This is a stupied question.But how do you prime with water? I would think it would seperate the concrete in the boom.I would be to worried about plugging. I run a little 28m putz.If some one can help it would make my boss happy.I use bentanite now

Thanks Scott

This is easy man. Put water half way up your cylinders. Put the mixer chute at the edge of your hopper. Start stroking wide open intruduce the concrete slowly at first so it pushes the water into the cylinders then have him pour it out fast and you will be primmed out my brother. I have water primmed my 60m this way many times without a prob.

not all pumps have a prime port, but if you do, you can have the driver fill the hopper first, than fill your prime port w water, install the cover than turn the pump on, have you ever been on a job, the driver starts to fill your hopper than along comes the inspector and says stop, meanwhile your thinking  i cant stop i have to start my pump and prime out before i plug, or you get half a hopper before the driver plugs the shute, and your thinking  come on i have to prime now......  if you have a prime port,  i can have the driver fill my hopper, than i can wait 1, 5, or 10 min before i do anything, (cause i have not put water into my prime port) im not under any pressure to hurry up and prime, 5 min later i can pour water into my prime port  ( and the water is still not touching the mud) wait 5 more min than turn the pump on, (untill you turn it on the water is still not touching the mud) or you can prime through the hopper like bri said, but as soon as the driver starts to discharge the mud you have to do something right then, iv done it both ways, you can cut a prime port into your reducer if you dont have one, the biggest pump iv owned is a 52 putz, i always used the prime port and only used water, i NEVER  had to remove pipe because i plugged on the prime, but like i always say you have to do whats comfortable to you, if you like to use a priming agent than by all means use it, the mud in your area may not be as good as the mud in my area, at the end of the day a pumper in colorado might go to the lake and the pumper in calif might go th the beach, in different areas different things apply

bri has the right idea dude ! fill hopper up to cylinders about 3 inches over bottom of cylinerds , stroke over maybe 6 times , put concrete in hopper , i go a little over half throttle , a let her rip , its easy once you do it you will do it every day

Other than forgetting your slick-pac or the driver filling the hopper before asked,why would you want to prime with water?And don't tell me to save money,that just don't fly.

I use water to prime the pipe ahead of the grout that is priming the pipe for concrete.

The only time I ever used water to prime the pump was on the old Schwing gate valves.

Those bigger pumps usually water wash, and have really clean pipes. Water priming is fine if your pipes are clean, or the second pump of the day. Some times on monday I use slick pack just for peace of mind. Last spring I primed with water, with bad footing mix concrete, and dirty pipes. It wouldn't pump, I had to dump the hopper and prime with mason cement,once the mud was moving it cleaned the pipe and pumped fine. Since then I've used slick on first primes. Prime ports are great, but I don't have one yet.

i use water, if im sucsessfull all the time why would i want to have to use an additive, some guys say its only $3 bucks, but why would i want to throw away any money, here is something for you guys to think about, you guys that use one bag of primer,  what if i said you should now use 2 bags instead of 1, you would say you only need 1 bag to prime with not 2 bags, well the same thing applys here why would i use 1 bag, if i can do it w only water, the other thing is, after reading b-alto s post i started thinking ( i know thats dangerous) let me ask this is it the same guys that suck a sponge that are priming w something and do the guys that water wash prime w water, i dont not use primer to save money, when i started pumping concrete, i was taught to prime with water ( that was a line pump in 1982) when i got my first boom, the guy i bought it from told me to prime with water, after he said that i never had a second thoght about it, im sure every area is different, mixes differ from area to area, even in my area we sometimes get mixes we dont like, and they pump like crap,  i didnt even use up all the sampels they sent me, i didnt like it, after a few times i didnt feel it was worth it when i had been doing it suscessfully for years with out it, im not here to tell any of you that you dont need primer,,,, but i will say, I dont need it,

so tell us your combination

do you 

water wash and  prime with water

water wash and use primer 

suck a sponge and prime with water

suck a sponge and use primer 

also tell us

what area your in

size pump you run

where you prime from (hopper or prime port)

are most of the mixes in your area what you would call good

you could even tell us rock, sand and cement  weights so we can compair how mixes are different around the country

Here is how i do it....


Well first off I water wash,That being said...

I run a 47 meter Schwing..NO PIRIME PORT

I fill my hopper with water about 3to5 (just a guess I stop when i feel thats enough)inches up the cylinder.

Then with my RPM's at around 1600 and at about 70% volume I make about 6 or 7 strokes in forward.. this gets the water into the Rock Valve

I stop the valve as soon as it shifts

Then i put the RM truck chute on the same side of the hopper as the valve

As soon as the contractor is happy with the slump of the mud I tell the driver "fill it up"

With the auger in forward i let the mud get up to about the auger and turn the pump on

with the chute dumping mud on the same side as the valve this forces the water in the bottom of the hopper up into the exposed cylinder I have never had a problem priming this way

I also prime with water unless i'm doing line jobs then i'll use a primer or if enough line i'll have the contractor order grout. But with my boom i just use water i don't water wash just put little water in hose and suck ball back pipes stay clean lol as long as you catch ball in reducer. I want to know how you clean dirty pipes out on one job? I've ran pumps with dirty pipes usually find the build up in reducer when it breaks loose.

when i started pumping in 1984, the contractor was required to supply grout to prime with,, when i went to work for a different pumping co, we would cary a 90lb bag of portland to prime with,, i got tired of breathing the cement dust,, one day a put water in the hopper, full throtle on a 1001 28 schwing gate and let it eat,,  only way to go!!!

I'm curious about how long the rams last in your pumps. With all of the dry cycling of your pump they can't last long. The company that I work for keeps track of how many yards you put through a set of rams. If you change them before you get a certain amount of yardage, they think the barrels are not aligned,or the pump is being dry cycled.

I prime the same way that WHO does, but I don't cycle the pump at all unless the barrels are lubricated.

i prime only with water 98% of the time. never have problems except with certain ready mix company who wants to save money adding less cement and adding more rocks then they suppose to. even the mixer drivers call the plant to say its a shit load and all they say is the mud is ok, the problem is the pump. they are such an a*^h_#s.

18: I can water wash,suck a sponge and do the Carolina mud puddle wash(also known as a bucket wash),and still I prime with water.I run a 47m schwing with 100,000 yards on the clock, second set of pipe,third set of mud pistons and the Original cutting ring.What you prime with really doesn't matter!

 On the average I use about 8 pacs a week,that cost us 24 dollars.I charge the customer 20 bucks, turns out to be 136.00 profit per week.5000.00 profit for a year.Multiply that by,say a dozen pumps,big chunk of money.Almost 700 % mark up.By the way if I use water,the customer will still get charged 20.00.

its funny different parts of the country do things a lil different, but we all try to get that extra $25 bucks out of every job (because it really can ad up to a lot) but we are all still devided by regon, each area is different, in your case ( and im sure other people do the same thing) its the prime out charge, here in so cal we dont really get a prime out charge, it just woulden fly around here because the contractors know that we have been priming out with  water for a long time, if any slimey stuff came out of your tip hose here, they would look at you  like you were from mars, but dont worry we have our own ways of getting that  $25 bucks, we cant charge them to prime so we get them with a wipe down fee, after our cleanout time we get a extra half hour to wipe our pumps down, i think every company here in so cal does it, we get them dirty on their jobs, and they got there clean,  and so now we make them pay,   good thing is all i need is 100 rags, and they last for months, whats even better is, i got my own washing machine at the shop and i can have the guys wash the rags and keep them clean......  i wasent going to tell you ... but i guess i will...  sometimes.... i dont even wash the rags

We have tried to water prime and it does not work at all, here in the north country. Our mud is not very good for that sort of thing. If we do plug it has huge $$ backcharges attached to the plug, SO!!! we prime with Prime A Pak or Slick Pak operators choice.

 HI all   i still use cement to prime my m47 as i travel to diferent parts of the uk and i dont know the concrete suppliers normal mix as it varies a great deal in uk i always go for the tried and trusted cement option always cement on a pipe line and if no cement available ill use a slick pack never like just using water but each to their own. as one day sure enough you will have a problem with just using water and who wants to strip down a loaded boom .

Hey Art, I wish they had the same attitude here about wiping the pumps down on the jobs.  I do the same thing, but the customers like to bitch about it here in Atlanta.  Their whole attitude here is, its a concrete pump, its supposed to have conncrete on it.  That really pisses me off, lol.  The pump came to the job clean, it leaves clean.  They really hate it when you chip your hopper out on their clock.

I think it depends on the mix...I prime the same way as who does when I am in a my Scwing 47m I just cycle and spray redi-mix water up the material cylinders as the pump in in fwd. I have less water in the hopper and it slides right thru, as long as I'm A-framed. Now thats with Oregon Mud (best of the best, like butta') but with the Tx manufactured sand, crushed devil mix from hell, probably wouldn't try it.
