Two-stage centrifugal pump with double suction: Reliability and Power for Industrial Applications

Introducing a highly efficient two-stage centrifugal pump with double suction and a bisecting spiral chamber, designed for the most demanding operating conditions. This pump is the result of many years of experience and advanced engineering solutions, guaranteeing exceptional performance and reliability. It is ideal for applications requiring high flow rates and high head, such as metallurgical plants, power stations, large pumping stations, and other industrial facilities.

Key Features and Benefits:

High Performance: Designed for pumping water or water-like liquids with temperatures ranging from -10 °C to 80 °C. The diameter of the discharge pipe is 150 mm, and the suction pipe is 200 mm. The pump is designed for an inlet pressure of up to 2.5 MPa and an outlet pressure of up to 4.0 MPa, aggregated with a 450 kW high-voltage motor.

Innovative Design: The use of double suction in the first stage and single suction in the second stage significantly improves anti-cavitation characteristics, reducing the axial dimensions of the pump and ensuring stable operation.

Reduced vibration: Operates at an optimal speed of 1480 rpm, which effectively prevents vibrations caused by high speeds and contributes to the durability of the equipment.

Efficiency and Reliability: The double spiral design of the pump chamber significantly reduces radial force, increasing operational stability. Design using advanced hydromechanical software, 3DM modeling, and software-based strength testing ensure high efficiency, stability, and reliability of the pump.

Ease of Maintenance: Rolling bearings with grease or oil lubrication simplify maintenance. The pipes are integrated into the pump housing, and for major repairs, simply lift the pump cover, which greatly facilitates access to internal components.

Seal Durability: The standard fully mechanical seal ensures no leaks for 8,000 hours of operation. The packing seal can be adjusted to suit your needs.

Flexibility in Operation: The standard pump rotation is clockwise, but counterclockwise rotation can be customized.

This two-stage centrifugal pump is the ideal choice for companies looking for a reliable, highly efficient, and easy-to-maintain solution for pumping large volumes of liquids at high pressure.
