Product Introduction

The double-suction pump is a high-flow fluid conveying device with a "horizontal single-stage double-suction centrifugal pump" as its core structure. Its iconic dual water inlet design can simultaneously draw medium from both sides of the impeller, breaking the flow limitation of single-suction pumps. It is specially designed for "high-flow, high-stability" conveying scenarios such as municipal water supply (such as urban pipeline water supply), power plant circulating water (such as condenser cooling water supply), agricultural irrigation (such as large irrigation area water supply), and chemical park circulating water. It is the core power equipment in large-scale engineering fluid conveying systems.

Core Structural Features

Double suction pump core structure

Double water inlet symmetrical impeller design
The impeller structure adopts symmetrical water inlet on both sides, which can increase the flow rate by more than 30% compared with the single-suction pump of the same caliber. At the same time, the symmetrical water inlet method makes the hydraulic distribution of the medium more uniform in the impeller, reduces the generation of local vortexes and reduces hydraulic losses. It not only improves the flow output capacity, but also lays a structural foundation for the stable operation of the equipment.

Horizontal split pump body for easy maintenance

The pump body splits horizontally along its axis, forming an "upper cover + lower pump body" structure. During routine maintenance or component replacement, the rotor (impeller, pump shaft, etc.) can be directly removed by simply opening the upper cover, without disassembling the inlet and outlet pipes or the motor. This significantly shortens maintenance time and minimizes the impact on the overall conveying system. It is particularly suitable for projects requiring high continuous operation.

Axial force self-balancing structure

Relying on the symmetrical structure of the double-suction impeller, the axial thrusts generated by the water entering on both sides can offset each other, eliminating the need for additional balancing devices such as balancing discs and balancing drums. This simplifies the internal structure of the pump body and reduces equipment problems caused by failure of the balancing device. At the same time, it avoids additional impact of axial force on the bearings, significantly extending the bearing service life and reducing equipment maintenance costs.

Performance Advantages

Large flow output capacity

With its dual-inlet design and optimized hydraulic channels, a single pump can achieve a maximum flow rate of several thousand cubic meters per hour (for example, a large double-suction pump can reach a flow rate of over 5,000 m³/h). This can meet the flow requirements of large-scale projects such as centralized water transmission from urban water supply plants to pipelines and high-flow water replacement in power plant circulating water systems. It eliminates the need for multiple pumps in parallel, simplifying system configuration.

Low vibration and low noise operation

The symmetrical water inlet structure reduces the hydraulic impact of the medium entering the impeller. The vibration amplitude of the equipment during operation is 20%-30% lower than that of a single-suction pump, and the operating noise is 5-10dB (decibels) lower than that of a single-suction pump. This meets the strict noise control requirements of municipalities, power plants, and other scenarios in the operating environment, improves the comfort of the working environment, and reduces the long-term damage to equipment and pipelines caused by vibration.

Highly efficient and energy-saving operation performance

By optimizing the hydraulic model through fluid dynamics simulation, the pump's operating efficiency can reach over 90% (some high-performance double-suction pumps can achieve 92%-95%), and the high-efficiency operating range is 25%-30% wider than that of ordinary pumps. Even under conditions of fluctuating flow, high efficiency can be maintained. In long-term operation, it can save 10%-15% of energy consumption compared to inefficient pumps, reducing long-term operating costs for users.
