Aquaculture Pump Manufacturers — Buyer's Knowledge Page
Pumps are the single biggest energy line-item in commercial aquaculture. A well-selected axial or propeller pump can cut RAS pumping energy in half versus a poorly-selected centrifugal. Do the head calculation first.
FishMatch Group is supplier-neutral. This page is educational content for buyers — not legal advice, not a supplier ranking.
Typical applications
- Sea water and fresh water intake
- RAS circulation (low head, high flow)
- Effluent transfer and irrigation reuse
- Air-lift for sludge and process water
Project sizes
- Small: <500 m³/h
- Mid: 500–5,000 m³/h
- Large: 5,000–100,000+ m³/h
Selection criteria
- Duty point on the actual pump curve (not marketing curve)
- Efficiency at duty and part-load
- Corrosion resistance (marine-grade for sea water)
- NPSH available vs required
- VFD compatibility for turndown
Questions buyers should ask
- What is the guaranteed efficiency at my duty point?
- What is the material spec and warranty against corrosion?
- What is the total 10-year energy cost estimate?
Common procurement mistakes
- Selecting on flow rate alone, ignoring head losses
- Missing NPSH calculation on suction-lift installations
- Skipping VFDs then paying 30–50% more in energy for the plant life
RFQ recommendations
- Publish real system curve (H vs Q) with the RFQ
- Tender by kWh/m³ delivered at duty
