Understanding the Core: Technical Parameters of Non Clog Sewage Pumps

A non clog sewage pump is engineered for the unimpeded passage of large solids and fibrous materials without blockages, a critical feature distinguishing it from conventional pumps. Key technical parameters define its capabilities and suitability for various applications:

• Flow Rate (Q): Measured in m³/h or GPM, indicating the volume of fluid the pump can move per unit of time. For sewage applications, this can range from a few cubic meters per hour for small commercial buildings to thousands for municipal lift stations.
• Total Head (H): Measured in meters or feet, representing the vertical distance the pump can lift the fluid plus friction losses in the piping system. Sewage applications often require moderate to high heads to overcome elevation differences and pipe resistance.
• Motor Power (P): Measured in kW or HP, the electrical power required to drive the pump. This is directly related to the required flow rate and head. CY Pump offers a range from 0.75 kW to 300 kW to meet diverse operational demands.
• Solids Handling Capability: A critical parameter, specifying the maximum spherical solid size (in mm or inches) that the pump can pass without clogging. For example, a typical submersible non-clog sewage pump might handle solids up to 100mm.
• Impeller Type: The heart of the non-clog design. Common types include:
  • Vortex Impeller: Creates a swirling action in the pump casing, allowing solids to pass through without touching the impeller, ideal for stringy and abrasive media.
  • Channel Impeller (Single/Multi-channel): Features open passages, allowing larger solids to pass while still providing efficient pumping action. Single-channel is best for very large solids, multi-channel for better hydraulic efficiency with smaller solids.
  • Cutter/Grinder Impeller: Equipped with sharp cutting edges at the inlet to macerate solids before they enter the pump, suitable for highly fibrous materials.
• Material Construction: The choice of material is crucial for durability and corrosion resistance. Common materials include:
  • Cast Iron (HT200, HT250): Standard for general sewage applications due to its cost-effectiveness and good wear resistance.
  • Stainless Steel (SS304, SS316, Duplex SS): Essential for corrosive or abrasive media, offering superior resistance to chemical attack and pitting. Duplex stainless steel (e.g., SAF 2205) provides even higher strength and corrosion resistance.
  • High-Chrome Alloy: Utilized for extremely abrasive applications, offering exceptional wear resistance.
• Sealing System: Typically double mechanical seals (e.g., silicon carbide/silicon carbide) in an oil chamber for reliable sealing and prevention of motor ingress.
• Installation Type: Primarily submersible, but also available as dry-pit or pipe type non clogging sewage pump configurations.

This design minimizes contact between the solids and the impeller, preventing blockages.
2. What materials are commonly used for non clog sewage pumpes, and why?
   Common materials include Cast Iron (HT200/HT250) for general sewage due to its durability and cost-effectiveness; Stainless Steel (SS304/SS316) for corrosion resistance in mildly acidic/alkaline or slightly corrosive applications; and Duplex Stainless Steel (e.g., SAF 2205) for superior corrosion and abrasion resistance in harsh chemical or high-salinity environments. High-Chrome Cast Iron is used for highly abrasive slurries.
3. How is solids handling capacity measured for a submersible non-clog sewage pump?
   Solids handling capacity is typically measured by the maximum spherical solid diameter (in millimeters or inches) that the pump can pass without clogging. This is determined by the smallest passage dimension through the impeller and volute casing. For example, a pump rated for 75mm solids can pass a sphere of that diameter.
4. What are the key benefits of using a submersible non-clog sewage pump over a conventional pump?
   Key benefits include significantly reduced risk of clogging, leading to less downtime and lower maintenance costs; ability to handle highly contaminated media with large solids and fibrous materials; longer operational life in harsh environments due to robust construction; and often, easier installation in confined spaces below grade.
