The double-suction pump, as an important form of centrifugal pump, is widely used in engineering due to its features such as high head and large flow rate. The impeller of the horizontal clear water double-suction pump is actually composed of two back-to-back impellers. The water flowing out from the impeller converges into a volute. The double-suction pump has the following characteristics: It is equivalent to two identical diameter single-suction impellers working simultaneously, and the flow rate can be doubled under the same impeller outer diameter; The pump casing is horizontally split in the middle, which is convenient for inspection and maintenance; At the same time, the inlet and outlet of the double-suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the layout and installation of the pump and the inlet and outlet pipes; The impeller structure of the double-suction pump is symmetrical, without axial force, and runs more smoothly.

The inner surface of the pump casing and the surface of the impeller are extremely smooth, with remarkable anti-cavitation performance and high efficiency.
Sealing: Select BURGMANN mechanical seal or packing seal. It can ensure no leakage for 8,000 hours of operation. Bearings: Select SKF and NSK bearings to ensure smooth operation, low noise, and long service life.
Installation form: Assembly does not require adjustment. It can be installed in a stand-alone or horizontal manner according to the on-site usage conditions.

Core Strengths

A mature and reliable hydraulic model
The impeller and volute profiles are optimized based on classical fluid mechanics and decades of engineering practice, taking into account efficiency, head, and anti-cavitation performance. The flow passage is smooth, with low hydraulic losses, and high energy conversion efficiency.
Precise manufacturing and dynamic balancing process
The rotor components (impeller and shaft) are machined with high precision. The impeller undergoes strict static and dynamic balance checks, with extremely low residual imbalance. This ensures the stability and reliability during high-speed operation from the very beginning.
Heavy-duty bearings and reliable sealing system
Large-sized heavy-duty rolling bearings are used, with strong bearing capacity and long design life. The bearing box has good rigidity and sufficient heat dissipation. The shaft seal can be selected from modular mechanical seals or flexible packing seals, and is equipped with corresponding flushing, cooling or leakage monitoring schemes to ensure long-term no-leakage operation.
Standardized interfaces and system compatibility
The installation dimensions comply with international and national standards such as ISO 2858 / GB/T 5656, and are highly compatible with mainstream motors, bases, and pipeline accessories. Vibration and temperature monitoring sensor interfaces are reserved to facilitate the connection of modern pumping station intelligent monitoring systems.
