Deskripsi
Product Overview
The Sandpiper S20 2” PVDF Containment-Duty Ball Valve AODD Pump is designed for hazardous, corrosive, and dangerous fluid transfer where safety, leak containment, and chemical resistance are critical. Built with non-metallic PVDF construction, this air operated double diaphragm pump is suitable for aggressive chemical handling, acids, caustics, corrosives, contaminated water, wastewater, and other fluids that must be safely contained.
Unlike a typical AODD pump, the S20 containment-duty design helps contain fluid in the event of a diaphragm breach. Fluid enters the containment chamber and visual indicator sight tubes, alerting the user while keeping the pumped fluid contained until operation can be completed or maintenance can be scheduled.
With durable bolted construction, ESADS+ air distribution system, and compatibility with visual, mechanical, and electronic leak detection devices, the S20 PVDF containment-duty pump helps protect people, equipment, the environment, and valuable process fluids.
