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.
