Product Description

Hakko and Matala air pumps are the standard for most koi pond and water garden aeration needs. However, like any other machine with constantly moving parts there is a possibility for things to wear out over time. Much like a pond pump impeller, an occasional diaphragm replacement will increase the air pumps life expectancy and overall performance.

Tools needed:
- 1 small phillips screwdriver
- 1 medium phillips screwdriver
- 1 medium pair of pliers

Available Models:

HK-D25 - 25L Air Pump

HK-D40 - 40L Air Pump

Please Note:

If your air pump is suffering from frequent diaphragm blow outs you are most likely suffering from excess back pressure

Ensure air delivery tube is large enough enough in diameter and no kinking is occuring

Ensure air diffusers are not clogged. Cermaic stone style aeration diffusers require a muriatic acid cleaning every 3 months

Check that the size and number of air diffusers is sufficient to handle Hakko / Matala air output. Not having enough outlets or diffusers

  1. Easy to install 4 Star Review

    Posted by on Jan 31st 2018

    Product works as advertised. Pumps lots of air. Unfortunately it has to be replaced about every 1 1/2 seasons. So it is kind of spendy. In the end the health of the pond benefits greatly from being aerated. If it lasted longer I would give it 4 or 5 stars
