Goulds 1GD51G5AA Submersible Grinder Pump 2HP 3 Phase 575V

Goulds 1GD51G5AA Submersible Grinder Pump Dual Seal with Optional Seal Sensor Probe 2 HP 3 Phase 575V 4.8 Maximum Amps FEATURES Single phase pumps now have built-in overload protection. See control panel note on page 3. Impeller: Silicon bronze, multi-vane semi-open, with pump-out vanes for mechanical seal protection. Balanced for smooth operation. Grinder Cutter System: The anti-roping design, hardened cutter is keyed to the motor shaft for positive drive. The cutter ring is specially designed to be reversed when the first side wears out thus doubling its life and reducing maintenance costs. The cutter system is designed and tested to pass items found in normal wastewater. Casing: Heavy duty cast iron, volute type for maximum efficiency. Use with A10-12 guide rail system for ease of installation and maintenance. Dual Mechanical Seals: Silicon carbide vs. silicon carbide outer seal and ceramic vs. carbon inner seal, stainless steel metal parts, BUNA-N elastomers. Upper and lower shaft seals are positioned independently and are separated by an oil-filled chamber. Optional Silicon/Tungsten Carbide outer seal available. Optional Seal Sensor Probe: Located in oil-filled chamber. If pumpage should begin to leak past lower seal it indicates to pump control panel a fault has occurred. Requires optional Seal Fail Circuit in the control panel. Fasteners and Pipe Plugs: 300 series stainless steel. APPLICATIONS Designed for high head sewage applications where a gravity system is not practical. Ideal for pressure sewage systems. SPECIFICATIONS Pump: Solids handling capabilities: 3" maximum Discharge: 1 1/4" NPT removable flange Capacities: up to 46 GPM Total heads: up to 106 feet TDH Motor: 2 HP, 3450 RPM, 60 Hz Class "F" insulation Rated for continuous duty fully submerged Maximum Fluid Temperature: 104 F continuous duty, 140 F intermittent duty Single Phase: 208 or 230 volt Built-in, auto reset, on-winding motor overload Three Phase: 200, 230, 460 or 575 volt Class 10 ambient compensated, overload protection required in control panel. MOTORS Fully submerged in oil-filled chamber. High grade turbine oil surrounds motor for more efficient heat dissipation, permanent lubrication of bearings and mechanical seal for complete protection against outside environment. Class F insulation Single Phase: 2 HP, 208 or 230 volt, 60 Hertz, 3450 RPM, 14/4 power cord. Motor has built-in overload with automatic reset. Start capacitor, run capacitor and starting relay are required and will be located in the control panel. See "Recommended Control Panels" in chart on this bulletin. Three Phase: 2 HP, 200, 230, 460 or 575 V, 60 Hz, 3450 RPM. 14/4 STOW. Overload protection must be provided in starter unit. Designed for Continuous Operation: Pump ratings are within the motor manufacturer's recommended working limits and can be operated continuously without damage when fully submerged. Bearings: Upper and lower heavy duty ball bearing construction for precision positioning of parts and to carry thrust loads. Power (Sensor) Cables: Severe duty rated, oil and water resistant. Epoxy seal on motor end provides secondary moisture barrier in case of outer jacket damage and to prevent oil wicking. 20 foot standard with optional lengths available. O-ring: Assures positive sealing against contaminants and oil leakage. Shaft: 300 series stainless steel, keyed design, short overhang for minimum shaft deflection. Pump is capable of running dry without damage to mechanical components.
