Blue Diamond Air Pumps Aeration Kits with Matala Air Diffusers

We designed these kits to team up the air pumps with compatible diffusers. Please note that kits may ship in multiple packages from multiple warehouses.   Also these kits are mostly designed for ornamental ponds with shorter tubing lengths.   Dana or Nate at 484-237-2080 will be happy to help you design an aeration system for your larger natural ponds and lakes.  

Note: The Blue Diamond ET series aerators are designed for relatively low pressure. Tubing should not exceed 130' and diffusers should only used in water up to 7' deep.

The Blue Diamond ET Series Air Pump Complete System Kits are set up for simple and quick installation. Each kit includes an air pump, along with the manifold (if required), weighted airline tubing and diffusers needed for pond aeration.

ET Series Air Pumps
Blue Diamond ET Series Air Pumps are versatile pumps that can be used in aquariums, ponds and certain septic applications. The weatherproof pump has a robust and compact construction, and the main body is constructed of cast aluminum alloy.

• Energy-efficient Green Drive technology means low power consumption
• Suitable for intermittent and continuous duty applications
• Replacing diaphragms makes it simple to return pump to full performance
• Specially formulated diaphragm material for extended life
• Made in China

Connections
Air outlet is threaded inside for use with included barb adapter, but we recommend instead using the provided rubber elbow when connecting 3/8" tubing. Larger tubing may be connected directly to the smooth outer surface of the air outlet. 14mm outlet can accommodate 1/2" tubing, while 18mm outlet can accommodate 5/8" or 3/4" tubing. To use 1/2" tubing with 18mm outlet, you will need additional adapters.

On all models where the brass is used to connect to a septic pump alarm, the brass is 4mm.  

2 Year Warranty
This warranty does not include the diaphragm kits, which are a replaceable, wearable part (typically replaced every 12-18 months). Warranties are at the discretion of the manufacturer as to whether the damage is due to misuse or to defect.

PGP Tip
The most common problem with this and other larger air pumps is premature diaphragm tearing due to excessive back pressure. People don't tend to understand how much air the large sized pumps produce. If an air pump is powering too small of a diffuser or too few outlets, excessive back-pressure can occur. The solution is to add a tee with a ball valve or other "bleeder valve" so that excessive air can be bled off into the atmosphere. Start with the valve completely open and slowly close it until you have the maximum output from your air diffusers without unnecessary back pressure.
