Pressure Pumps
3 companies listed
Pressure pumps deliver the high-pressure water stream that loosens soil during hydrovac excavation. Pump type, flow rate, and pressure range determine digging speed, water consumption, and the ability to cut through different soil conditions.
What to Look For
- PSI and GPM ratings appropriate for your soil conditions and excavation depth
- Triplex versus other pump designs for reliability and serviceability
- Cold weather capability including winterization and freeze protection
- Ease of field service and parts availability from the manufacturer

Frequently Asked Questions
What PSI is needed for hydrovac excavation?
Most hydrovac work uses 1,000-3,000 PSI. Clay and compacted soils need higher pressure; sandy or loose material needs less. Operators adjust pressure to avoid damaging utilities.
How long do hydrovac pressure pumps last?
Triplex pumps typically last 3,000-6,000 hours between overhauls. Regular packing and valve replacement extends pump life significantly.
