The 1GA/2GA series of Grinder Pumps from Goulds Water Technology are designed for municipal, commercial, and industrial pressure sewage systems or applications that require high head.
This series has a cutter system designed to reduce sewage to a fine slurry. The cast iron, semi-open, non-overloading multi-vane impeller features pump out vanes for mechanical seal protection.
Cast iron, volute type casing provides high efficiency operation and can adapt for a slide rail system. A two coat paint system also adds superior surface protection.
A float leakage sensor comes standard on all models. A small internal float switch is used to detect the presence of water in the stator chamber. The float leakage sensor, when activated, will cause the patented 24 volt MiniCAS (control and status) 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 the control panel.
The 1GA/2GA Series from Goulds Water Technology Water Technology features an air filled, NEMA type B squirrel cage induction motor. The motor is designed for 15 evenly spaced starts per hour and features built in thermal sensors that provide an over temperature signal to the Mini CAS monitoring relay mounted in the control panel. A common pump motor shaft and compact seal design permits short overhang, minimizing shaft deflection. Motor casings have integral cooling ribs for maximum heat dissipation and the 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. This series is also available in optional Explosion Proof construction.
