VISCOPROP

The Advanced Hydrofoil Impeller for High Mixing Efficiency

The impeller multitalent with a high mixing efficiency. Thanks to different blade angles (standard versions 25° and 53°) and number of blades, this impeller can be universally used for versatile mixing tasks: Including suspension, blending, heat transfer and dispersion, of low- to highly viscous applications.

The EKATO VISCOPROP is a universal impeller that closes the gap between axial pumping systems for turbulent, low-viscosity regimes and positive displacement mixing systems for laminar, high-viscosity regimes.

Consequently, it is also used in multi-purpose equipment with frequent product changes. The EKATO VISCOPROP is not a purely axial-pumping mixing system. The standard versions have blade angles of 25° and 53°.

A higher blade angle results in an increasingly radial pumping component in additional to the axial component. The VISCOPROP version with the smaller blade angle (25°) is used preferentially for low-viscosity blending and suspending tasks.

The version with the higher blade angle produces a higher local energy input and a higher shear rate in the vicinity of the impeller blades. This enables homogenization of products with higher viscosities or non-Newtonian flow behavior.

What does “Number of sealing faces” mean?

Single-acting mechanical seals
These seals have one sealing surface and only seal in one direction. They are generally simpler in design and are commonly used in applications where pressure is applied from only one side.

Double-acting mechanical seals
These seals have two sealing surfaces and can seal in both directions. They are ideal for applications where pressure may come from both sides or where a higher sealing performance is required.

Triple-acting mechanical seals
These are less common and used in specialized applications that require a more complex sealing setup. They offer additional sealing surfaces or mechanisms to ensure reliable sealing even in highly demanding environments.
