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 internal check valve integrated into each pump 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.
