• Heads: to 140 feet (43 m)
• Temperatures: to 225°F (107°C)
• Pressures: to 85 PSIG (586 kPa)
• Suction Lifts: to 25 feet (7.6 m)
• Spherical Solids: to 3 inches (76 mm)

Mechanical / Hydraulic

The Goulds Trash Hog is engineered for heavy-duty solids handling services, featuring:

• Self-Priming Capability: Large capacity priming chamber for reliable priming and repriming. All Trash Hog sizes will prime up to 25 feet in under 5 minutes. An elevated suction inlet keeps liquid in the priming chamber even if the check valve fails.
• Solids Handling: Non-clog impeller capable of passing spherical solids up to 3 inches (76 mm). Uses two-vane or three-vane impellers.
• Maintenance Features:
  • External Impeller Adjustment: Easily renews optimum hydraulic performance by compensating for wear without disassembly or draining the pump.
  • Back Pull-Out Design: The complete power end with seal chamber can be easily removed from the casing without disturbing suction and discharge piping. No special tools or shims are required for clearance adjustments.
  • Lightweight Clean-Out Cover: Allows access to remove debris.
  • Renewable Wearplate: Provides added protection to the pump casing from abrasive wear and allows running clearances to be maintained.
  • Tapered shaft and woodruff key design for easy impeller removal.
• Durability Features:
  • Heavy Duty Power End: Provides rigid shaft support and ample oil volume for cooler running bearings and extended life.
  • Heaviest shaft and bearing assembly in the industry, with a long bearing span and large shaft diameter for minimal deflection and maximum mechanical seal life.
  • Rigid cast iron frame foot for excellent support.
  • High Strength Stainless Steel Tapered Shaft for maximum strength and corrosion resistance.
  • Silicon Carbide Mechanical Seal (hard faces for higher wear resistance; Carbon/ceramic seal is optional).
  • Back Pump-Out Vanes and Rear Impeller Ring: Reduces seal chamber pressure and axial thrust, prevents solids from entering the seal chamber.
  • Class 125 Flanges: Standard on suction and discharge for positive sealing.
  • Replaceable Elastomeric Check Valve with integral blow-out disc.
