Key Features of the SANDPIPER S20 AODD Pump

• Corrosion-Resistant Materials: The SANDPIPER S20 AODD Pump is available in two durable materials—polypropylene and PVDF—ensuring enhanced chemical resistance. These materials make the pump ideal for the safe transfer of aggressive chemicals and fluids, even in harsh environments.
• Externally Serviceable Air Distribution System (ESADS+): The ESADS+ air distribution system is a standout feature, making the SANDPIPER S20 the only pump in its class with an externally serviceable ADS. This innovative design allows you to repair or clean the system in as little as five minutes, compared to 55 minutes for competitor models, reducing downtime and improving operational efficiency.
• Bolted Construction for Leak-Free Performance: The SANDPIPER S20 AODD Pump boasts a bolted construction with stainless steel fasteners for superior durability and leak-free performance. This construction ensures peace of mind, even in the most demanding applications, providing reliable operation and minimizing potential leaks.

Superior Serviceability and Simplicity

• Quick Maintenance & Reduced Downtime: The air distribution system (ADS) is one of the most commonly serviced components of any AODD pump. Thanks to the SANDPIPER ESADS+ feature, the ADS can be serviced without removing the pump from service, significantly reducing downtime and improving overall productivity.
• Interchangeable & Repairable Design: The original SANDPIPER ADS is fully interchangeable, repairable, and inline-serviceable, eliminating the common challenges of non-interchangeable ADS designs. These include compatibility issues, obsolete inventory, and higher maintenance costs, which are often found in pumps from other manufacturers.

Performance Guarantees

• Diaphragm Connecting Rod Guarantee: Ensures the reliable, long-term operation and performance of the diaphragm connecting rod, enhancing the overall lifespan of the pump.
• 5-Year Limited Product Warranty: Backed by a 5-year product warranty, the SANDPIPER S20 AODD Pump offers added confidence and security for your investment.
• Anti-Stall Air Valve Guarantee: This feature prevents air valve stalling, ensuring the SANDPIPER S20 operates consistently and reliably, even under demanding conditions.
