Two-Stage Double Suction Centrifugal Pump: Unrivaled Reliability and Power for Industry
Introducing a highly efficient two-stage double suction centrifugal pump with a bisected volute casing, engineered for the most demanding operating conditions. This pump is the culmination of years of experience and innovative engineering solutions, guaranteeing exceptional performance and uncompromising reliability. It's perfectly suited for applications requiring the transfer of large fluid volumes under high head, such as metallurgical plants, power stations, large pumping stations, and other industrial facilities.
Exceptional Performance and Innovative Design
This powerful unit is designed to transfer water or similar liquids at temperatures ranging from -10 °C to 80 °C. With a 250 mm discharge nozzle and a 200 mm suction nozzle, the pump is ready to handle intense flows. It's driven by a high-voltage motor with a colossal power output of 790 kW, demonstrating its capability to tackle the most challenging tasks.
Boasting a maximum flow rate of 1020 m³/hr and a maximum head of 221 m, this pump delivers outstanding operational characteristics. The innovative design, featuring double suction on the first stage and single suction on the second, significantly improves anti-cavitation performance, ensuring stable operation and reducing axial dimensions. An optimal rotational speed of 1480 rpm effectively prevents vibrations caused by high speed, contributing to the equipment's extraordinary longevity.
Efficiency, Reliability, and Ease of Maintenance:
Thanks to the double volute design of the pump casing, radial force is significantly reduced, enhancing stability and overall operational reliability. The pump's design was executed using advanced hydromechanical software, 3D modeling, and strength verification, guaranteeing its high efficiency, stability, and flawless reliability.
Maintaining this pump is exceptionally straightforward: its rolling bearings can be lubricated with both grease and liquid oil. Nozzles are integrated into the pump casing, and for major overhauls, you simply lift the pump cover. This provides easy access to internal components and minimizes downtime.
Seal Durability and Operational Flexibility:
The standard fully mechanical seal ensures leak-free operation for an impressive 8000 hours, guaranteeing cleanliness and operational safety. If needed, the packing seal can be customized to meet your specific requirements. The pump typically rotates clockwise, but individual counter-clockwise rotation can be configured, offering unparalleled flexibility for integration into any system.
This two-stage double suction centrifugal pump is the ideal choice for enterprises seeking a reliable, highly efficient, and easy-to-maintain solution for transferring large volumes of liquids under high pressure. Its thoughtful design and powerful characteristics guarantee uninterrupted operation in the most demanding industrial environments.
