Goulds 2GA31K3AD 2GA Series 2" Submersible Grinder Pump (11 HP, Three Phase, 230V, 3475 RPM)

The Goulds 2GA31K3AD 2GA Series 2" Submersible Grinder Pump is backed by 170 years of American ingenuity - engineered, built and tested in the USA. Heavy duty cast iron pump body and over-sized ball bearings in the motor ensure superior performance and longevity. The 1GA / 2GA series is the best choice when high head pressure is needed for commercial and municipal sewage.

The 1GA/2GA series is capable of grinding municipal, commercial and industrial sewage. Enjoy a cutter system designed to reduce sewage to a fine slurry utilizing a cast iron, semi-open, non-overloading multivane design impeller with pump-out vanes for mechanical seal protection. Cast iron casing, volute type for high efficiency. Adaptable for slide rail system with two coat paint system for superior surface protection. Float Leakage Sensor (FLS): a small internal float switch is used to detect the presence of water in the stator chamber. Standard on all models. Leakage Sensor Detector Circuit: The FLS, when activated, will cause the patented 24 volt MiniCAS monitoring relay to signal an alarm and, if desired, stop the pump. The MiniCAS 24 volt relay can be ordered separately for installation in a control panel by a UL or CSA certified panel shop or as a built-in option in our control panel.
