Description

How They Work

1. Suction Stroke: The diaphragm moves away from the fluid inlet, creating a vacuum and drawing fluid into the chamber.
2. Discharge Stroke: The diaphragm moves towards the fluid outlet, compressing the fluid and forcing it out of the chamber.

Types of Diaphragm Pumps

• Mechanical diaphragm pumps: The diaphragm is driven by a mechanical linkage.
• Pneumatic diaphragm pumps: The diaphragm is driven by compressed air.

Advantages of Diaphragm Pumps

• Self-priming: Can operate without a full suction line filled with liquid.
• Handles abrasive fluids: Can pump abrasive fluids without damaging the pump.
• Dry running capability: Can operate for short periods without damage when running dry.
• Gentle fluid handling: Minimal shear stress on the fluid, making them suitable for delicate fluids.
• Sanitary design: Easy to clean and sanitize, making them suitable for food and pharmaceutical applications.

Applications

• Chemical processing: For pumping corrosive and abrasive fluids.
• Food and beverage industry: For pumping delicate and viscous food products.
• Wastewater treatment: For pumping sludge and other viscous materials.
• Pharmaceutical industry: For handling delicate and viscous pharmaceutical products.
• Marine industry: For bilge pumping and other marine applications.
