G2 Series Electric Submersible Grinder Pumps Information

Features & Benefits

The G2 Series is designed for demanding wastewater applications where effective solids handling and high discharge pressure are essential. Its integrated grinding system reduces solids into smaller particles, allowing wastewater to move efficiently through narrow piping systems without clogging.

With hardened steel cutting components and a robust hydraulic design, the series delivers both performance and durability. These pumps are particularly effective in applications requiring reliable operation under heavy loading and continuous duty cycles.

Construction and Operational Design

The G2 Series features heavy-duty GG25 cast iron construction across key components such as the motor housing, volute, and impeller. This ensures structural strength and long-term durability in aggressive wastewater environments.

The submersible motor operates at approximately 3450 RPM and is designed for continuous duty operation. Available in 460V three-phase configurations, the motors are optimized for reliable power delivery and high hydraulic output.

Each pump includes a stainless steel AISI 316 cable gland for corrosion resistance, along with pre-lubricated bearings and high-performance sealing systems for extended operational life.

Typical Services & Ideal Applications

The G2 Series is specifically engineered for wastewater environments where solids must be reduced prior to pumping. These pumps are commonly used in residential and municipal sewage systems, industrial wastewater transfer, lift stations, and systems requiring high discharge pressure.

Their ability to grind solids while maintaining high hydraulic performance makes them ideal for installations with long discharge lines, vertical lift requirements, or restricted pipe diameters. The combination of durability, monitoring features, and powerful grinding capability allows the G2 Series to perform reliably in even the most demanding applications.
