BG 500

Agitator BG 500

The PAULMICHEL-Agitator BG500 has an infinitely variable and easy-to-use hydraulic adjustment system. Due to this, an optimal positioning of the agitator in relation to the substrate of the tank is possible, even if the level in the secondary fermentation tanks or gas-tight final storage tanks changes. For use in high-pressure tanks in particular, this adjustment device is second to none.

With an agitator-blade diameter of 600 – 840 mm, the BG500 provides a powerful but nevertheless low-noise transmission by means of a toothed geared belt drive. As an option, the agitator can be supplied with a universal joint shaft drive-through for use with tractor drive.

The agitator BG500 is used to mechanically and powerfully support the homogenisation process in fermenters, mainly in the solid entry area. Due to the use of a high-quality sealing unit on the mounting plate of the tank, it is possible to operate the agitator in secondary fermentation tanks at various heights. The sealing can also be monitored by means of an oil expansion glas. The high-quality sealing on the agitator’s shaft with the SIC/SIC mechanical seal is also a feature of the BG500.

The standard piping for the PAULMICHL- agitator BG500 has an overall length of approx. 5.00 m. On request a shorter version can be supplied.

In addition, a very robust scraping knife for the propeller blades ensures long-term quietness during agitator operation.
