| Piranha Stainless Steel Pumps Teflon Rhino Coated - Corrosion Resistant Pumps |
| Piranha 316 stainless steel submersibles feature recessed impellers for extra solids handling capability while minimizing abrasive wear. The majority of material pumped never comes in contact with the impeller. Mechanical seals are abrasion resistant silicon carbide. All wetted metal components are 316 stainless steel except the rotor shaft which is 416 stainless steel for extra strength. The volute and impeller are thick generous machined castings of 316 stainless steel (not fabricated sheet metal like other inexpensive pumps). We offer six models 1-10 hp. Our Teflon jacketed power cable option includes an epoxy compounded cable entry designed to accommodate your most severe corrosion needs. |
| Piranha Teflon Rhino coating is actually comprised of two separate coatings: First, the metal surface is hardened by immersion in special chemicals while high voltage electricity is applied. This process changes the metal surface from Aluminum to Aluminum Oxide. Aluminum Oxide also known as Corundum, is the second hardest mineral known to science. This coating is at the top of the hardness scale at 70 Rockwell, and is harder than case hardened or chrome steel. Virtually every person is familiar with this substance, as it is the most common abrasive utilized in sand paper. This coating changes the surface properties of our aluminum providing excellent abrasion and corrosion resistance. The second stage of the process impregnates the Aluminum Oxide surface with Teflon. This coating is fused into the pores of the metal and cannot be chipped, peeled, or scrapped away. Teflon is impervious to virtually all chemicals, salts, and acids regardless of their strength. The resulting two-stage finish allows Piranha pumps to be utilized in corrosive environments, where bare aluminum pumps cannot survive. Though not recommended for extreme corrosion or abrasion resistance, Piranha Teflon Rhino coated pumps are an inexpensive alternative to costly exotic metal pumps for moderately corrosive applications, where reasonable quantities of abrasives may be present. |
