FEATURES
Goulds 2GA Submersible Grinder Pump
This pump is capable of grinding domestic and commercial raw sewage containing small quantities of plastic, rubber, cloth, paper and other non-abrasive solids.
Pump Features
- 2" NPT vertical discharge
- Cutter system designed to reduce sewage to a fine slurry
- Cast iron, semi-open impeller, non-overloading multivane design with pump-out vanes for mechanical seal protection
- Cast iron, volute type for high efficiency
- Adaptable for slide rail system
- Two coat paint system for superior surface protection
- Dual mechanical seal - tungsten carbide/tungsten carbide lower, carbon/ceramic upper
- Includes a small internal Float Leakage Sensor (FLS) used to detect the presence of water in the stator chamber
- 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
Motor Features
- Air-filled, NEMA type B squirrel cage induction motor
- Class F, 311ºF (155 ºC) insulated stator winding
- Designed for a maximum of 15 evenly spaced starts per hour
- Built-in thermal sensors provide an over temperature signal to the Mini CAS (Control and Status) monitoring relay mounted in the control panel
- Common pump motor shaft and compact seal design permit short overhang minimizing shaft deflection
- Motor casings have integral cooling ribs for maximum heat dissipation
- Shaft mounting is a robust maintenance free design featuring pre-greased ball bearings
- The junction chamber is completely sealed off from the surrounding liquid and incorporates a separate gland assembly with a strain relief clamp
Applications

Goulds 1GA and 2GA series Grinder Pumps are built for grinding municipal, commercial and industrial sewage into a fine slurry. These premium pumps are built to export that slurry to high heads in pressure sewage systems. 1GA and 2GA series Grinder Pumps can even grind commercial raw sewage containing small quantities of plastic, rubber, cloth, paper and other non-abrasive solids. 1GA series Grinder Pumps have a discharge size of 1-1/2" and can reach a maximum capacity of 92 GPM and a maximum total head of 117' TDH. While the 2GA Grinder Pumps have a discharge size of 2" and can reach a maximum capacity of 198 GPM and a maximum total head of 178' TDH. Pump features may include a stainless steel cutter system with a cast iron semi-open multivane impeller with pump-out vanes for mechanical seal protection. Volutes are cast iron for high efficiency and may be adaptable for a slide rail system. Two coat paint provides extra protection and corrosion resistance. Internally, a dual mechanical seal guards against leakage. The lower seal has ceramic/ceramic faces, while the upper seal has carbon/ceramic faces. A small internal float leakage sensor can detect water in the stator chamber. When activated the FLS can signal an alarm (through a 24 volt MiniCAS monitoring relay) and stop the pump from operating, if so desired. The MiniCAS relay can be ordered separately or as a built-in option. The motor is an air filled, NEMA type B induction motor with Class F insulated stator winding. Built-in thermal sensors can send a temperature signal to the MiniCAS relay in the control panel. The motor casings have integral cooling ribs for maximum heat dissipation, while the junction chamber is completely sealed from any surrounding liquid. Please note that single phase pumps require a capacitor pack and start relay for proper operation.
