Description Product

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 S20 Non-Metallic 2" AODD Pump provides unsurpassed fluid containment in the event a diaphragm is breached.

TYPICAL PUMP VERSUS CONTAINMENT-DUTY PUMP

In a typical AODD pump, when the pumping diaphragm is breached, the fluid enters the air distribution system and escapes into the environment through the muffler, requiring immediate service.

In a containment-duty pump, when the pumping diaphragm is breached, the fluid enters the containment chamber and visual indicator sight tubes, alerting the user. The fluid is fully contained so the pump can continue running until the operation is complete or maintenance can be scheduled.

This leak-free pump is designed to be driven by compressed air or nitrogen.

S20 CONTAINMENT-DUTY PUMP FEATURES

• Leak detection: All containment-duty pumps are designed to accommodate visual, mechanical and electronic leak detection devices.
• Durability: The durable, bolted construction of the S20 is superior to the clamped-band construction pump, providing exceptional leak-free performance.
• Serviceability: The air distribution system (ADS) is one of the most frequently serviced parts of any AODD pump. Only SANDPIPER's ESADS+ feature allows access to the complete ADS without removing the pump from service. Repair or clean in five minutes (versus 55 minutes for competitors). Additionally, the S20 offers air-side interchangeability with SANDPIPER’s 1" (S1F), 1½" (S15) and 3" (S30) pumps for reduced inventory costs.
• Trusted design: SANDPIPER’s original ADS is fully interchangeable, repairable and inline-serviceable. Other manufacturers frequently change ADS designs, creating issues with interchangeability, obsolete inventory and increased cost of ownership.
