Yong Heng water pump

[squirrel_hunter]

 the small pump supplied with the yong heng does a great job of keeping unit cool.filling rifles only takes under 40 seconds most times and temps rarely get above 41c....if your unit does not say yong heng on it its a clone...

Basically just rebranded..... generic. Like store brand goods.. only the label changes. We have a peanut butter factory here. They label the same peanut butter with whoever's brand places a large enough order.

I'm sure this has been asked elsewhere but while this thread is fresh, thought I'd bring it up.
Which nipple, top or bottom do you have the pump connected to?  I had mine supplying water to the top of the head, but recently swapped to the bottom thinking that there is probably air locked in the system with the top feed.
Temps seem to hold more steady not but then the temp sensor is at the bottom.  Maybe I'll clamp a sensor to the top of the head and get some more data.

     I finally fired mine up today. filled my disco in less than a minute, did that repeatedly. I'm happy. Soooo much nicer now not having to worry about having vascular problems while pumping. AND if any thing goes wrong I still have my hand pump to use. but so far I'm happy with mine. Now I can shoot my PCPs more, even though I still like my accurate cheap spring/gas guns too.

Yeah...600 GPH...but what would be wrong with 600 GPM...DEFINITELY lots of flow.

Just key in 6000 psi and 220 V...LOTTSA pic's...slightly larger, round head, different water in/out and other piping...works great so far...filled my 6.8 tank over two days...kept the temp to 60° C max...couple hours cool down to 3000 psi then overnight cool down, swapped in frozen 2 liter pop pop bottles, ≈50 Mpa at a time/20 min until EVERYTHING including me was too hot...it DOES GET HOT and pumps the room FULL of hot air...NOT GOOD ON A 90° DAY.

ANYONE KNOW HOW to remove the valve handle that has the pressure gauge in the  middle of the handle...https://www.ebay.com/itm/4500psi-PCP-Fill-Station-Valve-With-Hose-Thread-M18-1-5-For-Air-Tank-Paintball...I have air leaking out of the Foster male Fill Valve...can't seem to find any "remove Handle/repair kit/etc" for that valve.

Hope this one lasts a while...the two cylinder units will need to live in my garage.

Good Shooting

Thanks

If the foster male is leaking it's probably a bad o-ring in the base where it checks, take out fitting, unscrew at base and replace o-ring or replace with new foster male check valve, about $10 on Amazon. You'll need to know if threads are NPT or MM. Just a side note, the link above doesn't work.

Roger, roger..that's the one.   

Seems to have two opposite holes in the knob that correspond to something that looks like a pin or very small hex head behind them on the valve itself.  Haven't really messed with it as the tank is fill of air while I'm messing with the new compressor.

Looks like maybe a through pin that needs to be punched out to get the knob off...OR...  Didn't try to unscrew the handle to see if it came off that way...

Made up a FM foster with a  plug...it holds the air in and leaving on the fill hose does the same...just have to remember to dump the air before trying to hook up...pressurized foster valves don't like to be messed with.

Thanks for any help.

Good Shooting.
