Medo LA-45B Air Pump LA-45B

  • Life expectancy of 6 years can be seen with proper installation and maintenance of the pump
  • Quiet operation allows the pump to run without disturbing anyone while you relax pond side
  • Designed to self-adjust should the pressure exceed the rated value of the pump, the piston stroke will automatically shorten to reduce the strain on the pump
  • Environmentally conscious design allows the pump to operate with lower energy consumption as it requires only 50-60% of the line current typically used by diaphragm pumps
  • UL-listed for outdoor use

Medo Air Pump's linear-motor-driven free piston system (Pat.) 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.
