I got this pump years ago when it was virtually new and had been used to pump some aqueous oil/flux but wasn't the right one for the job so it was shelved after only a few hours of use.  It was given to me about a year later and I ran some water through it and it ended up on a shelf in my basement when I couldn't find a good use for it.
Before listing it, I retested it with some water and adjusted the controls and it reacted appropriately as far as I can tell, I didn't measure measure the volume of the pulses but it definetly changed frequency and stroke based on the sound and volume of water it ejected out of the top left port as seen from the front (currently has a plug w/ teflon tape on it in it).  The top right plug houses what appears to be a one-way valve with a diaphram, spring, cup etc. I did not get any water to come out of the top port but I cut the end of a Q-tip off and gently ran the stick into the top port which is not blocked and probably requires a change in the one-way valve or other plumbing to use.  I don't have the manual so I am not sure how to set it up to make the top port operate but I really didn't try very hard as I was just making sure that it still worked properly.  In my opinion this pump is 100% functional.  I believe that it is a diaphram type pump.
I have the original Instructions and will include them.
I ship Monday-Friday and typically ship 24 hours after the sale but on occasion, 48 hours after the sale is complete.
