HEY GUYS JUST SWITCHED FROMPOWDER TO A MORE GENERIC LIQUID PRIMER AND OUR SMALL LINE OPERATOR IS HAVING SOME SERIOUS PROBLEMS PRIMEING DO YOU THINK ITS THE PRIMER OR MAYBE THE PUMP SOMEHOW.HE SAID IF HE PRIMES IN LINE ITS A LITTLE BETTER. WHEN I RAN THAT PUMP I ONLY PLUGED TWICE IN 9 MONTHS.

on my ball pump i had a 45 off the reducer with a 2x4 supporting it and my line had bentonite premixed or lime is better,i would put the hose 20 foot past the pump and roll a loop in it all the way out so it was all pre lubed even if i pluged when it got cleared and reconected the line had the rest lubed ready to go.

some guys literal put a little water in the pump and some in the line. then have the pump up to say 80 % speed and just hammer it down the line.

my problem with that is if you do not catch the plug promtly and i have 1100 lb of face pressure i plug hard and if i do not clear it in five minutes i will plug in the pump and have to open it up and make a mess.

i have not had much luck with slick pac and lime is an oviouse mess so the cheep way is to prime the pump into a five gallon bucket with a gallon of water and transfer it to another until it seperates then put it into the line, have the pump at half speed you can prime a long way.

         If the operator didnt have problems before, the easy solution is switch back.  Have him try puting the clean-out ball or something else in-front of slurry and push prime thru that way.
