Bonjour SVP pour les pompes booster de 50 à 600 GPD est ce que les têtes de pompes (diaphragme)sont les mêmes cad interchangeables et merci Hello please for booster pumps from 50 to 600 GPD are the pump heads (diaphragm) the same interchangeable cad and thank you

[@nutsathewheel]

Thanks for your video showing the pump dismantling and explanation of how everything works. I was able to get my pump working again after watching your video and learning about the operating principle. Keep up the good work!

[@tsbrownie]

Thank you.

[@jaypruiett2026]

Thanks much for this. I was trying to figure out if the rotating plate on the back was supposed to be centered. You clarified that it is not supposed to rotate centered. My SEAFLO 33 series pump (8A) is causing my boat battery voltage to drop from 12.6v to 10v when engine not running. I'm guessing I need to check the ground wire.

[@tsbrownie]

There are several things that could cause that. The motor could be going bad and is shorted. The wiring could be shorted. The battery could be too small for the job. The battery could be going bad. Etc.

[@theengineer70]

my 2006 8009 has some slight suction on start-up, which quickly dissipates (i.e. no more suction) at the intake (no hose). if i manually feed water into the pump, the pump does create pressure, eventually maxing out and turning the pump off. so the switch is working and the pump makes pressure provided i feed the pump manually. does this mean the rubber valves on the suction side are worn out? i've taken it apart and cleaned it several times, so i'm certain its not debris in the pump. the unit is on a pressure weed sprayer. hate replacing it, we've been through a lot together, but i'm not sure its economical to rebuild. excellent video, btw, exactly what i was looking for to understand how this thing worked.

[@tsbrownie]

When mine fail, it's always the valves that break down.

[@theengineer70]

@@tsbrownie $40 for the valves, i think i can work with that. replacing more than that starts creeping into replacement cost territory. thanks.

Awww man awesome video, it help me a lot and now i understand how that pump works. It's very nice that you showed how the pump works dismantled into parts, thanks to which you can see what effect is created inside.

[@juppster5694]

Thank you, that was a great explanation! Pump in my undersink RO has just failed (leaking) and at least now I can see how it was *supposed* to work. I think diaphragm must have split :-( As you say, the motors are quite handy without the pump head, so I think I'll just replace it and score a useful DC motor. You never know when it might come in handy!

[@henningandrefinstad1805]

Great video. I have this kind of pump in my motorhome and want to prepare my motorhome for the winter. How can I empty the pump for water so it will not freeze during the cold winter in Norway ? Is it possible to use a vacuum cleaner to suck or blow (for example from the bathroom). Will this completely emptying the pump ? Or is the best way to run the pump for a little time with no water in the system ? It is the pump that is the issue here, not the plumbing system.

[@tsbrownie]

In theory you could run it with an open input line for a while. Or blow air in the input while running it. It's probably safest to loosen the screws and open the chamber a crack. The orientation can make a difference how much water is left inside. Or you could clear it by running alcohol through it! 😉

[@sridharanp]

[@tranducdu3596]

Great share, thanks

[@bibhasjana6040]

explained beautifully, thank you.

[@bestillandknow3939]

Was hoping for some troubleshooting tips. Specifically, what should be the intake pressure? You said output should be 30 -40 lbs. However, to test in field means to flood the host structure (in my case a camper) with water. There is a -t-junction on the input side with siphon hose (for winterizing -one side of the T is to the fresh water, the other the siphon hose. If I test the suction pressure there, what should it be?

[@tsbrownie]

This is a high pressure pump from an RO water filter. I have no specs for camper use. Output max is around 80 psi and varies with manufacturer.

[@joesapp4908]

Many thanks - Helped me troubleshooting mine which stopped working after very little use (filtering distillates) and I feared the rubber had perished, but it seems I gunked the valves! All working now, thanks!

You're welcome. I'm not sure if they can. That's up to the manufacturer.

[@triplediff]

Cool video! I had a summer job assembling diaphragm pumps, and although the concept is exactly the same (piston opening and closing a chamber with 2 valves) the manufacturing process was much different. We also made pumps with 5 chambers "taking turns" which further stabilizes the flow.

[@tsbrownie]

That's interesting. What were they used for?

[@triplediff]

@@tsbrownie mostly inkjet printers, but also for biochem labs and in coffee machines. Seeing the manufacturing process behind the things we use in daily life is really fascinating! I appreciate the video 👍

[@jacobrothschild42936]

My freshwater pump has been cycling every few seconds, but I had no leaks anywhere. So I opened up my pump to clean out the trapped debris (fixed the cycling issue) and was amazed at the internal mechanics. I thought they were just one plunger with a check valve on each side. What cool engineering! Thanks for this video!

[@tsbrownie]

You're welcome.

[@rorschach2857]

I have the exact same issue! But I've opened it up and can't see any obvious debris, there's some scum that I've cleaned but it's still turning on every 10 seconds or so... I ran a continuity test in the pressure button and it seems to be functioning well. Any other ideas?

[@tsbrownie]

@rorschach2857 There's a one way valve. If it's leaking that might be it.

Do these pumps create enough pressure that i can use them as a compressor for a project?

[@tsbrownie]

They are water pumps and the ones I have produce about 80 psi max. They are from RO water filters.

[@jawaharlalsah1254]

Excellent demo, great

[@VanwithTim]

I hear about the diaphragm pumps dying in RV applications over the years... Wonder what piece fails? Seems the design is relatively bulletproof.

[@tsbrownie]

That's a good question. I've had 4 pumps now, and in every case it's the rubber valves that rot first, followed by the "pistons." If the rubber parts were of silicone rubber, I'd guess the things would last 10x longer. I've tried to find replacement parts, but of course they have no financial incentive to sell those. Plus none of the pump brands I've seen have interchangeable pump parts, although the motors seem to be more standardized (but I've never seen a motor fail first).

[@VanwithTim]

@@tsbrownie That's unfortunate about the rubber deterioration but makes sense. A "service kit" of new rubber valves could be sold for $5 while still making a huge profit, but I'm sure the manufacturers make bigger $$$ by selling whole units. Sad state of our throw-away society I suppose. Appreciate the input, and thanks for the video!

[@tsbrownie]

@@VanwithTim In Europe there is a big "right to repair" movement going on. We need that also. BTW I have seen a couple of your vids, about an AC and solar for your van.

[@triplediff]

@@VanwithTim I actually worked for a company that would in fact sell existing customers replacement part kits that mostly included the rubber bits that fail first. I put together over 1000 of them.

[@magnagei]

Very clear explanation

[@anilshahi1990]

Can I replaced the head with other pump head.

[@tsbrownie]

I have looked at that, and the other brands have small differences that keep the heads from being interchangeable.

Great design!

[@adeyemibabatunde1814]

@tsbrownie Excellent video, Can the pump be used to pump air or create vacuum? What is the wattage of the pump?

[@tsbrownie]

No, they are not good air pumps. Wattage depends on the model. Some are 12 volt, others 24. Some are 1 amp, 2 amp, 2.5 amp .... just multiply the volts times the amps of the model you are interested in.

[@sacdesaram]

@@tsbrownie Thank you for your reply. Does the air pump have no diaphragm?

[@tsbrownie]

@@sacdesaram There are many types. Small ones use bellows. Mid-size are often piston type like car-tire pumps that will run long term (car tire pumps won't). Big air pumps are like turbines. There are more types and you can search on google "different types of air pumps" and see most.
