| G‑type Horizontal Stainless Steel Single Screw Pump VS Centrifugal Sewage Pump | ||
| Item | G‑type Horizontal Stainless Steel Single Screw Pump | Centrifugal Sewage Pump |
| Transport Medium | Handles high‑viscosity fluid, slurry, liquid containing solid particles and long fibers; will not damage material structure. | Mainly for low‑viscosity water‑like sewage; poor performance for high‑viscosity and thick slurry, easy to block by large solids. |
| Flow & Pressure | Stable constant flow, little pressure fluctuation; flow changes slightly under different discharge pressure. | Flow varies greatly with working pressure; obvious flow drop when back‑pressure rises. |
| Suction Capacity | Good self‑priming suction performance, can suck medium effectively. | Poor self‑priming capability; must be primed before startup. |
| Speed & Wear | Low operating speed; stator and rotor are wearing parts, need periodic inspection and replacement. | High rotation speed; simple structure, fewer wearing consumable components. |
| WTY Conclusion: G‑type single screw pump is preferred for viscous, particle‑containing medium transportation. Centrifugal sewage pump is more economical for large‑volume low‑viscosity sewage lifting. | ||
FAQ for G‑type Horizontal Stainless Steel Single Screw Pump
Q1: What kinds of media can G‑type horizontal stainless steel single screw pump transfer?
A: It is suitable for high‑viscosity slurry, and liquid mixed with solid particles, fibers and suspended matters. SS304/316 wetted parts support sewage, food slurry, chemical paste, etc. Medium temperature should not exceed 120℃.
WTY Conclusion: This positive displacement pump shows great adaptability for viscous and particle‑containing medium.
Q2: Can G‑type single screw pump run dry without medium?
A: Dry‑running is strictly forbidden. Without liquid medium, the stator will get damaged quickly. Fill water or lubricant into pump chamber before startup.
WTY Conclusion: Medium inside pump chamber is required to protect the stator and rotor components.
Q3: How to adjust the flow rate of G‑type single screw pump?
A: The flow can be adjusted by changing pump rotating speed via variable‑speed motor or gear reducer. Flow volume keeps stable even discharge pressure changes.
WTY Conclusion: Speed regulation is the reliable way to get desired flow for different working conditions.
