For more than 55 years, manufacturers across multiple industries that involve hazardous materials have trusted SANDPIPER to protect people, equipment, the environment and the material being pumped.
The SANDPIPER ST1 AODD pump provides unsurpassed fluid containment in the event a diaphragm is breached. This leak-free pump is designed to be driven by compressed air or nitrogen.
Environmental concerns: When fluids (like those listed below) escape to the environment, significant time and effort is required on clean up and material recovery. Additionally, the costs of downtime, lost production, manpower, equipment replacement, disposal fees and fines can be excessive. Preventing leaks when handling these substances provides a more efficient operation and avoids the damaging effects of environmental and human exposure to these toxic fluids.
High cost of lost fluid: When fluids (like those listed below) escape to the environment, the cost of losing them is significant. Lost fluid means lost profit.
Fluids that need to be contained: Even non-toxic fluids, like clean water, can create hazards, annoyances and safety concerns if people are in or around the area surrounding a pump when a diaphragm fails. When dealing with toxic and hazardous fluids, the need to contain leaks goes from a nuisance to a critical safety need.
To determine chemical compatibility with this pump, please refer to our Chemical Compatibility Guide. Material of construction options include: aluminum, stainless steel and Alloy C, with elastomer TPE (thermoplastic elastomers) and PTFE options in diaphragms and check valves.
