Reconditioned Mayco ST30 concrete line pump. Diesel engine always starts immediately. No issues. Works great. Will come with over 100’ of hose sections, various sized clamps, line reducers etc. with the hose size we’re using 3/4 aggregate in the concrete is about the largest you can use. Works best with 1/2” minus. Fittings available for larger diameter hose if you needed to enlarge. Probably easiest to simply call me for more details.
