Secoh SLL Air Pumps

Secoh Air pumps have a well-deserved reputation as top quality pond air pumps. They have established themselves as the number one choice with many experienced keepers of Koi.

Secoh Air pumps are made in Japan and are of excellent quality, represent real value for money and will give years of trouble free service. Waterproof and very quiet and proven to be the most powerful air pumps available today. For example the Secoh 100 actually produces 145 lpm of air, and the 40 produces 60 lpm. Secoh Air pumps have won 'best pump' in just about every independent review of air pumps to date!

Not only are the Secoh air pumps extremely powerful and reliable they have the big advantage of having a rainproof cover that makes them easier to install than many other Pond air pumps.

Specifically designed for use with larger Koi ponds, where the ability to pump to a good depth, with several air stones or Aerated Bottom Drain is important, they are well made and good value for money.
