Built another custom pump

Been awhile since I was here, bought a transcrete trailer pump from a member here a year ago, plan was to build the tiniest mobile pump ever. I cut down a Isuzu NPR that has a 4 banger turbo Diesel with Allison auto and overdrive. Pulled 4' out of the chassis and moved rear end forward as much as possible. Cut off all the trailer junk and added 4" frame tubing underneath to get a bit higher to be able to run hydraulics and hopper at an easy angle for trucks to back up to. So the wheelbase is now 10', fits anywhere, you can Uturn on residential streets, can't feel the weight of the pump even if hoppers full. So easy to set up and break down. I never want to drive any of my big pumps ever again. Never ever never. Oh and fuel consumption is a joke now, I can go all week without filling pump or truck. Paint is almost finished, top gets the black treatment. Oh pump fits in a normal residential garage as well. I might just start building tiny pumps for a living

Took 2 weeks and had my eye drilled to remove metal. Some real fun

your hopper is too high off the ground. 

i have trouble with a volmetric conveyor being tilted too high just for my trailer

My hopper is to high?!? It's 4' that would mean all my other pumps are wrong, everyone else's too

Great job! Thanks for sharing the photos.

There are a few mechanics left here.. I've considered this option but still pulling a trailer. I like your choice of truck.

Do you have an air system for blowing hose? What about water?

barron 10-23-2016 reply profile send pm notify

These transcrete pumps have tiny hoppers, super easy to clean. If you stroke enough air at the end of the job, I can suck a ball back though 150' of 2 1/2" line and only have half a hopper left. Cleans fast with little water. This pump I've added 30 gallons of water but rarely use it, alway beg water from the mixers. My schwing hopper on the other hand holds a quarter yard and is a complete pain in the ass to take down. I get suicidal after putting all those reducers on then breaking them down several times a day.

just enough bed to carry the hoses is good and the dump bin for the stuff holds the most amount

How do you propel your water? Air tank or mechanical?

Screw all those reducers Barron. Around here you can use a HD 5" to 3" reducing elbow right off your assend. Concrete actually reduces easier through an elbow.

Alto, I use air, keep small inflator in the cab and charge to 80psi

hi TooTall, long time. I've tried the 5/3 elbow, likes to try and plug. 10" cylinders and 6' stroke is to fast in my experience, although Cadman's pump mixes are almost unpumpable now. Fractured rock and homemade sand

To Too Tall I wouldn't mind getting rid of my heavy and award 5to 3 reducer and trade for a reducer Elbow how do you know it mixes easier?

pudg2 11-07-2016 reply profile send pm notify

we use the 5-3 elbow and we never have issues , but I am not dealing with manufactured sand or fractured rock

I bought a 5-3 reducing elbow, trying it out today,  I'm pumping a small rock mix through 2" hose. 

Sounds like a good idea! (Todd the choose photo option isn't working?)

It worked just fine! Good idea

Hi Brian does it seem easier to handle? Every little bit helps. Terry

b-alto 11-13-2016 reply profile send pm notify

Hey Terry, It pumped just fine 3/4" minus mud. I didn't have to use the 4"-3" reducer and 4" clamp. Yeah eliminating a reducer is nice!
