Description
Eheim Vibration Arm with Diaphragm for Air Pump 100 / 200 / 400 – 3701 / 3702 / 3704 (7619780)
The Eheim Vibration Arm with Diaphragm (7619780) is a genuine OEM replacement set for the Eheim Air pumps 100, 200, and 400 (models 3701, 3702, and 3704). The vibration arm and diaphragm are the core mechanical components of the air pump — the vibrating arm drives the diaphragm back and forth to generate the air flow. When these components wear out, the pump loses output, becomes noisy, or stops producing air altogether.
The spare part set comes complete with instruction and Eheim special lubricant — everything needed for a complete, professional restoration of the pump's air-generating mechanism.
