The RA mixer was designed for mixing and stirring liquids in containers in the food sector.
The mixer is put into operation using a start switch fitted on the side of the motor that has an under-
voltage release.
All metal components that come into contact with the product were made from stainless steel.
The mixer is connected to the filled container
- by the corresponding container fitting
- angle seat valve
- straight-through valve
- sluice gate
and the flap gate.
The retractable agitator shaft can be attached to the front of the container and the propeller can be
inserted into the medium without causing a loss of liquid or pressure. The special bearing of the
agitator shaft in the hollow shaft of the electric motor ensures that the mixer operates quietly and
without vibrating. The mechanical seal will operate without malfunctioning if subjected to a load of
up to 10 bar over the long-term.
CAUTION
When switching on or switching off the device, a minimum quantity of the fluid product will
escape. It is important to ensure that the fluid product is fed away securely!
NOTICE
• The under-voltage release prevents the risk caused by a sudden start-up in the event of an
unintended power connection. This is achieved by the machine becoming fully-functional
again after the triggered switch is actuated.
CAUTION
Risk of injury or damage to the agitator vane, etc. !
• It is not permitted to switch on the device without attaching it to the container and snapping in
the agitator shaft coupling!
CAUTION
• Pressure may only be applied with a specific agitator shaft and flange housing fastener.
• Please note that a special mechanical seal is required when the mixture is stirred aggressively.
