The sealing system is internal to the product, for which it is necessary to remove the agitator from the tank in order to replace the seal.

Every side entry mixer of the AL series Grec is made by a high strength aluminum lantern with thrust bearing and by a sleeve coupling that acts as a link between the motor shaft and the mixing shaft, while the process connection is made using standard DIN flange (or other, according to the customer requirements).

.
Versatile and inexpensive, the AL series agitators Grec are equipped with a mechanical seal soaking in the product, as well as a flushing and outlet connection  for sparkling products.

Also, the side mixers of the AL series are available in ATEX version for zones 1 and 2 and have new high efficiency impellers .

The side mixers of the AL series Grec are particularly suited for :

– Avoid sedimentation of solids

– Homogenize different currents of products

– Disperse additives such as bentonite, CO₂, SO₂ and  sugar

– Increase the fermentation rate or the coefficient of heat exchange

The base series, without suffixes, is used for wine only, while the series with -W suffix, for all other applications, including sparkling wines. In the traditional version, the engine adds a lantern with thrust bearing, to prolong the life of the seal.

For smaller sizes, you can use a more modern and economical version, the AL0 series, with oversized shaft but without lantern.

Grec Srl specializes in the selection, design and construction of industrial agitators for liquids, ensuring reliable, economic and personalized solutions, according to the customer’s requirements.

Grec Srl aims to determine the most functional combination between impeller, diameter, speed of rotation and positioning inside the tanks, by selecting the most appropriate constructive solutions.

The Grec agitators have high versatility, and are able to operate in many applications, like:

– Storage tanks for the food industry, chemical and oil

– Processes of water treatment

– Solids mixing and suspension processes in the mining, ceramics and general industry

– Preparation of chemical products through processes of mixing, dispersion and dissolution

– High viscosity applications with the use of axial or radial impellers

In the standard version, when the liquid to be stirred does not damage the seal, it is internal to the process and requires the extraction of the mixer for its replacement.
If the model with no suffix, the seal is made of graphite/SS.

The side agitators of the ALC series Grec consist of helical-bevel geared motor with high reliability, bell and cartridge mechanical seal. These agitators are also available with spacer coupling between gearbox and sealing, a shut off system, larger flange with angled nozzle, depending on the client needs.

The range of ALC side agitators is the best choice for storage applications or simple mixing in large diameter tanks .
The bevel gear unit allows to maintain the machine compact, with the engine at the top.
The agitator shaft is directly inserted into the gearbox and secured with a screw.
There are different constructive options for the sealing system, including the shut off, or the static seal system that allows to replace the mechanical seal without having to empty the tank.
This series is also available in versions for environment ATEX Zone 1 and Zone 2.
