Hi,

I am concerned about the wear on my machine. 1,250 yds, schwing p305... had a seal fail, and supposedly ruined my transition tube main shaft. Manufacture is going to sub. for warr. even though pump is no longer covered (happy part). Sad part. Is this whats to be expected, i.e. "normal wear". Cutting ring and plate are worn, but ok. Material clys. still good. just changed mud cups. Should the "hard" parts wear this quickly. I am wondering if my machine is too light duty for my pumping. Mostly 3/4" 6 sk. blend mixes. hardly any 3/8". Any experience with this manufacture or similar small line t-tube pumps? Figured the ratio @ about $2/yd. Yds/cost of reapirs?

Obviously this site and the so called "experienced" persons responding are not worth my time.

Redman, i am sorry that nobody is being very helpful, I will look into this and get you some help on the hows, whats, and whys. I know you cant go wrong buying a schwing they are very good pumps. Give me a day or so and we can get you some help.

Todd.

Redman1, It's not uncommon for some of the parts to wear sooner on the smaller pumps. Like all of the line pumps, maitenance is key, and grease is cheap. I have talked with other pumpers that grease the pivot shaft a little every load! This is not a bad idea. Once you see grout oozing out the back, over-grease until you can repair the problem.

1. You have not said what the specific problem is

2. Is that machine the best for your application

3. You can get pissed off and walk; but you still have the problem

4. Many has, as far as I, and lots of others, nailed your problem, and you just do not want to hear it.

5. If you are going to be in this business you had better develop a sense of humor; and the ability to turn it at your self. 

6. NO, THAT IS NOT TYPICAL. Your cost per yard is many, many times what it should be.

Hey guys, thanks for helping out redman, we all know how tight money is and when your source of income goes down it makes you a bit upset. I hope these last few post have helped and we hope you let us know how it goes.

I am not hard headed and do "hear" what you are saying. I grease that shaft right after every job. I had not been greasing it during long pours. Maybe that was the prob. The manf. said it was not a lack of grease issue... which prompted the warr. coverage. The seals did not fail, rubber intact, looked almost new. The shaft wore thin and the seal wouldn't fit properly. The tech told me he had never seen it on any of their pumps. At any rate, prob. fixed and thanks for sharing the experiences. I do have a sense of humor... and I understood the puns. Thanks again Art, Many, Todd, and Slanderson...

Redman, I have the same pump. I like it, but most the pours I do with are under 50 cu yds. I use 2.5" hose and 3/4" rock. I like the pump because it is light. I have not yet had complaints of being too slow. I pull it with a 1/2 to pickup,throw my hoses right on top of the machine. Bring a little water for wash out and thats all I need. The wear parts should last just like the bigger pumps. I took my rear S-tube bushing out and cleaned,it wasn't getting grease. I have 500 hrs and still on the same parts. My competition bought a 750. I think its over kill. I have a boom truck for big pours.
