1. Introduction
The Jebao ECP-50M Smart Cross-Flow Pump Wave Maker is designed to create optimal water movement in aquariums. This pump utilizes SINE wave technology for quiet and stable performance, featuring a cross-wave single impeller structure to ensure efficient water flow without dead spots. It is suitable for both marine and fresh water environments as it contains no exposed copper elements. The ECP-50M can be operated via a manual controller with an LCD display or through Wi-Fi using the Jebao App on iOS and Android devices.
