Check them out, nice pump

Very nice machine must be stroking it hard lots of boom bounce

yeah....the putz beside around at 3:00 on the video...scary how it bounce like hell....the DY seem pretty much nice machine....

the putz has a 4" hose on must be the topping pump , is why its bouncing more.

I was the operator on the DY pump and was very impressed with its smoothness pumping at full volume. The Putzmeister was definitely using a 5" hose that day and definitely had more boom bounce. Big volume pours always get the big hoses. 

you are right on the 5" , my bad I thought I saw a reducer on the putz.
