High Pressure Pipeline Cleaning Machine – 15–25MPa Municipal Sewer Water Jet Cleaning Equipment

High pressure pipeline cleaning, also known as high-pressure water jet cleaning, is widely deployed for municipal sewer pipeline maintenance. Urban sewer pipes act as the underground drainage veins of cities. Sludge, grease, construction debris and biological deposits accumulate on pipe inner walls, reducing flow capacity, triggering blockages, sewage overflow and road collapse risks.

Traditional dredging, chemical cleaning and mechanical scraping are slow, pipe-damaging and polluting. Our 15–25MPa high pressure water jet cleaning machine delivers non-destructive, eco-friendly, high-efficiency cleaning for municipal underground pipe networks.

Our sewer jet cleaning machine pressurizes clean water to 15–25 MPa (custom higher pressure available for heavy-duty blockages) via a high-pressure plunger pump. Pressurized water flows through interchangeable custom nozzles to form high-speed water jets. The jet relies on impact force, shear force and water wedge effect to strip sediment and buildup from pipe walls.

Suspended waste is flushed downstream to inspection wells, then collected by sewage suction equipment for full pipeline cleaning.

This high pressure pipeline cleaning unit fits complex municipal drainage networks, industrial rainwater and sewer lines, aged pipes with dense branch pipelines and heavy silt buildup.

Operators freely adjust working pressure and swap nozzle types according to pipe size and sediment conditions.

Our compact high pressure cleaning machine can enter through inspection wells or small access pits. No large excavation required, low disturbance for residents. Its cleaning speed is 10–40 times faster than manual dredging, without scratching pipe walls to extend pipeline service life.

✅ Economic Benefits

Total cost is only 30–50% of chemical cleaning methods, with much lower labor demand. 50–100m pipe segment cleaning takes only 30–60 minutes. Regular jet cleaning reduces pipe repair & replacement costs, extending pipeline service life by 3–5 years.

✅ Environmental & Social Benefits

Zero chemical additives, no secondary pollution to soil and groundwater. Improves drainage performance and reduces urban flood risk. Case data: Yixing Xinjie Town storm waterlogging duration reduced from 4 hours to 20 minutes; flood-related business losses dropped 82%. It cuts river COD and protects urban water environments.

✅ Non-destructive & Safe

Water-only cleaning, no corrosion or damage to HDPE, concrete, steel sewer pipes.

Our high pressure water jet cleaning machine supports PLC automatic control and can integrate with pipeline inspection robots.
Automated pressure adjustment, visual inspection and intelligent operation will become standard for municipal sewer maintenance.
This green high-pressure jet cleaning solution is the mainstream choice for underground infrastructure maintenance.
