Product Description
The double suction pump is a highly efficient and stable horizontal split-case centrifugal pump. Compared to other similar types, it offers long life, high efficiency, reasonable structure, low operating costs, and easy installation and maintenance. The horizontal double suction pump is versatile. It is an ideal pump for firefighting, air conditioning, petrochemicals, water treatment, and other industries. Suitable for industrial and urban water supply pumps, it can be used as a water supply pump for factories, cities, power stations, water conservancy projects, petrochemical plants, etc., and also for farmland irrigation. This horizontal single-stage centrifugal pump type is efficient.
Product Features
Double Suction Impeller: The impeller consists of two back-to-back single-suction impellers. The symmetrical design cancels out axial forces, ensuring smooth operation, and the flow rate can be up to twice that of a single-suction pump of the same diameter.
Horizontal Split Case: Suction and discharge ports are located below the pump shaft centerline; both inlet and outlet flanges are on the pump body. For maintenance, only the pump cover needs to be opened to remove the rotor without dismantling system piping.
High Efficiency & Stability: The impeller's hydraulic design uses advanced CFD technology, improving hydraulic efficiency and offering excellent cavitation performance. Impeller dynamic balancing ensures smooth, vibration-free operation. The horizontal double suction pump is efficient.
Structural Design: The shaft diameter is relatively thick, and the bearing span is short, increasing shaft stiffness and extending the life of mechanical seals and bearings. Unique bearing housing design allows lubrication with grease or thin oil; bearing design life exceeds 100,000 hours. Double-row thrust bearings or enclosed bearings can also be used.
Easy Maintenance & Replacement: Shaft sleeves can be made from various materials to prevent shaft corrosion and wear; they are replaceable. Wear rings between pump body and impeller are replaceable, preventing wear on the split case and impeller, facilitating easy replacement, low maintenance costs, while ensuring running clearance and high operational efficiency. Uses packing seals or mechanical seals; sealing device can be replaced without removing the pump cover. The horizontal single-stage centrifugal pump is maintainable.

Pump Performance Curve
FAQ
Q: What is the primary advantage of a double suction impeller?
A: The double suction pump impeller design balances axial forces, reducing thrust bearing load, and allows for higher flow rates compared to single-suction designs of similar size, leading to smoother operation and longer bearing life.
Q: Can this pump handle large flow applications like municipal water supply?
A: Absolutely. The horizontal double suction pump is specifically designed for high-flow duties, making it a preferred choice for large-scale applications such as municipal water supply plants, industrial cooling water circuits, and irrigation projects.
Q: How does the split-case design benefit maintenance?
A: The horizontal single-stage centrifugal pump with a horizontal split case allows easy access to the internal components like the impeller and shaft by simply unbolting and lifting the top half of the casing, eliminating the need to disconnect any piping.
