The BSC50 Series Sump and Light Effluent pump combines high performance and heavy duty construction features with light solids handling. The powerful 1/2 horsepower PSC motor moves water quickly to either protect your basement or operate your septic system with higher heads or flow. The simple and effective design is a great option for newly built basements and septic installations. The bottom volute intake teeth prevent debris from getting ingested and clogging the system while allowing 3/8″ solids to pass right through.
