GOULDS 1GD Dual Seal Submersible Grinder Pumps

The Goulds Water Technology 1GD Dual Seal Submersible Grinder Pumps with optional seal sensor have a silicon bronze, multi-vane semi-open impeller with pump-out vanes for mechanical seal protection. The 1GD has a anti-roping design, where 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. The 1GD is constructed of a heavy duty cast iron, volute type casing for maximum efficiency, and has stainless steel shaft and fasteners.

The dual seals are silicon carbide vs. silicon carbide outer seal and ceramic vs. carbon inner seal, stainless steel metal parts, BUNA-N elastomers. Upper and shaft seals are positioned independently and are separated by an oil-filled chamber. Optional Silicon/Tungsten Carbide outer seal available. The optional seal sensor cord is located in an 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 are 300 series stainless steel. Uses A10-12 guide rail system for ease of installation and maintenance. Single phase pumps now have built-in overload protection. See control panel note on page 3 of the technical brochure.

GOULDS 1GD Dual Seal Submersible Grinder Pumps

Applications

  • Designed for high head sewage applications where a gravity system is not practical
  • Ideal for pressure sewage systems

Features and Benefits

  • Silicon bronze, multi-vane semi-open impeller with pump-out vanes for mechanical seal protection
  • Heavy duty cast iron, volute type casing for maximum efficiency
  • Dual Mechanical Seals
  • Optional Seal Sensor Cord located in oil-filled chamber
  • Stainless Steel Shaft and Fasteners

SPECIFICATIONS
Pump:

  • Solids handling capabilities: 3″ maximum
  • Discharge: 11⁄4″ 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: 104º F continuous duty, 140° F intermittent duty

    • Single Phase:

  • 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.
