The V-belt not only offers maximum protection for the drive motor; it also protects against breakage of the drive shaft should the mixing propeller become obstructed by a foreign object. 6-pole motors with a speed of 1000 rpm and an output of 7.5–22.0 kW are used as the drive motor in this design. Depending on the size, the high-torque electric motors make it possible to reach mixing propeller speeds between 300 and 400 rpm. Thanks to the high torque, propeller diameters of 500-600 mm are possible. The efficiency is significantly greater than with the standard electric motor 1450 rpm. Supplied as standard with a pusher propeller without a switch or interval control. The mixer can be retrofitted with an angled drive making it suitable for virtually any application. The mixer is supplied as standard with a pusher propeller but excluding switch and interval timer control. The mixer can be retrofitted with an angled drive making it suitable for virtually any application. The three-part drive shaft is of a modular design. The upper and lower sections of the drive shaft are fitted with 2 taper roller bearings each, while the centre shaft section has a deep groove ball bearing. The maximum bearing spacing is 1500 mm. The mixer is oil filled is of a very low maintenance design and can be used for continuous operation, 24/7, up to 1000 rpm. The drive shaft is sealed by means of a SiC/SiC mechanical seal. The front drive shaft is sealed using a cartridge seal The special seal is moisture proof. Air humidity and rain ingress are therefore no longer an issue. The front drive shaft is equipped with a PTO spline in accordance with 1 3/8” Z6 DIN 9611 which enables combined electric/tractor drive operation. If a tractor is used, the V-belts must be removed. If the unit is installed at floor angle, an oil expansion tank must be installed and the oil refilled.
Application: Fermenter
- The mixer can also be installed and removed with a full tank
- The biogas digester can continue operating with no downtime
- The installation and removal of our mixing system can be completed from the outside without it, being necessary for a fitter to get inside the tank.
- The medium can be fed into the tank during mixing and is immediately and completely mixed through
- Trouble-free stirring and mixing is ensured because there is no installed equipment to interrupt the flow
- Can be used in all types of tank
- The mixer is not located in an explosion protection area
- Can also be retrofitted to all existing systems
Flexible and customised.
Various equipment variants, attachments and accessories are available for our agitators and systems.
