Ater Pump 20-Series was specifically designed to be used in septic effluent and cistern pumping where maximum draw down is needed. The 20Series was built using 304 stainless steel and high-wear life thermoplastic ensuring corrosion resistance and longevity. Ater 20Series also has 5 stages for maximum shut-off head pressure of 170ft of head.

Internal diffuser design provides high performance and long life in harsh water conditions. The pump can pass solids up to 1/8 inch with no negative effect on the internal components. The unique hollow-wall design eliminates the need for an induction sleeve as the pump-end is on the bottom and the water passes past the motor on its way to the diffusers, cooling it continuously.

This makes the 20Series the most sought-after unit and highly versatile in application uses:

• Filtered effluent from aerobic septic systems
• Grey water pumping applications
• Filtered effluent service water pumping
• Water reclamation such as rain harvest basin pumping
• Agriculture and livestock water pumping
