Piranha 316 Stainless Steel Corrosion-Resistant Submersible Pump 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 of our corrosion-resistant submersible pumps 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 coated jacketed power cable option includes an epoxy compounded cable entry designed to accommodate your most severe corrosion needs. When it comes to corrosion-resistant pumps, Piranha Pump is your number one source for machines and equipment that fit the bill for your particular needs. When you need a corrosion-resistant submersible pump you can count on us to provide the tools you need to get the job done right.
