This cute little pump is powerful enough to quickly inflate the YBR® balls, yet it takes up little space in your overnight bag, so it’s easy to do YBR® when you travel. THE YAMUNA® PUMP is small and yet powerful enough to inflate these dense PVC plastic balls. Many pumps we had to throw out along the way that would just break from inflating these balls. This pump is easy to travel with, takes up practically no space, and by the way all balls are shipped deflated except for the black balls and Face balls. Please note: when ordering any ball from this website, know that the Pump we sell has been carefully selected to work optimally with these balls. While many standard sport pumps with a “basketball” needle will work, many do not, and in some cases damage the nozzle of the balls. A ball can last a very long time if well cared for. Our pump is portable, lightweight, and the needle is removable so you can deflate your ball. We recommend it highly. In addition, take care when inserting a needle into Yamuna balls. We recommend you moisten the needle and twist as you insert or remove – do not force, and do not over-inflate. The first time you inflate your ball, do so until the slight bulge begins to disappear. It may not disappear entirely at first, but will do so after a few uses. Note: Do not insert needle into the back bulb of the pump as this will damage it
