Key Notes on Pressure Drop for PVC / CPVC Static Mixers

  • PVC and CPVC Static Mixers typically have low to moderate pressure drop — suitable for most water treatment and mild chemical applications.
  • Pressure drop increases with the square of the flow rate and rises significantly with higher viscosity fluids.
  • CPVC can handle higher temperatures than PVC (up to 190°F / 88°C), but both materials have similar pressure drop characteristics.
  • Helical element designs are most common in PVC/CPVC mixers, offering a good balance between mixing performance and pressure loss.
  • Typical design target is 5 – 18 psi to achieve thorough mixing without excessive pumping costs.
  • For slurry or higher-viscosity services, pressure drop can increase substantially — consult manufacturer for exact calculations.
  • Always respect the pressure and temperature ratings of PVC (lower) versus CPVC (higher).

PVC and CPVC Static Mixers are widely used in water treatment, chemical dosing, and mild corrosive services due to their excellent corrosion resistance and low cost.
The pressure drop curve helps engineers properly size feed pumps and ensure the mixer delivers the required mixing uniformity without overloading the system.

For accurate pressure drop data tailored to your flow rate, fluid viscosity, temperature, and specific PVC/CPVC mixer design, consult the manufacturer for a custom performance curve.

Installation
