Sandpiper’s ST1 & St25 Metallic Containment Duty AODD Pumps were designed to handle highly corrosive and hazardous chemical fluid requirements. This series of air-operated double diaphragm pumps are designed with containment chambers, hydraulically balanced/coupled pumping diaphragm and driver diaphragm assemblies. The containment chambers are designed to accommodate visual, mechanical and low-voltage leak detection devices. The Containment Duty Pumps are constructed of materials such as Aluminum, Stainless Steel and Alloy C, with elastomer TPE (thermoplastic elastomers) and PTFE options in diaphragms and check valves.
Why use containment duty pumps?
Due to environmental concerns regarding corrosive or hazardous fluids escaping into the environment, a large portion of the time is required to clean up and recover lost materials. On top of the concerns, there will be the costs of downtime, lost productions, manpower, equipment replacement, disposal fees and fines can be excessive. Prevention of these leaks whilst handling these fluids allows for a more efficient operation and avoids the damaging effect of these toxic fluids’ exposure towards the people and the environment.
When the fluids that are considered important to the products escape to the environment the cost of these losses are significant as it’s considered losing profit. Even non-toxic fluids such as water can create a hazardous environment towards the safety of the people should a diaphragm fails. The Sandpiper Containment Duty Ball Valve Pump is able to prevent these losses through its system by redirecting the fluid that breached the diaphragm towards a containment chamber that alerts its users through a visual indicator. The pump will be able to maintain its operations until the end of the processing time or the scheduled maintenance.
