The 1/20 HP motor produces up to 15 PSI pressure and 0.7 CFM airflow. It draws only 1 amp, which means that you won’t have to worry about the costs! The manufacturer offers a one year warranty.
This is my second pump as the first one lasted about three years. The motor seized up when a Bearing froze up. Tried to replace just the motor but couldn’t find one. Great pumps for pond aeration
