The EKATO EPAL impeller was developed to provide optimum suspending and blending characteristics in horizontal vessels. Efficient mixing in these horizontal vessels requires adaptation of the impeller geometry used in standard cylindrical vessels to avoid dead zones that would otherwise develop. In the minerals processing industry, metal leaching using the PAL method (pressure acid leach) – a continuous high-pressure process – that is generally carried out in horizontal vessels which are divided into a number of compartments. Short blend times together with a well-controlled residence time distribution are achieved in the consecutive compartments. These impellers can also improve the mixing efficiency in the few horizontal polymerization reactors still in existence.
EKATO EPAL
Features
Blade geometry specially adapted to horizontal and therefore asymmetrical vessel shapes
As a result, high flow velocities occur primarily in the corners of the vessel
Suspension of solids from the vessel corners at a significantly reduced power input
Short mixing times and quick and efficient mixing of feed flows, maximum chemical conversion and leaching rates in combination with an optimal feeding position

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.
