Product Overview
JYWQ / JBWQ / JPWQ Submersible Sewage Pump with Automatic Agitator is a submersible non-clog centrifugal pump designed for sewage, sludge, and sediment-laden wastewater handling.
It solves bottom sediment accumulation, sludge settling, and blockage risks in high-solid wastewater systems.
It is applied in sewage pits, sedimentation tanks, industrial slurry drainage systems, and municipal wastewater installations.
Model Designation
Applications
• Wastewater sumps with sludge deposition
• Sedimentation tanks requiring continuous agitation
• Industrial slurry discharge pits
• Mining and construction slurry drainage
• Municipal sewage lift stations
• Wastewater equalization tanks with solid suspension requirement
Engineering Advantages
• Integrated automatic agitator structure increases bottom shear force, preventing sludge deposition and improving solid suspension.
• Non-clog impeller hydraulic design allows stable passage of suspended solids.
• Submersible motor integration eliminates shaft alignment requirements and reduces installation footprint.
• Mechanical seal chamber with double sealing arrangement improves reliability under abrasive conditions.
• Pump and agitator operate simultaneously to maintain hydraulic efficiency in sediment-laden environments.

H2 How to Select a Pump Model
• Determine required flow rate and head based on sump volume and discharge pipeline layout.
• Evaluate solid concentration and particle characteristics to confirm impeller type.
• Verify submergence depth and motor cooling conditions.
• Confirm power supply voltage and protection configuration.
• For high sludge environments, ensure agitator torque meets sediment lifting requirement.
H2 Engineering Notes
• Not suitable for explosive or highly corrosive chemical liquids without material modification.
• Continuous dry running is prohibited.
• Proper cable sealing is required for deep installation.
• Abrasive media will accelerate impeller wear; inspection interval should be adjusted accordingly.
H2 Compliance & Quality Assurance
• Factory hydraulic performance testing
• Insulation resistance and electrical safety testing
• Mechanical seal leakage verification
• Dynamic balance inspection of rotating components
• Material traceability documentation
• Optional third-party inspection available
H2 Safety Notice
• Do not operate under dry-running condition
• Ensure pump is fully submerged before startup
• Disconnect power before maintenance
• Do not exceed rated discharge pressure
H2 OEM & Customization
This pump series supports engineered configuration and duty-based matching. Technical adjustments can be made according to system requirements and installation conditions.
Available options include:
• Motor voltage & frequency
• Mechanical seal type and configuration
• Wetted parts material selection
• Surface coating and corrosion protection
Configuration is determined based on duty point and project specifications.
H2 FAQs
Q: Can the pump operate under VFD control?
A: Yes, within rated hydraulic and cooling limits.
Q: What is the allowable solid particle size?
A: Determined by impeller passage size and model specification.
Q: What sealing options are available?
A: Double mechanical seal configuration is standard; special materials available upon request.
Q: What is the maximum allowable liquid temperature?
A: Standard configuration supports ≤ 40°C.
Q: Is continuous operation permitted?
A: Yes, provided the pump remains fully submerged.
Q: What standards does the pump comply with?
A: Manufactured according to applicable industrial centrifugal pump and electrical safety standards.
Q: How is sediment lifting ensured?
A: The integrated agitator generates bottom turbulence to suspend settled sludge.
