Hello,

i'm looking for advice for cheap and decent desoldering pump. currently looking at S993 and proskit SS-331H.
they are about the same price, proskit have dedicated station which should be easier to repair.




anyone have any experience with this ?

thank you

The first one looks like a re-hashed ZD985 and some say the other one sucks...  :-DD

It's about a 50/50 mix of real world experience and google/crowdsourced speculation/ponitification/pulling it out of someones arse.

That's a higher proportion of real world experience than is generally found on a forum, so I think we're ahead.

I have built a couple... DIY... I made it rather fancy, for less than $50, as I recall. I used nebulizer pumps, from the thrift store. Open it up and change the output hose, to be the input hose. Change the hose to automotive silicone, so it won't melt. Second critical part is the soldering iron. This type... https://www.amazon.com/ECG-J-045-DS-Electric-Soldering-Temperature/dp/B00068IJSG/ref=sr_1_fkmr0_3?ie=UTF8&qid=1535705683&sr=8-3-fkmr0&keywords=desoldering+iron+bulb It has a changeable tip and a suction bulb. Cut the suction bulb pipe, about 1", from the head. You need it to be short, so the solder doesn't cool in the tube. Add a small aluminum fuel filter, at the head, with a short piece of tube. Stick the soldering iron tube, onto the suction hose. I added a footswitch, power supply and solid state relay, to drive the pump. Works well. And, you can save up for a Hakko... But, I like mine well enough, as is. YouTube has examples. Also, watch videos, there, on how to use a desoldering pump... There are a few tricks...
