Compact Grinder Pump Performance for Reliable Wastewater Handling
The BJM Pumps GRIX Series Submersible Grinder Pumps are designed for efficient wastewater transfer in residential and light commercial applications. Featuring an integrated cutting system, these pumps break down solids at the inlet, allowing wastewater to travel smoothly through narrow or pre-existing piping systems.
With compact sizing, versatile voltage options, and durable construction, the GRIX Series delivers dependable performance for domestic sewage, liquids with suspended solids, and systems requiring high discharge pressure.
Efficient Solids Reduction in Compact Applications
The GRIX Series incorporates a built-in macerator with hardened cutting components that reduce solids before they enter the pump. This ensures consistent performance and minimizes the risk of clogging, particularly in systems with smaller pipe diameters.
Designed for wastewater systems where space and piping constraints are common, the GRIX Series provides an effective solution for maintaining steady flow while handling challenging solids content.
Key Features & Benefits
- Integrated Cutting System: Built-in macerator breaks down solids at the inlet
- Compact Design: Ideal for tight installations and narrow piping systems
- Pressure Capability: Designed for applications requiring higher head performance
- Dual Voltage Options: Available in 230V and 460V configurations
