Tuthill is up to something special that reaches far beyond manufacturing rock solid products. We inspire the hearts and souls of customers, families, and employees by being intentional about providing value in our products and in life.

We run rings around the competition

The SP100 is one of the most innovative designs for Air Operated Double Diaphragm Pumps in at least the last 20 years. Our patented, threaded ring construction means the SP100 can be serviced in half the time of competitor’s pumps, and since time is money, this represents tremendous savings to you over the life of the pump.


The SP100’s patented ceramic air valve delivers an extremely fast trip-over for far less pulsation than ordinary pumps. In fact, you may not need any aftermarket pulsation dampener saving you even more money. Plus, the SP100 improves efficiency by consuming 20% less compressed air, while at the same time, delivering a 15% higher flow rate than other AODD models of the same size.

 Our threaded ring and ceramic air valve designs make the SP100 the most advanced air operated double diaphragm pump on the market, leaving our competitors running around in circles trying to catch up!
