FAQS

A centrifugal pump is a rotodynamic (kinetic) pump that uses a rotating impeller to add energy to a fluid, primarily by increasing its velocity (kinetic energy) and then converting that into pressure energy. Fluid enters along the impeller axis and is flung outward radially.

Titanium naturally forms a stable, self-healing passive oxide layer that provides outstanding corrosion resistance. It resists most organic and inorganic acids, alkalis, salts, chlorides, and seawater—even at elevated temperatures or when the surface is scratched or abraded. Unlike stainless steel (which relies on a surface layer that can be damaged), titanium’s resistance is inherent throughout the material. Titanium alloys also offer high strength-to-weight ratio, excellent elasticity (better shock and cavitation resistance), and low density (about 4.51 g/cm³, 45% lighter than steel).

  • Single-stage: One impeller; suited for moderate head and high flow.
  • Multi-stage: Multiple impellers in series; for high-pressure applications (e.g., boiler feed).
  • End-suction: Common, compact design for general use.
  • Submersible: Pump and motor submerged in the fluid.
  • Horizontal or vertical configurations, including chopper pumps for solids-laden fluids.
  • Impeller: The rotating element that imparts energy to the fluid.
  • Casing (volute or diffuser): Collects and directs the flow while converting velocity to pressure.
  • Shaft: Connects the impeller to the driver (usually an electric motor).
  • Bearings and seals: Support the shaft and prevent leaks (mechanical seals or packing are common).
  • Suction and discharge nozzles.
  • Superior corrosion and erosion resistance in chloride-rich or acidic environments.
  • Longer service life (often 2–10× or more than stainless steel or cast iron in aggressive media).
  • Lighter weight, easier installation and maintenance.
  • Better resistance to cavitation, abrasion (especially with alloyed titanium), and thermal shock.
  • Non-magnetic and biologically inert (useful in some pharma or marine uses). Titanium pumps outperform duplex stainless steel in higher temperatures and higher chloride concentrations, while duplex SS may be more cost-effective in milder conditions.

They are widely used in:

  • Chemical and chlor-alkali processing
  • Salt production and brine handling
  • Seawater desalination, cooling systems, and marine/offshore platforms
  • Petrochemical refineries
  • Slurry pumping with acidic or abrasive media
  • High-temperature corrosive fluid transfer Typical designs are single-stage, single-suction (cantilever or centerline-supported OH2 for high temps).

Standard titanium centrifugal pumps operate from approximately –80°C to +300°C (depending on alloy and design) and handle pressures up to 26 bar or higher. They maintain performance in high-temperature, high-chloride, or extreme pH environments where other materials degrade rapidly.

Titanium alloys provide good abrasion resistance (improved further with alloying elements) and high elasticity, reducing cracking from cavitation or shock loads. They are excellent for highly acidic/abrasive slurries where stainless steel impellers and casings wear out quickly. They are less ideal for very high-viscosity fluids (centrifugal pumps in general have limitations here).

Common choices include:

  • Pure titanium grades (TA2) for general corrosion resistance.
  • Alloys like TA9/TA10 or Ti-6Al-4V for added strength or specific chemical resistance. Consult the pump manufacturer with your fluid chemistry, temperature, pressure, flow rate, and solids content. They can recommend the optimal grade and pump configuration (e.g., single-stage vs. multi-stage).
