Guys,

Need some input. I am getting a line pump for my concrete business. I have been using a pumper long story short with the size of my company i need my own pump.

The operator i have has trained with an experence line pumper for about 25 jobs and is good at it but here it gets cold and we add calcium to the mud and other stuff to make it faster.

Question 1: I have instructed my opertaor to not be afraid to turn down trucks that is not pumpable
(Hot loads) what is the general range for a bpa 500 to be able to pump slump?

Questions 2: If by some reason he pumps a hot load it flashes is there ways to save the hoses?

Thanks
Danny

Dont know much about that model pump but i can tell you that when pumping concrete be ready for anythin. From my experience i pumped some hot loads that pumped better then fresh loads and pumped regular mixes that pumped better then pump mixes or a stiff mix that works better then a wet one im just saying what works sometimes dont always work and sometimes what dont always works, works sorry i cant give you more info to what your asking all i know if you aint sure about what you gonna pump make sure you have a solid plan for cleaning your pump and lines cause its a lot easier then letting it get hard and having to hammer it all out.

Makes sence! Thanks

A few years ago we thought we lost some system,we were on a remote location and received a hot load. My operator was unable to crean out 100 ft of 3" hose. When he got back to the shop 3 hours later we used a sledge hammer and a power washer with a extendable wand. It was a lot of work but it worked.

Run over the individual hoses lengthwise from the middle each way with a heavy machine - like a squeeze pump to try to force the green mud out, or at least create some voids in it to have less hardened mud to clean out.  If it gets hard, then a sledge hammer to crush it somewhat, and/or a high preesure washer to clean it after the fact.

common pratcice, at least for me, when possible, is to pump water through system. should count strokes when primeing to get idea how much water youll need.(one hopper 2hoppers etc.) you will end up with a little sand inside on bottom of hose but when practical its a life saver.  "when in doubt water wash it baby!!"

When I get a clog in a hose, I replace the hose and have one of my guys take that hose and put it up on a forkift, and shake the hell out of it with both ends hanging down.  That gets most of it, and beating it with a 3 pound hammer gets the rest.  Then run water though it a few times.  If your not positive its clean, push a ball through it.  

I had a job go bad last spring,lthat's a storyin it's self..anyway.  I worked until 1am trying water washer with pressure washer etc and a got a couple cleaned. Started fresh the next morning using pump jocky's way first to break the old up by drving my hard tire fork lift over the hose. Then hung them up on the forks beat the crap out of the hoses let chunks fall. Them I made up a 20' pc of gavanized pipe with caps on it. Used a mall to beat it all the way though. Once I new they were clear I hooked them back up the the pump and water washed a pig though them. All 3" system. The 10'' pipes were easy,5' lenghts of hose were a pain in the azzz. I have since made a cap with a pressure washer fitting up but have not used it.Has anyone ever used the pressure washer idea? Terry
