HP-60/80 Air Pump Rebuild Complete Kit for Hiblow HP 80, HP 60, HP-80-0110 Aerators, Included Diaphram, Filter and Screws - Air Pump Diaphragm Rebuild Kit

Rebuilt pump 2 months ago. Checked pump today and pump not pumping. Diaphragm cups are warped and causing unit not to pump. Major defect in plastic. Past the return window

I’ve had to rebuild my pump and found this kit to be straight forward and easy to replace.

Ordered these replacement kits twice. I should have learned the first time. My Hiblo pump was 5 years old when we bought this house. The Previous owner said he had rebuilt the pump once. So I bought this rebuild kit to have on hand just in case. When the Diaphragms failed , i used this kit to replace them. i think maybe a week later , the diaphragms failed again , causing me to think the pump was defective. So I bought a new pump. Fast forward two and a half years, the diaphragms just failed, so I used these replacement parts to rebuild the new pump. Within 3 hours, the small plastic switch shear pin that came with these kits, had failed and the pump was off again. I replaced the shear pin with an old plastic shear screw I had, the pump worked for 4 hours then the warning light was on again. This time the diaphragms were fine, and the shear pin was fine , So I took the diaphragms apart again looking at what might be wrong this time. Turned out the Valve caps on the diaphragms were just horribly built. The caps should let air pass out of the pump, but not let air back into the diaphragm area. Both that were in this set allowed air to pass easily in both directions . I got the manufactures valve caps, and put them on , and the system is now operating for two days alright.. BUT , I have ordered a new replacement rebuild kit from the manufacturer, yes It's more expensive, but I know these parts are cheap now, and probably won't last long. I probably didn't need to buy the whole new pump the last time. It was probably just these parts prematurely failing then too. Lesson Learned. I won't be buying these replacement kits from Amazon or any other third party seller in the future.

I recommend buying the safety pin directly from the manufacturer of the pump. But the other parts are great and fixed my unit. Easy to install just look up a YouTube video.

Fast delivery, and it fit perfectly. Fixed my problem.

I read a lot of reviews before buying this product. I saw a lot of bad reviews, so I just decided to give it a try. When it came in, it was just the same as the old one. I don’t understand why a lot people wrote bad reviews. It work perfectly find. I had no issues to install it. It fit perfectly. I did not have to drill hole or make modifications. I did not use power tools, all was done by hand tools. It is a very great product for a great price. I look on eBay but it was more expensive.

Quick replacement and when diaphragms are snug works quietly

Did not hold up. Only worked for about 2 months.

Item fits well all works as it should.

Good product Price 🥲

My HiBlow 60 is used as part of our Bio Tec domestic waste water treatment system. I noticed the pump had stopped and found the diaphragms had failed after 7 years. The replacement parts kit came very quickly. Fitting the new diaphragms and plates was straightforward and quickly done. All working well now.

Emballage primaire mais arrivé sans casse, mais la commande n'est pas conforme car il manque les deux filtres du kit COMPLET. Je garde la commande comme cela, j'ai besoin de changer les membranes et comme il a fallu un mois pour recevoir ma commande je ne vais réattendre un mois de plus pour ne pas être sûre de recevoir une commande complète.

très bon, ça m'a éviter d'appeler bionest et probablement beaucoup moins cher, très simple à changer mais un peu plus bruyant qu'avant
