The simplehuman stainless steel pulse pump is engineered from the inside out. Its innovative design includes a large pump tube that allows for greater soap or sanitizer flow – no matter how thick – with far less effort. Ball bearings located at the top and bottom of the pump keep air from entering, which prevents soap from dripping, leaking or drying out. Just a light touch on the spout provides a generous portion of soap – and it’s designed to last more than 150,000 pumps – that’s over 15 pumps a day for 27 years. Fast, neat and nearly effortless, it is a uniquely satisfying experience.
