Covered by a one year warranty, these durable pond air pumps are the ideal choice for deeper ponds.

When you compare the total price of ownership of Medo Aerator Pumps, you willl realize these units are truly in a class by themselves.

Medo Air Pumps are the ideal choice for deeper ponds and have earned a reputation for offering superior performance and reliability over diaphragm driven air pumps. Compact, quiet, and functionally vibration free, the highly reliable Linear-Piston Pump will enhance your system's performance and extend its operating life. Medo aerators have about as much ambient noise as a light ballast, and consume very little energy. In an era where energy costs continue to rise dramatically, Medo air pumps have helped to drive down total costs of system ownership. Medo air pumps last longer, especially in hot, humid climates. Medo's unique linear free piston design has one moving part per piston - one. In properly installed and maintained wastewater systems, Medo piston aerators have an expected service life of 6+ years. A closer look within the Medo die cast aluminum housing reveals a pair of specially Teflon® treated pistons with extruded, hardened, and honed cylinders driven by highly efficient coils. The Medo, unified, heat sinking aluminum construction enables a greater, quieter operating aerator life, year after year after year.
Medo Air Pump's linear-motor-driven free piston system has an internal piston inside the cylinder which is driven by an electro-magnet and spring system controlled by the alternating input current cycle. The piston thus forms a single combined structure of two usually different devices; motor and pump. The system is quiet and vibration free, and offers the advantages of easy maintenance and a long operating life.
