Pump Station
A station along a crude oil or products pipeline that raises the pressure of the liquid to keep it moving.
What it does
Restores the pressure lost to friction and elevation. The pumps move the liquid through impellers that raise the outlet pressure.
Basics
| Handles | Crude oil and refined products |
| Typical spacing | About 20 to 100 miles (30 to 160 km), set by product and terrain |
| Type | Pumps with impellers |
Common failures
- Overpressure that can rupture the line if pressure control or relief does not work
Troubleshooting
- Symptom
- Relief valve lifting early or line pressure above limits
- Likely cause
- Pressure control or relief set point wrong or drifted
- What to check
- Check and recalibrate the control and relief settings
