Frequently Asked Questions 

What is a pneumatic double diaphragm pump, and how does it work?

A pneumatic double diaphragm pump is a type of positive displacement pump that uses compressed air as its power source. It typically consists of two flexible diaphragms connected by a shaft. Fluid enters the pump chamber through the vacuum created when compressed air is applied to one side of the diaphragm, causing it to bend inward. Simultaneously, the other diaphragm flexes outward, pushing the fluid out of the chamber. This alternating action creates a pulsating flow, making it suitable for handling viscous or abrasive fluids.

What are the advantages of using a pneumatic double diaphragm pump?

These double diaphragm pumps offer several advantages, including:

Self-priming capability: These pumps can automatically prime themselves, even when dry or with suction lift conditions, which eliminates the need for manual priming.

Versatility: They can handle a wide range of fluids, including corrosive, abrasive, and viscous substances, making them suitable for various industrial applications.

Dry-running capability: Unlike some other pump types, pneumatic double diaphragm pumps can run dry without causing damage to the pump.

Simple design: With fewer moving parts and easy maintenance requirements, these pumps offer reliability and longevity.

Variable flow and pressure: Adjusting the air pressure can control the flow rate and discharge pressure, providing flexibility in operation.

What are the typical applications of pneumatic double diaphragm pumps?

These double diaphragm pumps find applications across various industries, including:

Chemical processing: Handling acids, solvents, and other corrosive chemicals.

Oil and gas: Transferring crude oil, drilling mud, and wastewater.

Food and beverage: Pumping syrups, sauces, and other viscous food products.

Pharmaceuticals: Transferring pharmaceutical ingredients and formulations.

Mining: Handling slurries, tailings, and dewatering applications.

Water treatment: Pumping wastewater, sludge, and chemical additives.

How do I select the right pneumatic double diaphragm pump for my application?

When choosing a pneumatic double diaphragm pump, consider the following factors:

Fluid compatibility: Ensure that the materials of construction are compatible with the fluid being pumped to prevent corrosion or contamination.

Flow rate and pressure requirements: Determine the desired flow rate and discharge pressure needed for your application.

Viscosity and solids content: Consider the viscosity and presence of solids in the fluid to select a pump with the appropriate diaphragm and valve materials.

Suction lift and discharge head: Evaluate the suction lift (vertical distance from the liquid source to the pump) and discharge head (vertical distance to the discharge point) to ensure adequate pump performance.

Operating environment: Take into account factors such as temperature, humidity, and potential exposure to harsh chemicals or abrasive materials.

What maintenance is required for pneumatic double diaphragm pumps?

Regular maintenance is essential to ensure the continued performance and longevity of these double diaphragm pumps. Maintenance tasks may include:

• Inspecting and replacing diaphragms, valves, and seals as needed to prevent leaks and maintain efficiency.

• Always prefer to lubricate moving parts and must inspect for signs like wear or damage. 

• Cleaning pump components and removing any accumulated debris or contaminants.

• Checking and adjusting air pressure settings to optimize pump performance.

• Performing routine inspections and preventive maintenance according to the manufacturer's recommendations.

How can I optimize the performance of a pneumatic double diaphragm pump?
