Product catalog summary

Overview: The document provides detailed information about the SPN Vertical Heavy Duty Close Coupled API 610 Process Pump (OH5) by Ruhrpumpen, highlighting its design, specifications, and applications.

Specifications: The SPN pump is a vertical, single-stage, single-suction centrifugal pump designed according to API 610 and API 682 standards. It features a radial split, volute type, and close-coupled design with inline suction and discharge positions. The pump is driven by an electric motor with the impeller mounted directly on the motor's extended shaft.

Design Features: The pump's casing and covers are pressure-tight and accurately shaped, ensuring reliability and longevity. It includes a corrosion allowance of 3.2 mm or more and is equipped with cast flanges according to ASME B 16.5 300lb or EN 1092-1, PN40 standards. The impeller is a single-suction, closed, one-piece cast with replaceable rings and balancing holes.

Performance and Applications: The SPN pump is suitable for a wide range of applications, including oilfields, refineries, transfer systems, and process industries. It can handle capacities up to 550 m³/h, heads up to 280 m, temperatures up to 260°C, and pressures up to 40 bar. The pump operates at speeds of 1480/2960 min-1 or 1780/3560 rpm.

Materials and Construction: The document includes a detailed material comparison list, specifying materials used for various components like volute casing, pump shaft, impeller, and bearings. Materials comply with German, American, and British standards.

Testing and Quality Assurance: The pump casing and cover are tested to 1.5 times the maximum working pressure. The design ensures low vibration and shaft deflection, enhancing the life of bearings and seals.

Additional Products: Ruhrpumpen offers a range of other pumps, including vertical barrel pumps, volute casing centrifugal pumps, horizontal process pumps, and single-stage horizontal pumps, all designed according to API standards.
