Anti-clogging design
By employing a solid-liquid separator or a cyclone cutting system, contaminants (such as fibers and solid particles) are isolated or comminuted prior to discharge. This prevents contact between the pump impeller and foreign objects, effectively addressing the issue of frequent blockages common in traditional collection wells.
Certain premium models (e.g., German brands Herbor and Denor) incorporate selective cutting blades that process only essential debris, reducing energy consumption by up to 68%.

Sealed and odor-proof construction
The integrated sealed tank (constructed from 304 stainless steel or HDPE) is equipped with dedicated vent pipes to prevent the volatilization of sewage odors, thereby ensuring basement air quality.

Intelligent control and low maintenance
The system supports fully automatic operation: pump activation and deactivation are governed by liquid level sensors (low/high/ultra-high), featuring multiple protective functions including dual-pump alternating duty, fault crossover, and forced drainage modes.
Backwash technology utilizes the pump's discharge pressure to reverse-flush debris temporarily retained in the separator, providing a self-cleaning functionality that significantly reduces maintenance requirements.

Compact and flexible installation
The unit features a small footprint (e.g., residential models with capacities as low as 20 liters), pre-configured multi-directional inlets (DN50-DN150), and is compatible with clamp or flange quick-connect fittings, making it suitable for confined spaces.
