The IMER Booster 20 is the most compact towable high performance concrete pump available anywhere on the market today. The diesel powered swing tube S valve, Booster 20 is designed to pump up to 1" aggregate concrete through 4" pipe or hose. Its compact size makes the Booster able to function in limited space jobsite areas where no other pumps of its capability could fit. Super affordable, costing thousands less than competitors pumps, the Booster 20 can do a variety of jobs including shotcrete. Anyone in the market for a small concrete line pump would be foolish not to thoroughly look at the Booster 20 and it's capabilities.
