Diaphragm air pumps
The price of a diaphragm air pump is not very high, but a compressor will be required to put the unit into operation. It is not powered by an electric motor - its functionality is realized by compressed air pressure. The air stream of the compressor is pumped through the hose into the pump causing an oscillating motion of the membrane. The latter pushes the working fluid in the right direction. Diaphragm pumps are capable of pumping liquids that simple centrifugal units cannot handle. These are media of increased viscosity, aggressiveness, having solid components in their composition.
The scope of application of diaphragm air pumps
| Industry | Using |
|---|---|
| Petrochemical and chemical industry | An industry where a diaphragm air pump is actively used for acids, alkalis and various solvents. Pumps suspensions, oil refining waste, adhesives, lubricants, etc. |
| Food industry | It is used as a filter press in brewing industries, on technological lines of oil processing, for pumping caramel and media with solid inclusions |
| Ceramic | It is used for pumping clay solutions, varnishes and glazes. Provides pumping of mine waters. |
| Paint and varnish | Provides explosion-proof pumping of highly flammable grout and varnishes |
| Glass | Pumping of polishing pastes and waste water |
How does a pneumatic diaphragm pump work?
The pneumatic diaphragm pump consists of a centrally located coaxial air unit and latest generation membranes connected to the shaft. On each side of the housing there are ball valves with seats on the outlet and receiving nozzles. The principle of operation of the membrane unit is as follows:
- The membrane creates a pressure vacuum;
- Liquid is being sucked in;
- After oscillation, the coaxial heat exchanger directs compressed air towards the opposite membrane;
- The cycle repeats.
Types of diaphragm air pumps
If you are looking for a diaphragm air pump for oil or other viscous liquid, pay attention to the products of the Italian company Debem. For more than 30 years, working according to its profile, the company has been leading the high-tech technology markets, creating pumping units of tomorrow. Debem designers have created 2 series of diaphragm pumps:
- CUBIC - compact in size, with a capacity of up to 17 l/min. They have a double membrane and the possibility of dry suction to impressive heights. Practice has shown the ability of the unit for long-term operation without breakdowns and accidents;
- BOXER is a popular series that has found applications in the field of water treatment, mechanical engineering, chemical industry, printing, paint and varnish production and other industries. The pumps are distinguished by their high production capacity - up to 850 l/min.
