Goulds 3175 8x10-22 Paper Stock Process Pump 316SS

The Goulds Model 3175 is a heavy-duty centrifugal pump designed specifically for demanding applications in the pulp and paper industry, as well as other process services handling fibrous slurries, solids-laden fluids, and corrosive materials. This 8x10-22 size features a large suction inlet (10 inches) and discharge (8 inches) with a maximum impeller diameter of 22 inches, making it ideal for pumping paper stock up to 8% consistency, sludges, and slurries with large soft solids. Constructed with 316 stainless steel wetted parts, it offers excellent corrosion resistance and durability in harsh environments. Key benefits include high efficiency, easy maintenance with back pull-out design, and adjustable impeller clearance for sustained performance. Compared to similar pumps like those from Sulzer or Flowserve, the 3175 provides superior solids-handling capability and lower NPSHr, reducing cavitation risks. Drawbacks may include higher initial cost and the need for precise alignment during installation. It is widely used in recycling, wastewater treatment, and chemical processing. This unit appears used with visible wear but remains functional, offering cost savings over new models.
