BRJ3WS R2 3WS Submersible Sewage Pump 3? Flanged Discharge, 2½? Solids Handling

Product catalog summary

Specifications:
The 3WS Submersible Sewage Pump is designed for handling wastewater with a maximum solid size of 2.5 inches. It features a 3-inch discharge size with a 125# ANSI flange and a maximum capacity of 470 GPM. The pump can achieve a maximum total head of 65 feet and includes 300 Series stainless steel fasteners and a 20-foot power cord. The impeller is made of cast iron, ASTM A48, Class 30, with a two-vane semi-open, non-clog design, and a silicon bronze option is available. The casing is heavy-duty gray cast iron, ASTM A48, Class 30, with a volute type design.

Mechanical Seals:
The pump includes dual mechanical seals with silicon carbide vs. silicon carbide outer seal and ceramic vs. carbon inner seal. The seals are separated by an oil-filled chamber, allowing the pump to run dry without damage.

Motor Information:
The motor features Class “B” insulation, an oil-filled design, and is available in single and three-phase options. It supports various voltages and horsepower ratings, with built-in overload protection. The motor is designed for continuous duty with a maximum ambient temperature of 104º F for continuous duty and 140º F for intermittent duty.

Performance Curve:
The performance curve indicates the pump's efficiency across different capacities and total dynamic head measurements. The pump is tested to UL 778 and CSA 22.2 108 standards.

Materials of Construction:
Key components include a non-clog impeller, cast iron castings, a 300 Series stainless steel shaft, and fasteners. The power cable is STOW rated, and the seals use BUNA-N elastomers.

Applications:
The pump is suitable for sewage systems, flood and pollution control, dewatering/effluent, and use in farms, hospitals, trailer courts, and motels.
