The Shredder (SKX) type pumps leave solids slightly larger than if passed through a grinder pump. The shredding action is cause by using a cutting impeller with a Tungsten Carbide Tip against a "spiral" shaped diffuser plate. The SKX -pumps have non-clog impellers designed for high volume and lift performance.
All wear and "wet" parts such as impeller, wear-plate, oil housing, pump-housing, and inner pump top are made of Cast 316 stainless material. The elastomers such as o-rings, lip seals and, gaskets are made of FKM . Standard power cable is made of oil-resistant material. Special installation can be made with EPDM power-cable and elastomers. (BUNA (Nitril) also available).
- 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.
