Aquascape 75003 Pond Air 2 Diaphragm Kit

Great replacement. Works great

Works perfectly

Why did you pick this product vs others?:The plastic for one of the pump arms broke after a few months of use, the original lasted 3 years. For the price you’re better off buying a new complete pump with new lines and diffusers.

Our couple air pump was only pushing air through one side. I contacted support and they said that the diagram needed to be replaced. Part was perfect. It was super easy to fix. Only three screws to take out and it is working great!!

My pond aerator stopped pushing air. The diaphrams were worn and torn so I went to the companys website to purchase this repair cartridge. $26 plus tax, plus a tariff surcharge, plus $15 shipping equaled $46. Nope!I bought this off Amazon for $20 plus tax and it fixed the issue. Its the exact part with the brand name on the package. Simple to install. 3 screws holding the pump together and 1 screw holding in the cartridge. Took me maybe 3 minutes.

This is my second one, The first lasted about 4 years. Beats buying a whole new unit.I run my aerator 24/7 almost year round

After four years of continuous use, one line from the Aquascape Pond Air 2 unit only produced a small stream of bubbles. Replacing the diaphragm took about five minutes, and it was not challenging. When reconnected to the tubing with the aeration stones, it was like having a new aeration system. The bubbling was prolific. I highly recommend.Autopsy of the retired diaphragmWhen I disassembled the retired diaphragm, I found cracks in both white plastic pieces radiating from the mounting hole the screw passes through. The silver horizontal screw secures the the white pieces to the blue divider between the two diaphragms units. My rubber diaphragms were not torn. The cracks in the plastic resulted in a loss of compression, which yielded fewer bubbles. While I had inspected the assembly for obvious failures before ordering the replacement, I did not lift off the diaphragm bellows which are simply held by tension. If I had pursued a deeper inspection, I may have attempted sealing the cracks as a way to revive the unit. I’d be interest to hear if anyone else found a similar failure point. At $25 dollars for the replacement, a repair really isn’t worth the time.

I noticed a decrease in bubble output. I thought my aeration stones were plugged...wrong. Turns out there were fractures in the pump diaphragm. I replaced in 5 minutes. Original lasted 2.5 years in Ohio.These pumps are simple and rugged.
