Description
The Barmesa 3BSV-503DS is a 5.0 HP, 3-Phase, 230V submersible stainless vortex sewage pump. These pumps efficiently handle sewage and wastewater, particularly in corrosive environments where stainless steel construction is essential . Common applications include sewage treatment plants, industrial facilities, and commercial buildings. They play a crucial role in maintai 3" (7.62 cm) NPT flange. Includes flanged discharge. Part Number 72090075
Submersible Solids Handling — Sewage and Sludge Ready
Designed for pumping sewage, sludge, and water containing solid particles in industrial, municipal, and commercial applications. Open double-vane impeller passes spherical solids up to the rated diameter without clogging.
Open Double-Vane Impeller — Solids Passage
Open, double-vane impeller design maximizes solids passage with minimum clogging risk. Dynamically balanced to ISO G6.3 specification — reduces vibration and extends bearing service life in continuous duty applications.
Silicon Carbide Mechanical Seal — Long Life in Abrasives
Silicon carbide (SiC) seal faces resist abrasive wear from solids-laden fluids. Single mechanical seal in an oil-filled chamber provides reliable sealing with significantly longer service intervals than conventional seals.
Cast Iron Construction — Industrial Grade
Volute, motor housing, and impeller in cast iron ASTM A-48, Class 30 — the industry standard material for submersible sewage pump construction. Provides the strength and corrosion resistance required for continuous submersible operation.
416 Stainless Steel Shaft
416 stainless steel shaft provides corrosion resistance at the seal interface and superior strength over standard mild steel shafts. Resistance to corrosion at the seal face is critical for long-term seal integrity.

- Do not use the pump to handle explosive or corrosive liquids.
- This pump is not approved for use in swimming pools, recreational facilities, or any application where human
- Do not operate the pump dry for extended periods; this may damage the motor or the seal.
- Testing is performed with water specific gravity of 1.0 @ 68 °F (20 °C); other fluids may vary
| Fluid compatibility | For use with clean water and non-explosive liquids compatible with pump materials. Never use with explosive, flammable, or corrosive fluids unless specifically rated. |
| Swimming pools | Not approved for use in swimming pools, recreational installations, or any application where human contact is common. |
| Temperature | Do not exceed maximum liquid temperature rating (104 °F (40 °C) PUMP CASING 316 series stainless steel MOTOR COVER 316 series stainless steel). Exceeding limits causes seal and motor damage. |
| Electrical | Requires properly sized, grounded branch circuit with correctly rated motor starter and thermal overload protection. |
