Who are they? A bit of a backstory… In 1955, one man revolutionized the pumping industry when he invented the air-operated double diaphragm (AODD) pump.
The epiphany began in 1955 when a large water pipe ruptured several feet below ground, flooding a shop at a steel factory. Amid the bedlam, a cool-headed foreman surveyed the inundated workshop and drenched workmen and yelled out to “Slim,” Jim’s nickname, “Hey, Slim, you would make a million dollars if you could invent a pump to get this stuff out of here.” And thus history was set in motion, changing the landscape of industrial and commercial processes forever.
Remember: there are many AODD pumps on the market that strive to be Wilden – but only one market leader.
