Product Description

The Cutting Submersible Sewage Pump from AOTE PUMP adopt a well-matched combination of dry-type motor and pump body. They are mainly used for conveying domestic wastewater, sewage, human excreta, as well as non-corrosive media containing suspended solids like short fibers, paper scraps, wood chips, starch, sediment and mineral particles. The temperature of the pumped liquid shall not exceed 40℃, its density shall not be higher than 1200kg/m³, and the pH value shall range from 5 to 9.

Submersible Sewage Pump advantages

Cutting Submersible Sewage Pump are equipped with double mechanical seals and rotary impellers made of stainless steel, these pumps deliver outstanding wear resistance, and are free from clogging and winding. They also boast the advantages of compact structure, small size and easy handling.

Application Scope

• Construction sites, foundation works, municipal facilities and water plants.
• Wastewater drainage for basements, civil air defense tunnels, subways and other underground areas of high-rise buildings.
• Sewage treatment and circulating water transportation for small and medium-sized enterprises.
• Slurry delivery for factories and mines including food, paper making, brewing, iron & non-ferrous metal, leather making, textile, pharmaceutical and cement industries.
• Water pumping, pond cleaning and oxygenation for chicken farms, pig farms, other breeding farms and fish ponds; pumping of human and livestock manure from septic tanks and similar scenarios.

What our cutting system actually does

Cuts ordinary domestic waste (wipes, hair, cotton rags) into particles <15mm.

Cuts agricultural waste (rice straw, hemp rope, plastic film) with a 2‑stage shear mechanism: first coarse cut, then fine shredding.

For heavy-duty applications (e.g., slaughterhouse waste with bone fragments), we recommend our duplex stainless steel impeller option – not standard, but available.

When NOT to use this pump

Liquid temperature >40℃ (for higher temp, ask for our high-temp version)

pH <5 or >9 (acidic or alkaline chemical waste)

Liquid containing oils or greases >5% – oil will degrade mechanical seal rubber parts

Continuous operation under dry running – our Cutting Submersible Sewage Pump requires submerged condition for cooling

If your working condition falls outside these ranges, contact our engineers for a tailored selection – we regularly supply modified versions for special orders.

FAQ

Q1: Can it handle plastic bags without stopping?

A: Yes, it can cut them. However, if your wastewater contains a large volume of plastic film, we suggest checking the inlet strainer every 50 operating hours. In a textile mill application, we observed that heavy plastic accumulation reduced flow rate but did not burn out the motor.

Q2: How do I choose between cast iron and SS316L?

A: Cast iron is sufficient for municipal sewage and farm waste. SS316L is only needed when the water contains chlorides (e.g., seawater intrusion) or acidic condensate. You can send us a water test report – we will advise free of charge.

Q3: What is the lead time? Do you provide installation support?

A: Standard models: 15–20 working days. We supply an English manual and dimension drawing. We can also arrange a free video call for first‑time installation guidance.
