Model: WQ-G
WQ-G grinder submersible pumps add cutting blades ahead of the impeller for fibrous waste. Available from 50mm to 150mm for slaughter-house and seafood-plant sump pits.
| Flow Rate | 10-150m³/h |
|---|---|
| Head | 10-20m |
| Power | 0.75-18.5kW |
| Inlet / Outlet Diameter | 50-150mm |
| Material | Cast Iron,SS304，SS316L |
Standard impellers jam on animal hair, sinew and skin fragments. That’s the problem the WQ-G designation solves, by adding a cutting assembly ahead of the impeller inlet that shreds fibrous material into pieces small enough to pass through cleanly. It’s the same idea at every size, from a small 50mm farm-scale unit up to a 150mm model built for large slaughter-house volume.
| Model | Flow (m³/h) | Head (m) | Power (kW) | Typical scale |
| WQ-G-50-10-10 | 10 | 10 | 0.75 | Small farm |
| WQ-G-65-25-13 | 25 | 13 | 2.2 | Mid-size processing |
| WQ-G-100-100-15 | 100 | 15 | 7.5 | Large seafood plant |
| WQ-G-150-150-20 | 150 | 20 | 18.5 | Large slaughter-house |
Two things apply regardless of size. First, the cutting blades are a wearing part with their own inspection schedule, separate from the mechanical seal; plan for both. Second, the cutting mechanism is built for organic fibre, not rock; hard mineral debris needs screening upstream, or you’ll damage blades rather than shred anything useful.
