Description
The Barnes BASIN, 120-575 barnes basin cover for step & sgv pumps (094709). Effluent pumps are designed for handling dirty water in typical septic tank and effluent applications. High temperature models are available. Barnes effluent pumps are designed to handle most low and high head effluent applications. Series capacity up to 87 GPM at 109 TDH head.
Submersible Construction — Continuous Duty
Cast iron construction rated for continuous submerged operation. Oil-filled motor dissipates heat into surrounding fluid — enabling 24/7 duty cycle operation without overheating.
2" Solids Handling
2" spherical solids passage allows tissue, personal care products, and residential sewage materials to pass without clogging — the minimum specification for residential sewage service under most plumbing codes.
Thermal Overload Protection — Auto Reset
Automatic thermal overload shuts the motor down on temperature exceedance and resets after cooling. Prevents permanent motor damage from blocked discharge, run-dry, or overload conditions.
Multiple Switch Configurations
Available with no switch (manual), vertical float, wide-angle float, and piggyback switch types — select the configuration matched to your basin geometry and automatic operation requirements.
Cast Iron Volute and Impeller
Cast iron construction provides wear resistance required for sewage service. Cast iron is the industry standard material for residential and commercial sewage pump applications.
