Product Overview
The Sandpiper S20 2” Polypropylene Containment-Duty Ball Valve AODD Pump is a non-metallic air operated double diaphragm pump designed for chemical transfer, bulk transfer, and a wide variety of process applications. Built with corrosion-resistant polypropylene construction, this pump is suitable for handling aggressive fluids where chemical compatibility, durability, and reliable transfer performance are important.
The S20 features a rugged, time-tested design with three-piece bolted manifolds that allow the porting connections to be reoriented to suit different process requirements. Its 2” universal flange connection fits both ANSI and DIN flange standards, making it flexible for industrial installation.
Designed with Sandpiper’s ESADS+ air distribution system, the S20 allows access to the complete air distribution system without removing the pump from service. This helps simplify maintenance, reduce downtime, and support long-term reliability in demanding chemical transfer applications.
