Pipe diameter for pumping puree

Viscous products are pumped slower. Set your own flow velocity and the calculator selects the diameter for puree or paste.

Frequently asked questions

What velocity for thick puree?
Typically 0.3–0.8 m/s depending on viscosity and pump; higher velocities cause large pressure losses.

The calculations are approximate: they help to assess the process and compare options, but do not replace a process design and trials on a specific raw material. This section is for reference only and contains no commercial offers.
