Advantages of ExtremeDuty™ Sludge Mixer

Warranty: Unmatched five-year comprehensive warranty covering parts, labor, and removal if specified.
Ragless Reversible Impeller: Features a dynamically balanced three-blade cast iron impeller that is self-cleaning and capable of forward and reverse pumping to manage foam and settled solids.
Bearings and Seals: Equipped with double-thrust and spherical roller bearings to prevent wear, and mechanical and double-lip seals for enhanced protection and abrasion resistance.
Grease Lubrication System: Utilizes less than 20 L/year of grease, with a low-pressure system that protects seals. The spent grease return system provides real-time information on seal and bearing conditions.
Mixer Housing: Rigid design eliminates the need for stabilizers or centering devices.
Impeller Shaft: Designed to avoid natural frequencies that cause vibration, ensuring a quiet and smooth operation.
Seal Tube: Allows for mixer removal without releasing pressure or draining the digester.
Design Flexibility: Can be mounted internally on the digester cover or externally with ground supports.

Drive Configurations

Standard Belt Drive Configuration: Includes an explosion-proof reversible motor, gear reducer, and flexible coupling.
Optional Direct Drive Configuration: Available for specific operational needs.

Draft Tube Heat Exchangers

Efficient heating and mixing with simple operation and maintenance.
Cost-effective solution that requires no sludge pumping.
Heat exchanger is wrapped around the draft tube and can be used with internal or external mixers.
