Inclusive Scope of Supply:
1. High-quality submersible reflux pump;
2. Robust installation system;
3. Advanced electric control unit;
4. Essential connection attachments.

Important Notes: While the wall-threading pipe requires pre-embedding, both the guide rod and lifting rod can be securely attached to the pond wall using expansion bolts, eliminating the need for additional pre-embedded components. Pre-embedded parts and flap valves are to be acquired and installed independently by users. Users can choose between horizontal or vertical installation of the reflux pump to suit their specific needs.
