Function and structure of a laboratory diaphragm pump

A diaphragm pump is a type of positive displacement pump used to pump liquids or gases. The operation of a diaphragm pump is relatively simple. The pump consists of a housing with inlet and outlet ports and a flexible diaphragm inside the housing. When the drive is activated, a piston moves toward the diaphragm and compresses it.

This forces the medium through the outlet. As the piston moves back, it pulls air or the medium into the pump housing through the inlet. As soon as the movement of the piston is completed, the flexible diaphragm relaxes again and a negative pressure is created at its top. This process can be repeated continuously - each time the piston advances, fluid is delivered, and as it retracts, new material is added to be pumped.

Diaphragm metering pumps can meter very precisely because they have a control mechanism to ensure that only a certain amount is pumped per stroke at any given time (this is also called a metering stroke). This precision makes them ideal for applications such as chemical dosing systems in industrial plants or water treatment processes.

Diaphragm pumps for the laboratory: all applications

Diaphragm pumps are indispensable in many areas of the laboratory. They are used to pump liquids or gases and can have different characteristics depending on the area of application.

• In chemical analysis, for example, diaphragm pumps are used to extract samples from solvents or to separate reaction mixtures from solids by filtration.
• They also play an important role in the manufacture of medicines, where they are used to separate active ingredients from raw materials or to separate different components of a drug from one another.
• In addition to these classic areas of application, there are also numerous other possible uses for diaphragm pumps in the laboratory. For example, the devices are used to degas liquids or serve as vacuum generators when drying material samples.

Diaphragm pump types at a glance

Diaphragm pumps are widely used in industry for a variety of applications. There are several types of diaphragm pumps, which differ in terms of how they work and their range of applications.

 

Diaphragm vacuum pump

A diaphragm vacuum pump is a type of vacuum pump based on the movement of an elastic diaphragm. This pump works by alternating the pressure in an enclosed space to create a vacuum. The diaphragm is moved either mechanically or pneumatically . In the mechanical version, the diaphragm is driven by a piston, while in the pneumatic version, air pressure is used.

Diaphragm vacuum pumps are often used for applications where it is important that no oil or other liquids are allowed to enter the process. They are also very reliable and easy to maintain.

Piston Diaphragm Pump

This type of pump uses a piston to force the fluid through the diaphragm. These pumps are very efficient and can operate at high pressures.

Diaphragm diaphragm pump

Here, a flexible diaphragm is used to move the fluid. It is moved by an electric motor or pneumatic pressure on the back of the diaphragm.

Peristaltic diaphragm pump

A peristaltic diaphragm pump uses the effect of squeezing a flexible tube to deliver the medium from within.

Micro-metering pump

A micro-metering pump is a device that can meter tiny amounts of fluids in a precise and controlled manner. These pumps are used in many different applications, such as chemistry, biology, and medicine. The operation of a micro-metering pump is based on a piston or diaphragm principle.

The pump draws liquid from a reservoir and then dispenses it through a nozzle. In the process, the amount of liquid dispensed is controlled very precisely.

Micro-dispensing pumps are particularly useful in experiments involving small volumes, as well as in the preparation of preparations for medical purposes, where the highest accuracy is required.

Solenoid-driven diaphragm pumps

This type is ideal for aggressive media, as it has no direct contact with the pumped material.
