SXD Centrifugal Water Pump (ISO Standard Double Suction Pump)

This SXD single-stage double-suction centrifugal pump DAMEI provides to you is a reliable pumping apparatus designed based on the world advanced technologies, a latest high efficiency and energy-efficient centrifugal pump. Compared with other counterparts, this single-stage double-suction pump enjoys quite low NPSH. Its impellers, whose design has been optimized with the assistance of CFD, TURBO and other word-class auxiliary design software, not only promote the working efficiency of the pump but also reduce the running cost. Pumps of this model enjoy a wide range of flow rates and heads, satisfying customers’ needs in different applications.

Thanks to its reliable performance, this single-stage double-suction pump has been applied in the urban water supply and discharge, industrial production, mining and agricultural irrigation. It could be also used in the projects where corrosive or abrasive materials need to be conveyed such as the Yellow River Diversion Project, conveyance of seawater and oil products.

Features of Single-Stage Double-Suction Centrifugal Pump 

1. High Efficiency
Making full use of patent design software and world-class hydraulic models, we have optimized our designs for impellers and pump casings of this single-stage double-suction centrifugal pump in hope of minimizing hydraulic loss and promoting the pump’s working efficiency which is averagely 5% to 15 % higher than that of other double-suction pumps. The impeller rings, made of unique anti-abrasion materials, enjoy long service life and high energy efficiency.

2. Excellent Suction Performance
This industrial centrifugal pump is excellent in its suction performance and cavitation performance. It could operate smoothly at a high speed. The low-speed units of this model are quite suitable for working conditions where the suction head lift and temperature are quite high.

3. Multiple Applications
Apart from the standard materials, this single-stage centrifugal pump could be used to convey other materials. Especially, the high-speed units, which are made of various materials(except that of the media) such as gray iron, ductile iron, steel, stainless steel, Ni cast iron, copper and other wear-resistant,corrosion-resistant and anti-crystalline materials, could be applied in the conveyance of a wide range of materials.

4. Smooth Operation, Slight vibration and Lower Noise
Since its impeller is designed with a double-suction structure and its pump casing a double-vortex structure as well as the distance between each two bearings is minimized, this single-stage double-suction centrifugal pump is highly credited for its smooth operation, slight vibration and lower noise. It could operate quietly and stably even in a ship.

5. Long Service Life
Made of quality materials and equipped with a double-vortex casing, this industrial pump enjoys a longer service life for this scientific design helps extends the service life of such quick-wear parts as the sealing parts, bearings and impeller rings.

6. Laconic Structure
We have conducted stress analyses on key pump elements with the help of specialized software. By this way we could determine the thickness of pump casing and eliminate internal stress, making sure the pump to enjoy both high strength and a laconic structure.

7. Easy Maintenance
This double-suction centrifugal pump makes it easier for users to inspect and maintain rotors and other internal quick-wear parts such as bearings and sealing parts. They could have a quick access to those parts by opening the pump casing, never bothering themselves to dismantle the pipes, coupling nor motor. The standard unit of this model rotates clockwise if you look at it from the motor. We could also provide pumps that rotate anti-clockwise as long as you bring forward the requirement when you place order.
