DINKONDA GLOBAL Power Plants Special SN Series 100～1200 m³/h Two-stage Double Suction Horizontal Centrifugal Pump, Horizontal Multi-stage Condensing Pump

Product Overview
The SN type two-stage double suction horizontal centrifugal pump is a two-stage impeller, double suction inlet horizontal open type centrifugal pump, commonly used as a condenser condensate pump, and can also be used for high flow medium head water supply and drainage conditions. The pump body adopts a horizontal split structure, and maintenance does not require dismantling of the inlet and outlet pipelines. It is equipped with two-stage double suction impellers, which have the characteristics of smooth operation, excellent cavitation performance, and reliable axial force balance. It is mainly used for condensate transportation of thermal power generation units, and is also suitable for medium transportation in metallurgy, chemical industry, and large-scale water supply systems. It can transport clean condensate water with a temperature not higher than 80 ℃ or other media with physical and chemical properties similar to clean water.

Structural Composition
1. Pump body and pump cover: a horizontal open structure, the pump body and pump cover are made of cast iron/steel materials, and the inlet and outlet are arranged in the lower half of the pump body. When disassembling and repairing, the pump cover can be opened to inspect internal components such as impellers, shafts, bearings, etc., without the need to remove pipelines and align with the motor, making maintenance and repair convenient.

2. Two stage double suction impeller: equipped with two stage double suction impellers, the medium enters from both sides of the impeller at the same time, greatly reducing axial thrust; The two-stage series arrangement achieves medium to high head output, and the hydraulic model has been optimized for high efficiency and strong anti cavitation ability, making it suitable for negative pressure suction of condensate water.

3. Pump shaft and shaft seal components: The pump shaft is made of high-quality alloy steel, which has high strength and good torsional resistance; The shaft seal can be selected as mechanical seal or packing seal, suitable for low-pressure and negative pressure operation of condensate water, effectively preventing air suction and ensuring the vacuum degree of the condensate pump system.

4. Bearing components: Both ends are equipped with sliding bearings (rolling bearings are optional), lubricated with oil, and the bearing housing is independently set, with low operating vibration; By relying on the dual suction impeller's own structure to balance most of the axial forces, the residual axial forces are borne by the bearings, ensuring smooth operation of the entire machine.

5. Base: The overall steel common base is shared by the pump and motor to ensure alignment accuracy, reduce unit operation vibration, and facilitate on-site installation and alignment.

Product Features
1. Horizontal split structure, easy to maintain: split shell with split structure, no need to disassemble the inlet and outlet flange pipelines for repairing impellers and seals, shortening the downtime for unit maintenance.

2. Two stage double suction impeller with excellent cavitation performance: the double suction liquid structure has a large inlet flow area, and the NPSHr must have low cavitation allowance, which is suitable for the negative pressure inlet condition of the condenser and is not prone to cavitation, making it suitable for the transportation of condensate water in power plants.

3. Reliable axial force balance: The double suction impeller structure offsets most of the axial force, resulting in low vibration during unit operation and long bearing service life.

4. High operating efficiency: Mature hydraulic models have high interval operating efficiency, reducing the power consumption of power plants.

5. Sealing options are available: packing seal and mechanical seal. The mechanical seal option ensures no medium leakage and prevents air from being sucked back into the condensate system.

6. Horizontal layout, stable operation: Horizontal installation, good rigidity of the whole machine, suitable for long-term continuous and uninterrupted operation, meeting the 24-hour continuous work requirements of thermal power equipment.
