Pump power for puree of 1080 kg/m³ density

Product density can be entered manually; for viscous media pump efficiency is lower so a larger margin is used.

Frequently asked questions

Why is pump efficiency lower for puree?
High viscosity increases internal friction and centrifugal pumps lose efficiency; positive displacement pumps are used for thick masses.

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.
