Beneficial Features of the Goulds model 3175 Pump:

The Goulds pumps models was originally introduced in 1968, and since that time there have been tens of thousands of installations worldwide. The following features have contributed to its popularity:

  • Durable Construction:

    These pumps are readily available in 316 stainless steel and cast iron. The pumps are also available in special alloys, such as 317SS, 316LSS, titanium, 6-7% moly, Hastelloy B & C.

  • Excellent Sealing Flexibility:

    Optionally, these pumps are equipped with dynamic seals, which help eliminate mechanical sealing problems, as well as reduce maintenance costs. One of the major advantages of dynamic sealing is that it doesn’t require external seal water. This helps eliminate product dilution, pump contamination, leakage and several other problems.

    Goulds pumps can also come with a TaperboreTM seal chamber. The chamber features a large bore, which helps improve lubrication and cools the mechanical seal. There is a tapered throat as well as a vane particle ejector, which helps keep the solids away from the seal face or avoid solid build-up in the seal chamber. This helps extend the seal life.

  • Low Maintenance and Reliable Operation: The following features contribute to the reliable operation of these pumps:
    • External Adjustment of Impeller:

      Hydraulic performance of the pump can be easily maintained by externally resetting the impeller. This helps in long-term energy savings, as well as minimizing downtime.

    • Durable Shafts:

      The shafts are designed for continuous operations under severe conditions, such as repulper, hydropulper, dry end bloke, etc. The shaft undergoes low deflection at high load, which helps retain long-term sealing and bearing life.

    • Fully Open Impeller:

      The pump features a special warped vane impeller which is ideal for paper stock handling. These back pump-out vanes help prevent entry of solids into the chamber as well as reduce stuffing box pressure.

    • Standard Labyrinth Oil Seals: These seals help to avoid contamination of lubricant, thereby extending bearing life.
    • Replaceable Wear Parts:

      All parts that can wear over time from typical usage, such as the suction side plate, shaft sleeve, stuffing box cover, and throat bushing can be conveniently replaced at low costs.

What are Typical Applications for the Goulds 3175 Pump in the Paper and Process Industries?

The following are common applications for the Goulds 3175 pump in various process and paper industries:

  • Pulp and Paper Mills:

    In this industry, the Goulds 3175 pump is employed in various applications such as low NPSH digester circulation, screening paper stock through 6% consistency, primary screen rejects, high-density chlorine to a washer, floatation cell circulation, etc.

  • Steel Plants:

    The 3175 pump is used in steel plants for mill descaling, waste treatment, electro-galvanizing recirculation, etc.

  • Chemical Plants:

    Goulds 3175 pumps are used in chemical plants for evaporator and reboiler circulation, as well as slurry services.

  • Food Industry:

    The 3175 is excellent for pumping slurries like fruit pulps, spent grains, grain mash, beet and sugar, and corn products.

All the above information demonstrates why the Goulds 3175 pump has been and continues to be very popular throughout the past five decades.
