Seepex, a German pump manufacturery, has optimized the performance of its progressive cavity pumps by using razor-sharp macerators to reliably shred solids and fibrous materials into the smallest particles. This prevents pipeline blockages and ensures reliable protection of downstream system components.
Cotton swabs and wet wipes in wastewater, bones and fishbones as well as shells, pits, and fibers in food production – many industrial waste processes end in a liquid, pumpable suspension that still contains solids and disruptive materials. These can significantly impair subsequent processes. The Easy Maintenance Macerator homogenizes sludge through an efficient shredding process, ensuring smooth transport of the medium through the pump. This increases operational safety and minimizes the risk of disruptions throughout the entire plant process. Key technical highlights include:
- flow-optimized shear plate geometry,
- durable, replaceable knives made of highly wear-resistant tool steel, and
- a reversible shearplate.
The design allows easy and quick access to the cutting unit – both for maintenance and for removing foreign objects – without lifting equipment. The macerator achieves a throughput of up to 100 m³/h with motor ratings of 1.5 kW (standard), 2.2 kW and 3 kW.
Quick access and predictive maintenance
The foldable cutting unit allows convenient opening of the machine from above. The shearplate is easily accessible and quickly replaceable. Blades can also be mechanically adjusted from the outside. Cleaning and removal of foreign objects can be up to 80% faster. An optional reverse operation is available: the knife rotation direction can be changed during operation. Blockages can thus be cleared without opening the macerator.
Additional operational safety is provided by an integrated debris separator. A separate cleaning flap allows direct access to the housing, enabling quick and easy removal of disruptive solids. Main applications are in
- municipal and industrial wastewater treatment,
- agriculture (especially biogas production),
- the food and beverage industry,
- fish processing,
- paper and pulp production, and
- sugar refineries
– in short, wherever coarse and fibrous materials must be shredded before the pumping process.
