Our submersible sewage pump is an integrated pump-motor machine made by AOTE TIANJIN PUMP CO., LTD.. It is built to work fully submerged in sewage pits, septic tanks and waste water pools. It uses high-strength cast iron or stainless steel shell to stand dirty, corrosive and muddy water. It can carry waste water with small solid waste, cloth fibers and mud particles, and it avoids the easy-clog problem of ordinary water pumps.
1. Fully submerged operation: The whole pump works under water, with low running noise and natural water cooling for the motor.
2. Anti-clog design: Wide-channel or cutting impeller passes solid waste smoothly, and long fibers will not wrap the rotating parts.
3. Double waterproof mechanical seal: IP68 waterproof grade stops sewage from leaking into the motor to avoid burnout.
4. Automatic water level control: Match float switch to start or stop the pump by the height of sewage, no manual watch needed.
5. Anti-overheat & anti-dry protection: Built-in temperature sensor cuts power if the motor runs without water or gets too hot.
Residential areas: Septic tank drainage, basement flood water removal, domestic waste water lifting.
Municipal projects: City sewage stations, wastewater treatment plants, rainwater discharge for underground parking lots.
Industrial sites: Factory production waste water, mine muddy water, construction site flood dewatering.
Agriculture & breeding: Livestock farm manure water, farmland flood drainage, pond sludge transfer.
Commercial buildings: Shopping mall underground drainage, hotel sewage lifting, public toilet waste water treatment.
1. Submersible motor: Sealed oil-filled motor with F-grade insulation, stable power output and long service life.
2. Mechanical seal set: Double-layer hard alloy seal prevents sewage from entering the motor chamber.
3. Impeller: Wide flow channel / cutting impeller for smooth passing of solid waste.
4. Pump casing: Thick cast iron shell, wear-resistant and anti-corrosion.
5. Oil chamber: Stores lubricating oil to protect the seal and reduce friction.
6. Power cable: Waterproof rubber cable, resistant to oil and corrosion for long underwater use.
7. Float switch (optional): Automatic sensor to control pump start and stop according to water level.
1. All-in-one compact design: No separate pump house required, easy to put into sewage pits and save installation space.
2. Simple installation and maintenance: Equipped with guide rail base, users can lift the pump out quickly without entering the sewage pit for cleaning or repair.
3. Energy-saving motor: High-efficiency IE3 motor cuts power consumption during long-time continuous work, lowering users’ daily operation cost.
4. Strong adaptability: Multiple power, flow and head models for different working conditions; stainless steel models are available for acid and alkali corrosive sewage.
5. Stable running performance: Strict dynamic balance test for impellers reduces vibration and noise, and parts wear slower to extend pump service life.
6. Customizable solution support: We can adjust pump parameters, material and extra protection devices to match clients’ special project needs, providing one-stop customized pumping solutions for diverse industrial and civil projects.
1. Raw material inspection: All cast iron, stainless steel and motor copper wire pass strict material tests before production, unqualified materials are rejected directly.
2. Production process tracking: Every production step has special quality inspectors to check size, welding and assembly quality, and each pump has a unique serial number for full record tracking.
3. Full water tightness test: Each finished pump is put into water for 24-hour leakage test to make sure no sewage can enter the motor.
4. Performance test: All pumps run under standard load to test flow, head, power and noise, only pumps that meet all data standards can be packed and shipped.
5. Aging test: Randomly select finished pumps for 100-hour continuous running aging test to check long-time operation stability.
6. Pre-shipment recheck: Before delivery, inspectors check pump appearance, cable, accessories and packing once again to avoid missing parts or damaged goods.
A1: No. The motor of the submersible sewage pump relies on surrounding water for cooling. Long-time dry running will make the motor overheat and burn out. Our pump has built-in overheat protection to cut power automatically in this case.
A2: Standard models can pass solid waste with diameter up to 50 mm. Cutting type impeller models can cut long cloth, plastic strips and soft fibers into small pieces to prevent wrapping blockage.
A3: No. Just put the pump into the sewage pit, connect the discharge pipe and power cable. If you choose the guide rail base, you can lift the pump out easily for later cleaning without entering the dirty pit.
A4: With regular simple maintenance, the pump can work stably for 5–10 years. Key wearing parts like mechanical seals can be replaced separately to extend the whole pump’s service life.
A5: Yes. We provide stainless steel pump body and impeller models for corrosive waste water. You just need to tell us the PH value of your sewage before ordering.
A6: No. Since the whole pump works fully submerged under water, water blocks most running noise. It is much quieter than ground centrifugal pumps.
AOTE TIANJIN PUMP CO., LTD. focuses on submersible sewage pump and all kinds of water pump production for many years, and we fully understand different clients’ working condition demands from all over the world.
From raw material selection to finished pump delivery, every link has strict inspection rules, so every pump you receive has stable and reliable performance.
We have dozens of pump models with different power, flow and lift. If standard models cannot fit your project, our technical team can adjust pump structure and parameters to meet your special requirements.
Our pumps use high-efficiency energy-saving motors to cut daily power bills, and the wear-resistant parts reduce replacement frequency to save your later maintenance cost.
We provide clear operation and maintenance manuals for all pumps. If you meet any technical or quality problems after receiving goods, our professional after-sales team will reply and give solutions quickly.
All pumps are packed with shock-proof wooden cases to avoid damage during long-distance sea or land transportation. We support flexible delivery arrangements and fast shipment to match your project schedule and procurement cycle.
