Optimized for efficient dishwashing with a caddy that perfectly fits the pump and stores a sponge so it's always at your fingertips, our 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. A wide funnel opening makes refills quick, easy and mess-free. simplehuman
