Component Specifications

Definition
Tank baffles are engineered internal partitions installed within coolant reservoirs or pump tanks to control fluid dynamics. They function by disrupting rotational flow patterns, preventing vortex formation that can lead to pump cavitation, air entrainment, and uneven temperature distribution. These components are strategically positioned to create controlled turbulence, ensuring proper mixing and preventing sedimentation of contaminants in industrial cooling systems.
Working Principle
Tank baffles operate on fluid dynamics principles by creating controlled resistance to rotational flow. When fluid circulates within a reservoir, centrifugal forces naturally create vortex patterns. Baffles interrupt these patterns by presenting physical barriers that redirect flow, converting rotational energy into turbulent mixing energy. This prevents stratification, maintains homogeneous fluid properties, and ensures consistent pump inlet conditions.
Materials
Stainless steel (AISI 304/316), galvanized steel, polypropylene, PVC, or fiberglass-reinforced plastics. Material selection depends on coolant chemistry (pH, additives), temperature range (-20°C to 120°C), and corrosion resistance requirements. Thickness typically ranges from 1.5mm to 6mm.
Technical Parameters
  • Height 70-95% of tank height
  • Mounting Welded, bolted, or clamped
  • Clearance 10-20mm from tank walls
  • Thickness 1.5-6mm
  • Surface Finish Ra 3.2μm or smoother
  • Number per Tank 2-8 depending on diameter
Standards
ISO 2858, DIN 24255, ASME B31.3

Frequently Asked Questions

How do tank baffles improve pump performance?

Baffles prevent vortex formation that causes pump cavitation, reducing noise, vibration, and premature wear while maintaining consistent flow rates.

What maintenance do tank baffles require?

Regular inspection for corrosion, fouling, or structural damage. Cleaning during system maintenance to remove sediment buildup that reduces effectiveness.

Can baffles be retrofitted to existing tanks?

Yes, with proper engineering assessment. Considerations include tank material, existing welds, and access limitations for installation.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
