The Digester Cover Pump™ by AER-USA is a fully integrated, C1D1 explosion-proof pumping system designed specifically for the removal of rainwater from floating or membrane-covered anaerobic digesters. By preventing water accumulation, the system protects gas storage capacity, prevents structural strain, and helps maximize methane yield.

​

Engineered for durability and ease of use, this portable unit features a heavy-duty plastic pump housing, integrated float switch for automatic activation, and a certified C1D1 junction box for use in hazardous biogas environments. A custom-built handcart allows safe transport over HDPE or flexible digester covers without causing damage. With plug-and-play functionality, it installs in minutes and requires minimal operator intervention.

​

Key Benefits:

✔ Maximized Gas Production Efficiency: Eliminates rainwater weight that reduces cover volume and gas storage.

✔ Explosion-Proof Safety: C1D1-certified components ensure safe operation in methane-rich environments.

✔ Automated Operation: Float switch activates pump without manual input—ideal for unattended use.

✔ Cover-Safe Mobility: Wheeled cart is designed to prevent tearing or puncturing of membrane surfaces.

✔ Cost-Saving & Durable: Prevents structural damage and maintenance downtime caused by standing water.
