Diaphragm pumps, also known as membrane pumps, are indispensable equipment in many industries due to their versatility, reliability and ability to handle aggressive, viscous or abrasive media. In this article, we will look at how diaphragm pumps are used in various industries, their advantages, specific examples of use, and highlight the expertise of Steiner, which offers diaphragm pumps under its own brand name.
What is a diaphragm pump?
A diaphragm pump is a positive displacement pump that operates on the principle of periodic compression and expansion of a flexible diaphragm, creating a pressure difference for pumping liquids or gases. Thanks to pneumatic or electric drive, such pumps are capable of operating without lubrication, which eliminates the risk of contamination of the working environment. According to manufacturers, the average service life of diaphragms is 15 million cycles, and for pumps made of fluoroplastic (PTFE) – from 3 to 30 million cycles, depending on the model.
Areas of application for diaphragm pumps
Diaphragm pumps are used in a variety of sectors due to their ability to pump liquids with a viscosity of up to 30,000 Stokes, which significantly exceeds the capabilities of centrifugal pumps (up to 1,000 Stokes). Here are the main industries and examples of their use:
- Chemical and petrochemical industry
Diaphragm pumps are ideal for working with aggressive media such as acids, alkalis, solvents and oil refining waste. For example, in the production of paints and varnishes, pumps transfer viscous pigment mixtures without disturbing their structure. It is estimated that 65% of chemical companies in Ukraine use diaphragm pumps to transport aggressive substances. - Food industry
In the food industry, diaphragm pumps are used to pump viscous products such as jams, nut pastes, oils or caramel. Their hygienic properties, confirmed by ATEX and IECEx standards, make them indispensable for the production of beverages and dairy products. For example, in juice production plants, pumps ensure accurate dosing of syrups. - Pharmaceutical industry
Due to the absence of lubrication, diaphragm pumps are used to transport clean liquids in the production of medicines. For example, the VP 30 pump with a capacity of 235 m³/h is used for vacuum filtration in laboratories. - Ceramic industry
Diaphragm pumps effectively pump ceramic slurries and varnishes, which are highly abrasive. Their ability to work with thick mixtures ensures the stability of the technological process. - Water treatment and wastewater treatment
In water treatment systems, membrane pumps are used to dose reagents such as coagulants or flocculants, ensuring effective water purification.
