Standard Duty Diaphragm Pumps, Metallic & Non-Metallic

Designed for High Efficiency in Standard Duty Applications SANDPIPER’s Standard Duty diaphragm pumps offer a balanced solution for operations that require reliable fluid handling without excessive energy use or maintenance demands. These air-operated double-diaphragm (AODD) pumps are designed to move chemicals, water, and other industrial fluids efficiently across a wide range of general-purpose and bulk transfer applications. Both the S20 (2") and S30 (3") models feature an upgraded design that builds on proven performance. Engineered for higher flow and enhanced durability, these pumps help streamline operations and reduce long-term operating costs. Key Features: • Sizes: 1/4" – 4" sizes (6 – 100 mm) • Flow: 0 – 285 gpm (0 – 1,078 lpm) • Solids Handling: Up to 0.875" (22 mm) • Construction (Metallic): Aluminum, Stainless Steel, Cast Iron • Construction (Non-Metallic): Polypropylene, PVDF • Elastomers: Nitrile, Neoprene, Santoprene®, PTFE, Fluorocarbon, Hytrel®, EPDM • ESADS+Plus air distribution system allows easy in-line maintenance • Polypropylene center section on S30 Non-Metallic to reduce corrosion and weight • Redesigned manifold with fewer leak points and upgraded mounting components
