A reliable High Pressure Water Assembly is essential for safe and efficient hydro excavation. Designed for vacuum excavators and hydrovacs, our pressure water assemblies deliver the water flow and pressure required to break up soil while minimising the risk of damaging underground services.
At No Dig Equipment, we manufacture and supply heavy-duty high pressure water assemblies and replacement parts for vacuum excavation systems used throughout Australia. Built for demanding civil, mining and utility applications, our components are engineered for long service life, dependable performance and easy maintenance.
Whether you’re replacing worn components or upgrading your existing hydro excavation system, our water pressure assemblies are designed to keep your equipment operating at peak performance.
The 1814B High Pressure Water Pump has 18mm ceramic pistons that can produce a 3500 PSI at flows of 15 liters per minute. It is designed to run at a speed of 1450 rpm on 24 mm shaft. The pump is fitted with high quality Japanese bearings, Parker seals, thermal relief valve and a pressure relief valve.
Shipping weight of this unit is 9.5 kilograms. This pump is powered by our Kohler Diesel engines and used for large capacity Vacuum Units like VM850, VM2000, VM3000, and VM4500.
The 1807B High Pressure Water Pump has 18mm ceramic pistons that can produce a 2500 PSI at water flows of 10 liters per minute. This pump is designed to run at a speed of 2800 rpm. It is driven through a standard on 24 mm shaft and has high quality Japanese bearings, Parker seals, thermal relief valve, pressure relief valve fitted as standard.
Shipping weight of this unit is 9.5 kilograms. This pump is powered by either Petrol or Diesel Engine and is mainly installed in our general purpose VM400 vacuum machine.
We offer a range of pot holing High Pressure Water Assembly parts to suit different operating environments and excavation requirements. Each option is designed to maximise excavation efficiency while helping operators safely expose underground services.
Our electromagnetic electric clutch allows operators to switch between vacuum-only or simultaneous vacuum and water operation, improving efficiency and reducing operating costs.

A high-quality water pressure system is critical to the performance of every hydro excavation machine. Our assemblies are built using quality components to deliver consistent water pressure, reliable operation and reduced downtime.
✔ Designed for hydro excavation and non-destructive digging (NDD)
✔ Safe excavation around underground utilities
✔ Reliable high-pressure water delivery
✔ Suitable for vacuum excavators and hydrovacs
✔ Built for professional civil, mining and utility contractors
✔ Genuine replacement parts and assemblies available
A high pressure water assembly is the system responsible for delivering pressurised water to the excavation wand during hydro excavation. The pressurised water loosens soil, while the vacuum system immediately removes the resulting slurry.
This combination allows operators to excavate accurately around underground infrastructure while significantly reducing the risk of damaging buried assets compared to traditional mechanical excavation methods.
With over 25 years of experience supplying trenchless technology equipment across Australia, No Dig Equipment is trusted by contractors working in civil construction, mining, utilities and infrastructure.
When you choose No Dig Equipment, you benefit from:
Our pressure water assemblies are suitable for a wide range of hydro excavation applications, including:
Traditional excavation methods such as excavators and trenchers can easily damage buried infrastructure when service locations are unknown.
Using a high pressure water assembly allows operators to safely expose:
The controlled water pressure softens and removes soil without the aggressive impact of mechanical digging equipment, making hydro excavation one of the safest excavation methods available.
No Dig Equipment supplies high-quality pressure water assemblies manufactured to withstand the harsh conditions encountered on Australian worksites.
Our assemblies are designed to provide:
Because many of our vacuum excavator parts are manufactured in-house or sourced locally, replacement parts are readily available throughout Australia, helping minimise downtime and keep your projects moving.
Our high pressure water assemblies are designed to suit No Dig Equipment’s range of Australian-made vacuum excavation systems, including:
If you’re unsure which pressure water assembly or replacement part suits your machine, our experienced team can recommend the best solution for your equipment.
A high pressure water assembly is the component of a hydro excavation system that delivers pressurised water to the excavation wand. It breaks up soil so the vacuum system can safely remove it during non-destructive digging.
Water pressure assemblies are used for hydro excavation, utility locating, potholing, trenching and safely exposing underground infrastructure without damaging buried services.
High-pressure water loosens compacted soil while reducing the risk of striking underground pipes, electrical cables and telecommunications infrastructure. Combined with powerful vacuum suction, it provides a safe and efficient excavation method.
