ST1½ & ST40 – Metallic Containment-Duty AODD Pump

Sandpiper’s ST1 1/2 & ST40 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 Sandpiper Containment Duty Ball Valve Pumps are constructed of materials such as Aluminum, Stainless Steel and Alloy C, with elastomer TPE (thermal plastic 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 fluids that are considered important to the products escape to the environment the cost of these loss 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 working around the area surrounding the pump should a diaphragm fails. The Containment Duty Pump is able to prevent all 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 diaphragm pump will be able to maintain its operations until the end of the processing time or until its scheduled maintenance.
