Hand Pump for Chemicals?

SpeyFitter

Call me oldfashioned, but I don't get excited about having to set up a flush cart or another electrical pump just to pump a small amount of chemicals into a system. I'm curious what you guys use in the way of Hand Pumps that are reasonably effective and reliable - Mark you mentioned a Silver King Pump earlier. How does that work for you (I found their website).



Thanks,

Fantastic....

I modified mine quite a bit. I have a drain cock on the top so I can set it in the bucket, with a short piece of hose on it, release fluid into the bucket through the DC, close the DC and pump the fluid back into the system.



The only caution I would give is to make darned sure the body of the pump is completely drained before storing in vehicle during cold weather, or you will be buying another one... Don't ask me how I know that :-)





I used mine once to generate hundreds of PSI in an effort to dislodge "something" in a heating system. I am sure when I hit the handle with a hammer is was generating over 1,000 PSI if only for an instant. The "something" ended up being a red mechanics rag. Had to cut into a wall to get it out...

We always used these. They were cheap and lasted for a few acid washes if we flushed them out.

I agree with the previous posts. Keep it clean and don't abuse it. They pump on both the push and pull strokes. I had a system that was plugged with iron oxide, an 11/2" copper line in concrete. I hooked up the trusty Silver King and a 500 lb. gage and told my boss, you watch the gage while I give it what for. Well it happened to be on the pull stroke. I pulled with all my might and , the wind blew the **** flew and you couldn't see for a minute or two. The boss said that just before I ripped the guts out of the pump the 500 lb. gage was pegged. It did dislodge the plug and we were able to flush it out. bob

Remember the old

fluid hand pumps(maybe what bob means),,, looked-like a tire-pump on steroids,,, push-pull delivery ,but ours had no gauge,, wooden handle and a stirrup to put your foot-in,,,, I think it was red in color LOL .
