Introduction

Pneumatic double diaphragm pumps are highly versatile and efficient devices utilized across various industries for fluid handling. Their design enables them to handle a wide range of fluid types, including those that contain solids, are viscous, or have abrasive properties. These pumps operate using compressed air, making them suitable for both indoor and outdoor applications.

Mechanics and Design of Pneumatic Double Diaphragm Pumps

The operation of a pneumatic double diaphragm pump is centered around two flexible diaphragms. These are moved by air pressure alternately to create a pumping action. Each diaphragm is connected to a common shaft, and as the air fills the chamber on one side, it pushes the liquid out of the pump chamber. When the cycle reverses, the other diaphragm is activated.

Major parameters include:

• Flow rates: Typically range from 0.5 to 300 gallons per minute (GPM).
• Pressure range: Operable with air pressures from 20 to 120 psi.
• Temperature tolerance: Can handle fluids ranging from -40°F to 250°F.
• Suction lift: Effective up to 25 ft when primed.

Applications of Pneumatic Double Diaphragm Pumps

Widely applicable in sectors such as chemical processing, food and beverage, pharmaceuticals, and mining, these pumps are reliable for transferring:

• Corrosive chemicals that require specialized materials.
• Viscous materials like oils and adhesives.
• Abrasive slurries and fluids containing solids.
• Shear-sensitive materials, ensuring no degradation in the fluid properties.
