SV Series:

The SV-pumps are equipped with Vortex impellers, undoubtedly the best non-clog impellers ever invented for the handling of mud, raw sewage, viscous liquids, rags, wood chips and other solids. They pass solid up to 90% of pump outlet diameter. 

• Longer Power Cord – Standard 33ft. power cord on pumps ½ HP and below and 50ft. on pumps 1HP and above.
• 304SS Motor Housing – Superior abrasion resistance will not wear out like aluminum motor housings when pumping sandy water.
• Three Seal Motor Protection - Motor is protected by double mechanical seals. Lower seal made of silicon carbide/silicon carbide and upper seal is made of carbon/ceramic. An additional lip seal has been installed above the impeller, to help prevent abrasives such as dirt, silt or sand, from entering into the seal chamber.
• More Motor Protection – Winding protection and (NEMA) Class F motor insulation allows motor temperature to raise to 230°F, superior to pumps with Class A and B insulation. Automatic switch turns pump motor off if temperature and/or amp draw raises too high. When the motor cools the switch will automatically reset and the pump will turn back on.
• Tough Pump Construction – Hardened cast iron stands up to rough handling and pumping sandy water unlike pumps with soft resin impellers or plastic exterior components.
