When it comes to performance and efficiency, you count on Little Giant to deliver what you need -- with pumps that move water reliably for years to come. That's why we're excited to announce the transition of our 4" submersible well pump line to a new and enhanced hydraulic design that’s been re-engineered using the latest techniques available to improve fluid flow efficiencies. The Little Giant 4" submersible well pump line features the best technology and materials available in the pump industry suited for longevity in clean water pumping applications, including:

• All stainless-steel components are 300 series grade or better
• Industry-standard discharge head and NEMA motor connection bracket produced with proven, reliable, and durable materials (available in 300 series stainless steel or engineered thermoplastic resins)
• Plastic outlet connection pumps have a Flomatic VFD style check valve; stainless steel connection pumps are equipped with a wafer disc-style check valve
• Pump hydraulics are driven by stainless steel, 7/16-inch hex shaft with a rigid top bearing and splined motor coupling for maximum power distribution efficiency
  These pumps will be available in eight performance ranges: 5, 8, 10, 12, 16, 18, 22, or 26 GPM with horsepower ranges from ½ through 5. They have been designed to exceed all industry standards for quality manufacturing processes and operational safety.
