Submersible cutting pump
The all-purpose machine for stirring slurry, pumping, flushing sewers, and filling barrels.
The entire machine is hot-dip galvanized and, depending on requirements, is driven by a
15 hp – 25 hp electric motor.
Data:
- Entire machine hot-dip galvanized
- Drive power 15 hp – 25 hp
- Mobile or stationary
- Also suitable for greater depths
- Various applications

Submersible slurry pump with cutting mechanism
The ideal submersible pump for slurry applications. The special cutting mechanism easily shreds even slurry with an extremely high straw content. The pump is used for flushing sewers, transferring liquids, filling barrels, and stirring.
Data:
- Special cutting mechanism
- 13 hp – 25 hp drive power
- Maximum delivery rate

Hose reel
Compact hose reel for 400 m or 800 m hose.
Hydraulic drive with safety bar and speed control valve. The reels can be equipped as single or combination units with distributors.
Data:
- For 400 m or 800 m
- Capacity
- Safety bar with
- Speed control valve

Slurry hose
Special high-pressure hose for slurry transport, designed to meet the highest demands (2-year warranty). High tensile strength thanks to high-quality polyester fabric reinforcement. Abrasion-resistant thanks to special rubber coating. Various sizes available.
Data:
- Hose diameter 65, 75, 90, 100
- Operating pressure 20 bar
- Burst pressure 50 bar
- Tensile strength up to 11000 kg

Slurry spreaders
Electric slurry spreaders in various versions, from simple manual operation to fully automatic operation from the vehicle.
With 3-point suspension or in combination with a hose reel.
Data:
- Various models
- 3-point hitch or
- combination with hose reel

Trailed hose distributor
The drag hose distributor ensures slurry spreading with minimal nitrogen loss and odor emissions. At its heart is the distribution head, which is made entirely of stainless steel. It is designed so that even slurry with a high straw content can be spread without any problems. The distribution hoses have a diameter of 50 mm. They are driven by a hydraulic motor, which requires only a small amount of power (approx. 30 bar). The clog-free, slope-compatible distributor ensures precise manure spreading. The chassis is completely hot-dip galvanized. The drag hose distributor is available in 4 sizes (5.1 m, 8.4 m, 12 m, and 15 m) and can be attached to the 3-point hitch or the pressure tank.

Data:

- Sizes 5.1 m, 8.4 m, 12 m, and 15 m
- Stainless steel spreader head
- Low power requirement of approx. 30 bar
- Distribution hoses ø 50 mm
