  The SYW vertical cast iron double-pipe sewage submersible pumps developed by PWS represents a breakthrough in sewage submersible pumps technology, combining robust engineering with high-performance capabilities. As a cast iron water pump specifically engineered for extreme operating conditions, this heavy-duty equipment excels in deep-well applications, high-head scenarios, and handling media with large abrasive particles.
 

Technical Features

  • Space-Saving Vertical Design
Its vertical structure places the pump body underwater while the motor stays above the liquid. It occupies minimal space, requires no pump chamber, and features effortless installation.
  • Reliable Cavitation Resistance
Optimized runner geometry plus balanced impeller and volute components greatly lower cavitation occurrence, prolonging the pump’s service time.
  • Stable Safe Coupling Design
Precision couplings connect the pump and motor. The accurately machined pump shaft runs smoothly and comes with a generous safety factor.
 

Product Advantage

  • Non-cloggingDesign

The impeller adopts a single or double channel form, similar to a uniform cross-section elbow pipe structure, which can effectively pass fibrous substances (such as hair, fabric) three times the pump diameter and solid particles (such as sand, gravel, sludge blocks) up to 40% of the pump diameter, significantly reducing the risk of clogging.

  • DoubleTubeSupportStructure

External pipeline water within pipe support and double structure, running more stable, less vibration, compared with the single pipe pump, 60% increased resistance to bending capacity, suitable for deep well working condition

 

Application Scenarios

  • Industrial Wastewater Treatment
Suitable for chemical, pharmaceutical, mining, papermaking, cement, steel, power and coal industries to pump particle-containing wastewater and waste materials like mine water, reactor waste fluid and paper white water.
  • Municipal Construction Projects
Ideal for drainage facilities in urban sewage plants, municipal pipelines and construction sites, capable of conveying high-solids media including rain-sewage mixed flow and mud slurry.
  • Custom Solutions for Special Environments
It can deliver clean water or slightly corrosive acid-base wastewater. Explosion-proof motors are optional accessories to meet the demands of flammable and explosive working areas.
                                                                                                                                                         

Service Assurance

  • Accurate demand matching

Free on-site demand analysis, customized flow, pressure and piping configuration scheme;

  • Rapid delivery response

Standardized module design, delivery cycle shortened by 30%, emergency project support expedited processing;

  • Flexible warranty policy

1 year warranty for the whole machine, 2 years extended warranty for non-standard customized parts, regular maintenance and fault fast response service.
