Air Products for Koi Ponds >> Secoh 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.

• Oil free
• Silent operation
• Robust design
• Low Maintenance - Just occasional filter change necessary
• Long life expectancy - Up to 35,000 hrs
• Rainproof enclosure - Conforms to UL1450
• 12 month warranty

One more thing we would recommend that a Pressure Relief Valve be used with these pumps to avoid over pressurisation and damaging your Air Pump.

These pumps run 24 hrs x 7 days a week, so that's 8,736 hours a year .. non-stop!. Your car gets more than just a filter clean annually and at most probably runs for only 400 - 500 hours a year, treat your pump like the machine it is and fully service it. If you look after it properly you will be helping to extend its life and give you trouble free delivery of air.
 
Kit contains all the parts required  to service the following SECOH pumps:

Single Air Pumps: SLL-40 and SLL-50

Kit contains : Magnet (without screws) to replace original in SLL pumps.

Due to the high strength of the magnets we STRONGLY recommend removal of watches to avoid damage to them (and keep them well clear of any magnetic data storage!). Also avoid the contact of the magnets with metallic components as the magnet may be stronger than you expect and may suddenly attach itself, pinching anything in its way!

We accept no liability for loss, injury or damage in fitting the magnets.

Sorry, this has to go via a courier service (apparently the Post Office don't appreciate their stuff being messed up by a stong magnet in a jiffy bag)

We now have something that you will all need and to save you blowing those diaphragm's, we can now supply a Secoh Air Pressure Relief Valve,  this fits between the Air Pump and the Manifold, no tools or skill needed. 

We highly recommend the Secoh Air Pressure Relief Valve, it fits all Air Pumps and operates automatically when too much pressure is detected. The Secoh Air Pressure Relief Valve is recommended for larger air pumps, where back pressure created by insufficient bore air piping or too few outlets being used can quickly damage the pump diaphragms.

This Secoh Air Pressure Relief Valve is a pump protection device against over pressurisation. The valve will safely vent off any pressure over 0.2 Bar. If your valve is opening you have a blockage!, check and replace the offending area, be it a kinked pipe or blocked airstone!. Without this valve you are relying on the BP1 gauge, if you have one, as a monitoring & protective measure on your system.

Secoh Air Pressure Relief Valve kit contains : valve, 2 x short ribbed connector pipes and 4 no clips.

The Secoh BP1 Pressure Gauge is a great tool which ensures that you are running the pump within its limits. Leave the gauge installed at the outlet of the pump.

One of the most common causes of pump failure is due to blocked diffusers, especially when used in aquaculture applications. When using old diffusers or diffuser 'air stones' ensure they are regularly cleaned and better still replaced annually.

The idea with the Secoh BP1 Pressure Gauge is to monitor the pressure that the system is running at, if the pressure in the system exceeds what the Air pumps are rated at then it will only be a matter of time before you will have a failed pump.

i.e. The Secoh SLL Air Pumps & the Secoh EL Air Pumps are rated to 0.2 Bar, the EL-Twin pumps are rated to 0.25 Bar. We strongly recommend you buy a Secoh BP1 Pressure Gauge and check it regularly to save the life of your Air Pumps.

0 - 1 bar gauge assembly, complete with 2 x 3/4" hose tail connectors.
