Projet SN Series Self Priming Well Jet Pump

Summary

Product Identification

The STA-RITE® ProJet™ SN Series are cast iron, self-priming shallow well jet pumps designed for water systems and sprinkling in homes, farms, and cottages. They provide excellent performance with good pressure for wells up to 25' deep. The pumps are self-priming after the priming chamber has been filled with water.

• SND: L 18.7, B 7.1
• SNE: L 21.3, B 7.0
• SNF: L 22.4, B 8.0
• Note: Dimensions are for estimating purposes only. See the official PDF for detailed diagrams.

Pump Performance: Detailed pump performance data (Capacity in gallons per minute, Discharge Pressure PSI, Dynamic Suction Lift, Shut-off Pressure PSI) is available in tabulated form for each model. See the official PDF for exact tabulated values.

Relief Valve Requirements:

• Pumps installed with a Pro-Source® tank require a 100 PSI relief valve.
• Pumps installed with a conventional tank require a 75 PSI relief valve.
• The relief valve must be capable of relieving the entire flow of the pump at relief pressure.
