Diaphragm pumps

There are various types of diaphragm pumps, primarily distinguished by the materials from which they are made. Each type of pump has its own unique characteristics and advantages, with the chemical resistance of the materials playing a significant role. Factors such as gas type, flow rates, temperature, and pressure also play a role in the selection process.

Diaphragm pumps are used in laboratory applications such as rotary evaporation, filtration, distillation, central vacuum systems, and other laboratory equipment. These pumps are known for their long lifespan, relatively simple maintenance, and chemical resistance. The capacity and ultimate vacuum of a diaphragm pump depend on the number of diaphragm stages in the pump. A diaphragm pump can be configured with a maximum capacity of approximately 10 m³/h and an ultimate vacuum of around 1 mbar.

Diaphragm pumps: the ideal solution for various processes

A diaphragm pump is a versatile and reliable vacuum pump widely used across multiple industries. Whether in laboratories, chemical processes, or medical applications, diaphragm pumps are renowned for their chemical resistance, ease of use, and long lifespan. In this article, we answer important questions about diaphragm pumps and explain why they can be a valuable asset to your processes.

What is a diaphragm pump?

A diaphragm pump is a type of vacuum pump that operates through a flexible diaphragm performing a controlled suction and discharge motion. This process is entirely oil-free, making diaphragm pumps particularly suitable for applications requiring purity and chemical compatibility.

The operation consists of two phases:

  • Suction phase: The diaphragm retracts, creating a vacuum that draws air or gas through an inlet valve.
  • Discharge phase: The diaphragm moves forward, pushing the contents out through an outlet valve.

This simple yet effective mechanism ensures reliable performance with minimal moving parts, resulting in a long lifespan and low maintenance requirements.

The advantages of a diaphragm pump

Diaphragm pumps offer several benefits that set them apart from other vacuum pumps:

  • Chemical resistance: Manufactured with high-quality materials resistant to corrosive gases and liquids.
  • Low maintenance: The robust design and absence of oil-lubricated components minimize wear and tear.
  • Suitable for liquid transfer: Can handle small amounts of liquid without sustaining damage.
  • Environmentally friendly: Their oil-free operation contributes to a cleaner environment and lower operational costs.

Applications of diaphragm pumps

The versatility of diaphragm pumps makes them suitable for a wide range of applications, including:

  • Laboratories: For processes such as rotary evaporation, filtration, distillation, and other analytical applications.
  • Medical technology: For precise air and gas displacement in sensitive equipment.
  • Chemical processes: For transferring reactive gases and liquids without risk of corrosion or contamination.
  • Central vacuum systems: For use in academic and industrial settings requiring continuous vacuum.

With capacities up to 10 m³/h and an ultimate vacuum of approximately 1 mbar, diaphragm pumps are flexible for both standard applications and customized processes.

How a diaphragm pump enhances efficiency

In addition to technical advantages, diaphragm pumps are highly cost-effective. Their design minimizes energy consumption and maximizes performance, leading to lower operational costs. Their longer lifespan compared to many other pump types ensures an excellent return on investment. Another notable feature is their quiet operation, making diaphragm pumps ideal for laboratories and other noise-sensitive environments.
