Submersible Sewage Pumps & Cutter Pumps
Ganquan submersible sewage pumps transfer sewage and drain wastewater from collection pits and pumping stations. Sewage and cutter pump options are selected according to the required flow, head and the type of solids or fibrous material in the water.
Tell us where the wastewater comes from, what it contains and where it needs to go. We can help review suitable pump options and confirm the solids-handling or cutting requirements, installation arrangement and power supply for your project.
Applications for Sewage Pumps & Cutter Pumps
Sewage Transfer
Lift sewage from collection pits or pumping stations to downstream sewers or treatment facilities, with pump selection matched to the required flow and head.
Wastewater with Fibrous Material
Review cutter pump options for wastewater containing fibrous material, with suitability checked against the type and amount of material present.
Construction Site Drainage
Remove collected wastewater from site sumps and drainage pits, with sediment and debris assessed before selecting the pump.
Sewage & Cutter Pump Options
The following Ganquan pump families provide options for sewage transfer and wastewater containing fibrous material. Selection depends on the required flow and head, the characteristics of the wastewater and the installation conditions.
| Series | Pump Type | Selection Focus |
|---|---|---|
| QWB | Submersible sewage pumps | Sewage transfer and drainage, with solids passage checked for the selected model. |
| GNQWB | Submersible cutter pumps | Wastewater containing fibrous and cuttable material, subject to review of the actual contents. |
| ASQWB | Submersible cutter pumps | Sewage and fibrous wastewater duties, with model details and electrical requirements confirmed before quotation. |
Solids-handling and cutting capabilities vary by model. A cutter mechanism is not intended to crush stones or metal objects. Final selection requires the proposed model’s performance curve, solids-handling specifications and confirmation of the power supply and installation arrangement.
Wastewater & Installation Details
Tell us about the wastewater and the installation site so we can review suitable sewage or cutter pump options. The information below helps us assess the pumping duty, solids-handling requirements and installation arrangement.
- Wastewater source: domestic sewage, site drainage or another source, including any known chemicals or oils.
- Solids and fibres: the type, approximate size and amount of material present, including any sand, grit or hard debris.
- Water conditions: temperature, pH and any available wastewater analysis.
- Required duty: flow rate, total head and expected operating hours, if known.
- Discharge route: elevation difference, pipe length, pipe diameter and any required outlet pressure.
- Installation site: collection pit dimensions, minimum and maximum water levels, and access for pump removal and maintenance.
- Power and controls: available voltage, frequency, single-phase or three-phase supply, and any level-control requirements.
- Existing equipment: pump model, nameplate photographs and the reason for replacement, if applicable.
You do not need every detail to start an inquiry. If a value is unknown, leave it open and share any available photographs, drawings or reports. Please identify abrasive or hard debris and any unusual wastewater contents so these can be reviewed before a pump is proposed.
