  • Pumps range from 1/2 to 1-1/2 hp
  • Stainless steel bearing housed inside a durable hex rubber bearing preventing damage to the pump shaft

Overview


Little Giant's 4" submersible pumps are built to handle tough water transfer applications. The ceramic bearing sleeve is added for durability. A hex rubber bearing includes an extra-large surface to assure shaft stability and multi-flow channels to keep small particles away from bearing surfaces. A stainless steel up-thrust washer prevents excessive wear in severe applications. An added benefit is the built-in Flomatic check valve that keeps water in the system at all times. A removable suction screen is available on both thermoplastic and stainless steel units and prevents debris from clogging the impellers while providing full-flow performance.
