When to Choose a Jet Pump
- No moving parts required
- Corrosive or abrasive fluids
- Vacuum or suction lift needed
- Explosion-proof environment
- Minimal maintenance budget
- Handling solids or slurries
- Low initial cost is a priority
When to Choose a Centrifugal Pump
- High flow rates required
- Clean, low-viscosity fluids
- Precise flow control needed
- Continuous high-volume transfer
- Efficiency is the top priority
When to Choose a Mechanical Agitator
- Very high viscosity fluids
- Gentle mixing without pumping
- Large open-top tanks
- Batch processing
- No motive fluid available
