Matala / Hakko HK-D Replacement Diaphragm Kits | 4 Sizes
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 components 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.
For detailed instructions on how to replace the diaphragm, take a look at the instructions under the "downloads" tab.
Tools needed:
- 1 small Phillips screwdriver
- 1 medium Phillips screwdriver
- 1 medium pair of pliers
Available Models:
Rebuild Kit # HK-D25 for 25L Air Pump
Rebuild Kit # HK-D40 for 40L Air Pump
Rebuild Kit # HK-D60 / HK-D80 for 60L & 80L Air Pumps
Rebuild Kit # HK-D100 / HK-D120 for 100L & 120L Air Pumps.
Please Note:
If your air pump has frequent diaphragm blow-outs you most likely have excess back pressure resulting from an incorrect set-up.
Ensure air delivery tube is large enough in diameter and there is no kinking.
Ensure air diffusers are not clogged. Ceramic 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 will create excess back pressure.
