18" 150 Goulds Centrifugal Pump

316 SS Pump Casing & Impeller

Model 3175L 1180 R

Equipment Technical OverviewThe Goulds Model 3175 series is designed to handle the most demanding heavy-duty fluid, slurry, and stock handling applications across major process industries.

• Size Designation: 18" (18x18-22) indicates an 18-inch suction diameter and 18-inch discharge diameter configuration, built for massive volumetric throughput.
• Pressure Rating: 150 corresponds to an ANSI Class 150 flange configuration, capable of handling working pressures up to 285 PSIG depending on operating temperature
• Metallurgy: 316 SS Pump Casing & Impeller provides maximum corrosion resistance against acidic fluids, black liquor, chemicals, and industrial waste.
• Operating Speed: 1180 RPM indicates the designated operational speed (typically a 6-pole motor configuration at 60 Hz)
• Rotation: R signifies Right-Hand (clockwise) rotation when viewing the pump from the coupling/drive end.

Key Performance CapabilitiesWhile exact flow and head figures depend heavily on the exact impeller trim diameter, the 18-inch frame size typically covers these operational envelopes:

• Capacity: Capable of handling massive flows ranging from 7,500 to over 20,000 GPM.
• Maximum Temperature: Up to 450°F (232°C).
• Impeller Type: Fully open impeller with back pump-out vanes designed to minimize axial thrust and easily clear thick solids or fibrous materials
• Primary Industrial ApplicationsPulp & Paper: Transferring paper stock through 6% consistency, blow tank contents, primary screen rejects, and low NPSH digester circulation.
• Chemical & Petroleum: Handling corrosive evaporator/reboiler loops, abrasive catalyst slurries, and coke fines.
• General Heavy Industry: Industrial waste treatment, mill scale descaling, and high-volume raw water intake.

The Goulds Model 3175L 1180 R centrifugal pump is a robust, refurbished unit, ideal for heavy-duty fluid and slurry handling in various industrial settings. It features a substantial 18-inch suction and discharge diameter, designed to accommodate high volumetric throughput. Constructed from 316 stainless steel, both the pump casing and impeller provide excellent corrosion resistance, making it suitable for handling acidic fluids and industrial waste. This pump is equipped with an ANSI Class 150 flange, capable of managing pressures up to 285 PSIG, depending on the operating temperature, and is suitable for use at temperatures up to 450°F (232°C). Its operating speed is set at 1180 RPM with a right-hand rotational direction. The fully open impeller with back pump-out vanes is specifically designed to handle thick solids and fibrous materials efficiently. Suitable for applications in pulp and paper, chemical, petroleum, and general heavy industries, this pump can manage flows ranging from 7,500 to over 20,000 GPM. It is particularly effective in transferring paper stock, handling corrosive and abrasive substances, and supporting industrial waste treatment processes. This versatile pump is a reliable choice for demanding environments where high performance and durability are essential.
