Sewage Pump For Septic Tank

The septic tank sewage pump is a submersible sewage pump specially designed for the lifting scenarios of septic tanks/triple-segment tanks in households, villas, residential areas, rural toilet renovations, campsites, and mobile toilets. Its physical characteristics are as follows: mainly consisting of toilet paper, excrement, and flocculent substances, with a small amount of food residues, wet wipe debris, occasionally bottle caps/plastic pieces/wet hard objects. The pH is slightly alkaline and close to neutrality. It also contains corrosive gases such as H₂S (when aeration is poor).

(Blade-cutting type) Cutting process: The rotating cutter disc at the front of the machine + the fixed cutter base first cuts the toilet paper balls, wet wipes fragments, and clumps into short segments, and then feeds them into the impeller.
(Non-cutting large-channel type) Vortex/double-channel: The paper clumps "slide through without getting tangled" due to the geometric shape of the impeller. - The vortex-type impeller does not directly touch the fiber clusters and relies on the vortex to carry them out. It has extremely high tolerance for paper clumps but has slightly lower efficiency than the cutting type.
Impeller discharge: The chopped or flowing slurry enters the single/double-channel or vortex impeller → volute → outlet flange → discharged to the second/third compartment of the septic tank or the external pipeline network.
Submerged operation: Motor F class/IP68, oil chamber + double mechanical seals + oil-water probe; The gas corrosion in the septic tank is resisted by O-ring material and the cable sheath.

Full copper motor overheat protection
Stable and reliable full copper core motor, with smooth power output, low temperature rise, long lifespan, and less prone to overheating
Mechanical seal oil seal, high-precision rotor, silent bearing
High-precision components, oil-proof and moisture-proof, long lifespan
Cutting blades: High-chrome alloy cutting blades, wear-resistant and corrosion-resistant
Precision casting body, thick material, long lifespan, surface spray coating, beautiful appearance
Water outlet: Convenient for pipeline connection, easy to use
Low water level inlet: The inlet is equipped with a mesh hole to prevent large particles from entering the pump body, causing the pump to get stuck or burn out

Single-family / villa septic tank lifting: Each household has its own septic tank or several households are connected in series. The pump lifts the effluent to the municipal pipeline or a small artificial wetland/AO device. The flow rate is 0.5 - 3 m³/h, and the lift height is 8 - 15 m. This is the most typical.
Centralized lifting for rural toilet renovation (three-stage septic tank): The effluent from dozens of households in a village is collected in one lifting well, and then sent to the village-level treatment or pipeline. The flow rate is 5 - 20 m³/h, and it uses a swirl flow / double channel + anti-corrosion + FKM multi-component.
Mobile toilets in military camps / scenic areas: Temporary or semi-fixed toilets. The pump is small, and the entire unit can be lifted away. It is equipped with a control box + float ball for plug-and-play operation.
Cluster of small inns ： Several inns share one septic tank. The pump lifts the effluent to the ecological treatment tank. The flow rate is 3 - 10 m³/h.
