Custom Pro Replacement Diaphgragm for Matala HK series D 60 or 80

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. Tools needed: - 1 small Phillips screwdriver - 1 medium Phillips screwdriver - 1 medium pair of pliers 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.
