump is critical to making sure that the abrasive and often corrosive aspects of the slurry does not destroy the impeller. Additionally, slurry and sludge may contain large unforeseen solids that will inevitably clog many types of pumps. Since most centrifugal pumps have an impeller with a close tolerance to the volute, the abrasive and sometimes corrosive nature of the slurry will quickly wear the volute and ruin the tolerance. This, in turn, causes the pump to lose its suction capability. This causes massive downtime with slurry pumps along with costly maintenance and spare parts.

For this reason, the EDDY Pump is ideal for slurry pumping applications. The EDDY Pump does not have an impeller, but instead a rotor that does not have any critical tolerances. This allows it to pump slurry at rates of 30% and solids up to 12 inches. This is far more than what centrifugal pumps can handle without any failure or need to change wear parts.

Premier Pump Design

The unique design of the recessed rotor creates an Eddy Current as it spins inside the volute.   This method of displacing fluid via the uniquely designed recessed rotor creates a vortex (a circular current of fluid) at the pump inlet that assists with drawing the material to be pumped into the volute, exiting the pump discharge, and pumping the material downstream of the pump to the desired location.  The Eddy Current also keeps particles and solids maintained in suspension which is critical when pumping high viscous, solid-laden material.  The EDDY Pump's ability to pump concentrated solid matter is perfect for moving viscous materials with as much as 40-70% solids by volume; an impossible task for a lot of traditional pump types.  The EDDY Pump can also pass extremely large solids that are almost the size of the liquid inlet and liquid discharge of the pump; these results are beyond the scope of what most other traditional pumps can achieve.

Low Cost of Ownership

An important factor when choosing the best pump for your application goes beyond whether or not the pump can meet the application requirements; there is also the subject of Cost of Ownership and how much it costs you to operate your pump over the course of the pump's lifetime.  Due to the EDDY Pump's ability to pump high viscous and high specific gravity materials with the volume of very high solid and extremely low water content, the cost to pump the material is drastically reduced.  The accruing cost of water that goes along with using pumps that require a high water content to move viscous materials dig very deep into your profits.   

Materials of Construction

The EDDY Pump is made of the highest quality materials and is extremely rugged, abrasion resistant, chemically compatible with most fluids, and capable of withstanding a great deal of punishment that is typically inherent in abrasive, high viscosity, and high specific gravity, slurry applications.  For more information on the EDDY Heavy-Duty High Viscosity and High Specific Gravity pump go to https://eddypump.com/ or give us a call today!
