Ideal for use in small fountains up to 1 meter (3 feet) in height, this smartpond® ETL listed pump never runs dry thanks to its patented low water auto shut-off feature. The pump's superior automatic shut-off technology is designed to prevent overheating by using a sensor that can detect when the water level is low. The pump automatically shuts off until it senses the presence of water and automatically turns itself back on. This oil free pump with magnetic drive is encapsulated with epoxy, allowing for full submersion and maximum durability with no harmful effects to the pump, fountain, or water. The pump features suction cups for mounting, a whisper quiet operation, and effortless maintenance. Submersion is required for operation. This product is backed by a 3-year limited warranty (2 years + 1 year for online registration).
