Frequently Asked Questions (FAQs)

What is a diaphragm pump?

A diaphragm pump is a type of positive displacement pump that uses a flexible diaphragm and check valves to move fluids. It is driven either by compressed air or electricity and is known for handling a wide range of fluids, including corrosive, viscous, or abrasive materials.

When to use a diaphragm pump?

Diaphragm pumps are ideal when handling aggressive, viscous, or solid-laden fluids. They are commonly used in industries such as chemical processing, food and beverage, mining, and wastewater treatment. They are suitable for applications requiring chemical resistance, dry-run capability, and low maintenance.

What is the difference between a diaphragm pump and a bilge pump?

A diaphragm pump uses a reciprocating diaphragm to move fluid, making it suitable for handling corrosive or abrasive liquids. A bilge pump, typically found in boats, is designed to remove excess water and is usually centrifugal or impeller-based. Diaphragm pumps are more versatile in industrial applications.

What is a double diaphragm pump used for?

A double diaphragm pump is used for transferring, dosing, or metering fluids that are abrasive, viscous, or chemically aggressive. It offers smooth and consistent flow, is self-priming, and can run dry without damage, making it ideal for demanding industrial environments.

What is the difference between single and double diaphragm pumps?

A single diaphragm pump uses one diaphragm and is typically suitable for lighter-duty applications. A double diaphragm pump has two diaphragms working alternately, providing more balanced pressure, smoother flow, and improved handling of thicker or more challenging fluids.

What kinds of fluid can a double diaphragm pump deliver?

Double diaphragm pumps can handle a wide variety of fluids, including water, chemicals, oils, slurries, solvents, adhesives, paints, and even fluids containing solids. Their strong chemical resistance and design flexibility make them suitable for use in many industrial sectors.
