4-Inch Submersible Well Pump

Little Giant offers a complete line of 4" submersible pump products designed for pressured water transfer from wells, cisterns, ponds, lakes, or streams. These pumps are constructed of durable, abrasion-resistant materials and reach peak performance when wholly submerged.

Features & Benefits

  • Available in thermoplastic or stainless steel options
  • 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
  • Engineered thermoplastic hydraulic staging facilitates close tolerances for increased performance
  • Internal check valve integrated into each pump
  • 1-1/4" FNPT Discharge
  • Removable suction screen

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.
