Polypropylene Air operated diaphragm pumps are designed for Acidic and Flammable Media use. Polypropylene Diaphragm Pump can easily pump from clean, light Acidic viscosity fluids to corrosive, abrasive medium viscosity fluids and can transfer large particles without damage. Due to their pneumatic motor, they could be used in potentially explosive areas. PP Air Operated Double Diaphragm Pumps can run with a continuous supply of compressed air. Polypropylene Diaphragm Pumps can be versatile enough to help provide dewatering functions or transfer weak acids from storage Barrel or Drums. PP AODD Pumps are lightweight, can be easily transported where needed, and equipped with a pneumatic operation to reduce exhaust and spark hazards. PP AODD Pumps are Self-priming Pumps and are capable of Dry Running. Numatic Pumps AODD Pumps are of a bolted type and offer a number of advantages that make them perfect for an almost endless variety of uses. PP Air Operated Double Diaphragm Pumps are air operated, they are used in Hazardous, Acidic and Flammable areas.
