The G2 Series Advantage: Powerful Grinding Performance for Demanding Wastewater Applications
The BJM Pumps G2 Series Submersible Grinder Pumps are engineered to deliver reliable, high-pressure performance in challenging wastewater environments. Equipped with a built-in macerator system, these pumps efficiently break down solids, allowing for smooth transport through narrow piping systems and long discharge runs.
Designed for both domestic and industrial applications, the G2 Series combines rugged construction with advanced grinding technology to handle sewage, liquids with suspended solids, and systems requiring elevated head pressure. With multiple horsepower configurations and robust protective features, the series offers dependable operation in demanding conditions.
Built for High Head and Efficient Solids Reduction
The G2 Series is designed to excel in applications where high pressure (head) is critical. With capabilities reaching up to 226 feet of head and flow rates exceeding 100 GPM depending on the model, these pumps deliver strong performance across a wide operating range.
At the core of the system is a hardened steel grinding mechanism that provides radial and axial cutting action to reduce solids before entering the pump. This ensures efficient operation even in wastewater systems with suspended debris, helping prevent clogs and improving overall system reliability.
Key Features & Benefits
- Built-In Macerator System: Breaks down solids for efficient transport through piping systems
- Hardened Steel Grinding Blades: Provides consistent and durable cutting performance
- High Head Capability: Delivers up to 226 ft of head for demanding pumping applications
- Seal Minder® Monitoring: Integrated probe alerts operators to seal failure conditions
- Thermal Protection System: Dual thermal switches protect against overheating
- Heavy-Duty Construction: GG25 cast iron components ensure durability in harsh environments
Advanced Protection and Monitoring
The G2 Series is designed with built-in protection systems to ensure long service life and reduced downtime. All models include Seal Minder® moisture sensing probes, which detect the presence of moisture in the oil chamber and provide early warning of seal failure.
Additionally, dual thermal switches embedded in the motor windings automatically protect against overheating by interrupting operation when temperature limits are exceeded. This combination of monitoring and protection enhances reliability in continuous-duty applications.
