A bomba diaphragm pneumatics is a kind of positive displacement pump which works using compressed air, that is, without the need for electrical energy to pump. To make this possible, it uses a pneumatic valve known as a diaphragm that directs compressed air as the pump operates.
Thanks to their functionality and versatility, pneumatic diaphragm pumps can pump liquids with different viscosity levels and suspended consoles, allowing their application in different types of operations and in different industries. O seu design simplificado e os incorporation materials they also allow the safe pumping of abrasive fluids and chemicals, preventing leaks and ensuring even more efficient operation.
What are the components of pneumatic diaphragm pump?
To be able to pump fluids efficiently, the pneumatic diaphragm pump depends on some essential components, as we will see below:
- Fluid chamber: the main function of the fluid chamber is to store the volumes of fluid that are aspirated and pumped. Depending on your pump model, these cameras also include a ball housing store that functions as a check valve.
- Central Structure: the central structure of your pneumatic diaphragm pump includes the air inlet and outlet that is supplied by the pneumatic exchanger, and is responsible for the air pressure necessary for the pump to operate.
- Air valve: the air valve is responsible for directing compressed air directly to the fluid chambers and testing the membranes of the pneumatic diaphragm pump.
- Collectors: attached to the external cameras to provide sealing, the collectors are part of the connection interface of your pump system.
- Diaphragms: the diaphragm is the most important structure of your pump, and can be found in different materials and designs. They function both as a sealing barrier to separate the fluid from the dry part of the pump and also to pump this same fluid.
How the pneumatic pump works in practice
Now that we understand what the main components of the pneumatic diaphragm pump are and how they are part of the structure of your equipment, we can understand how it works. The operating cycle of the pneumatic diaphragm pump is based on the use of compressed air to drive the equipment, using two flexible membranes mounted on a shaft that, when moving back and forth, pump fluids in and out of the fluid chamber.
The cycle of your pneumatic diaphragm pump is separated into three distinct phases:
Phase 1: In the first stage, the air passes through the hole in the pump body and reaches the central ring, where the diaphragm, when driven by air pressure, moves the liquid into the collector.
Stage 2: In the second stage, the pump spool crosses the opposite side of the pneumatic exchanger and slides along the shaft, sending the other air chamber with compressed air pressure.
Phase 3: in the discharge phase, the air chamber that was under previous pressure now finds an open passage. In this way, the pull of the opposite membrane retracts while creating a vacuum, allowing fluid to rise and fill the chamber.
Pneumatic diaphragm pumps are highly versatile equipment that can be implemented to pump different types of fluid. For this reason, before choosing pumping equipment for your industry, check which pneumatic diaphragm pump can be implemented in your operation and what benefits it can deliver to your industry.
One of the biggest advantages of this equipment is that it has a self-priming function and can be positioned above the fluid level and suck it up even when running dry. It can also be installed submerged, especially in well emptying operations. Its versatility demonstrates that it is an extremely practical and cost-effective piece of equipment, in addition to having a low acquisition cost.
