Goulds 1GA71H4CD, Grinder Pump, 4 HP, 460 V, 3 Ph, 1-1/2" NPT Discharge, 56 GPM

Description

Goulds 1GA 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
1-1/2" 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 - ceramic/ceramic 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, 311°F (155 °C) 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
