Rice model ST-1, serial #0024, built and sold in Feb 1977, still in Rainbow’s rental fleet in June of 2002….

“It was quite a surprise to find we had one of the original RICE Hydrostatic Test Pumps in our rental fleet. This machine has been a reliable performer over the years, with no major breakdowns. Our test pumps normally pay for themselves 3 – 4 times each year. We have several in our fleet now. RICE test pumps are the only brand that we would consider buying, as we appreciate the dependability of quality machines.”
