Barmesa Submersible Grinder Pumps
The Barmesa Submersible Grinder Pump Series is engineered to macerate and pump wastewater containing solids, debris, and sewage materials before they enter discharge piping. By utilizing hardened grinding components and vortex hydraulic designs, these pumps reduce solids into smaller particles, helping prevent clogs, blockages, and costly system downtime in residential, commercial, municipal, and industrial wastewater systems.
The series includes the BGP-DS and BGPH-DS families, with horsepower ratings from 2 HP to 7.5 HP and discharge configurations ranging from 1¼-inch threaded outlets to 2½-inch ANSI flanged connections. Engineered for demanding wastewater service, these pumps combine powerful grinder mechanisms, heavy-duty cast iron construction, and oil-filled motors to deliver reliable solids reduction and wastewater transfer.
Advanced Grinding Technology & Rugged Construction for Long Service Life
At the core of the grinder series is a robust cutting system designed to process solids before they enter the discharge line. These components work together to efficiently macerate solids and help protect downstream piping systems from obstructions and blockages. Barmesa grinder pumps are built using materials selected for wastewater durability and corrosion resistance.
Key grinder components include:
- Hardened 440C stainless steel radial cutters
- Hardened 440C stainless steel shredding rings
- Rockwell C-55 hardness grinding components
- Precision-engineered vortex impellers
- Dynamic impeller balancing for smooth operation
Construction features include:
- Cast iron volutes
- Cast iron motor housings
- Cast iron seal plates
- 420 stainless steel shafts
- Stainless steel hardware
- Buna-N elastomers and seals
- Oil-filled motors and seal chambers
The heavy-duty design helps provide dependable service in municipal lift stations, pressure sewer systems, septic applications, and industrial wastewater environments.
Seal Protection and Monitoring
The grinder series utilizes double seal protection with oil-lubricated seal chambers to improve reliability in demanding operating conditions.
Additional protective features include:
- Double mechanical seal systems
- Silicon carbide seal components
- Carbon ceramic secondary seal elements
- Moisture sensors
- Temperature sensors on select models
- Class F motor insulation
- Overload protection compatibility
These features help maximize pump life while providing early warning of service-related issues.
