Why This Product

Submersible Sewage Construction — Continuous Submerged Duty

Motor is sealed for continuous submerged operation. Oil-filled motor section dissipates heat into the surrounding fluid. Cast iron construction throughout provides the wear resistance required for continuous sewage service.

Vortex / Channel Impeller — Solids Handling

Vortex impeller allows solids to pass without direct impeller contact — the fluid vortex carries solids through the pump. Channel impeller design provides maximum throughput for high-solids sewage. Select impeller type based on solids content and size.

Compact Design — Fits Standard Manholes

SL and SE series compact dimensions fit standard wet well manholes and sump dimensions without requiring custom basin modifications.

Grundfos Smart Connect — Remote Monitoring

Grundfos submersible pumps support Smart Connect monitoring — automatic level control, runtime monitoring, and alarm notification for remote wet well installations.

Double Mechanical Seal — Extended Service Life

Double mechanical seal in an oil-filled chamber provides redundant sealing protection. The outer seal prevents sewage from contacting the oil chamber — protecting the inner seal from abrasive and corrosive fluid exposure.

Cast Iron Construction — Industrial Grade Durability

Cast iron casing, impeller, and motor housing provide the mechanical strength and corrosion resistance required for continuous sewage pumping service. Cast iron is the industry standard for submersible sewage pump construction.

Important Notices
Electrical Requires correctly rated supply — 380-400-415V, 3-Phase, 50 Hz. Install with correctly rated circuit protection and motor starter. Direct-on-line (DOL) starting method.
Temperature limits Do not exceed max fluid temperature 104°F. Operating outside these limits will damage seals and motor insulation.
Dry running Do not run dry. BM 3A-12NE pumps use the pumped fluid to lubricate the shaft seal — dry running destroys the seal within seconds. Install dry-run protection on all automatic installations.
Maintenance Refer to the Grundfos Installation and Operating Manual (IOM) for correct installation, commissioning, and maintenance intervals. Contact PumpStop for documentation.
