Franklin 10GPM 1/2HP Submersible Cistern Pump (115v or 230v)

Our Franklin 10GPM cistern pump provides high performance and long life for rainwater harvesting applications. Not to be confused with the C1 20GPM models (which are designed for septic tanks), the C1 10GPM is the only C1 model designed for residential primary water supply delivery. The C1 Series pump is able to pass solids up to 1/8" without having a negative effect on the internal hydraulic components.

The pump’s unique bottom suction design allows for maximum fluid drawdown without compromising durability or overall life, and it does not require the use of a flow induction sleeve.  In other words, no pump casing is needed -- just drop the pump in the cistern, and you're ready to go. 

Features:

• Bottom suction design.
• Robust thermoplastic discharge head design resists breakage during installation and operation.
• Single shell housing design provides a compact unit while ensuring cool and quiet operation.
• Hydraulic components molded from high quality engineered thermoplastics.
• Optimized hydraulic design allows for increased performance and decreased power usage.
• All metal components are made of high grade stainless steel for corrosion resistance.
• Available with a high quality 115 V, ½ hp motor
• Fluid flows of 10 gpm, with a max shut-off pressure of over 100 psi.
