Recently, Odessa Pumps was contacted by a large composite pipe company that was having failures with their existing air-operated double diaphragm (AODD) pumps. This customer originally had a pump service life of approximately 1 year before experiencing a diaphragm failure, but they had seen that service life drop to 6 months and then to 3 months. Odessa Pumps teamed up with Sandpiper to support the customer and resolve the shortened diaphragm life problem.
Odessa Pumps and Sandpiper conducted a site audit with the customer and concluded that the overall pump system was set up adequately for their application. When the audit’s focus turned to the pump itself, we found that the existing AODD pump’s design had a single PTFE diaphragm, which is highly chemical resistant but susceptible to material fatigue, leading to shortened diaphragm life compared to other materials.
Our recommendation was to replace the current AODD pumps with a Sandpiper model designed with a double-layered PTFE diaphragm and Santoprene® TPV backing for additional durability. Since replacing their pumps, the customer has seen their 3-month service life improve to nearly 2 years of service without a diaphragm failure. They have since ordered an additional 2 Sandpiper pumps to replace their other AODD units.
