Maischebull-Hydrobull - Vertical Agitators- Mixing Systems
The powerful, large propeller agitators of the Maischebull® /Hydrobull® type make it possible to mix or stir in large quantities of solids in pre-pits, mashing pits and hydrolysis tanks. Especially with difficult substrates containing fibrous components such as solid manure or grass, this reliable and low-wear agitating system has proven itself effective many times over in combination with direct filling from wheeled loader buckets through a loading chute.
- Propeller diameter 1500 mm to 2650 mm (also with different profiles depending on the task)
- Erforderliche Deckenöffnung

- Gas-flushed parts in the tankStainless steel 1.4571 (V4A)
- Parts outside the tankGalvanised or painted/coated
- Base bearingSilicon carbide mechanical seal
- Propeller (Ø 2300 – 2650 mm)High-strength, wear-free polymer with steel core
- Propeller (Ø 1500 – 1900 mm)Stainless steel 1.4301 (V2A)
- ATEX-certified version for use in explosion protection zones 1 and 2
- Frequency inverter with parameterised safety software (torque limiting, coupling break detection, etc.)
- streisal "SafeGuard" (optional): automatic torque monitoring and control system with varying fill levels
- Shear-pin coupling as the final predetermined breaking point
The agitators are available in various ignition protection types according to ATEX for use in explosion protection zones 1 or 2.
With our extensive range of different impellers, drive powers and installation options, we can supply customised solutions to meet your particular agitation needs. One or more agitators are used depending on the tank shape, substrate properties and method of filling. References are available for agitation rates of up to 40 tonnes silage and solid manure per hour
The efficiency of our agitators is maximized by the large propeller and low frequency-controlled speeds. This is the only way to minimize the energy needed to convert electrical energy into agitation or circulation power.
Important wearing parts are mounted externally and are easy to access. It is therefore not necessary to remove the agitators or to climb inside the tank for maintenance and service work.
streisal Maischebull® /Hydrobull® agitating systems are characterised by great robustness and long service lives. Many of the components used have proved reliable in practical application for more than 15 years. With wheel loaders, wear-prone solids metering units are also not necessary during filling.
