Quick installation tips bomba diaphragm pneumatics
In today's post, we have prepared some incredible tips for installing your pneumatic diaphragm pump, in order to reduce downtime and prevent some damage. Although these pumps are known for their versatility and durability, proper installation and maintenance is required.
Thinking about helping you increase the useful life and productivity of your pump, we've brought you these essential installation tips. See below!
Choose the correct position of your pump
The position of the pump is a determining factor in whether it delivers the expected productivity and durability. To do this, it is necessary to pay attention to some fundamental factors, which are:
- Suction lift: pneumatic diaphragm pumpss are self-priming, being able to pull at a height of up to 9.8 meters. Depending on the case, the pump must be positioned above the fluid, which will be drawn into the equipment. In these cases, it is ideal that the suction tube should be as short as possible. This way you reduce the stress on the pump diaphragm.
- Submerged suction: pneumatic diaphragm pumps They can act submerged in the fluid, but before that, it is essential that all materials and components are compatible with the fluid being pumped. Additionally, the pump exhaust must be located above the fluid level, ensuring that fragments larger than capacity do not enter the equipment.
- Flooded suction: in cases of submerged suction, there is fluid pressure entering the pump, with the center line being below the pumped fluid. In this scenario, the pump must be as close as possible to the fluid reservoir, in order to reduce the length of the suction line. Remember to check the pressure of the fluid entering the pump, which must be less than 10' NPSHA pressure. To calculate this pressure (NPSHA = absolute pressure – vapor pressure + static load – friction), you need to know:
- The absolute pressure on or at the surface of the fluid;
- Static head (the vertical distance from the top of the surface to the impeller eye or the pump centerline, when equivalent);
- Vapor pressure of the pumped fluid;
- Friction head.
Proper size of pump connections
All piping and accessories used for fluid inlet and outlet must be proportional to the size of the pump. For example: if you are using a 2” pump, the piping used must be 2” or larger. When the tubing is smaller, fluid circulation will be restricted, reducing the durability and flow efficiency of the diaphragm.
Compressed air filtration and regulation
Air quality is one of the aspects that most affects the durability of the bomba. Generally, the air that is expelled by air compressors is dirty and unregulated, which can damage and impair the useful life of your pump. For this reason, this air must be filtered and regulated, which will provide regular and efficient operation.
Air filters/regulators play a fundamental role in the performance of pneumatic diaphragm pumps, ensuring that there is more control and precision in the removal of contaminating agents (liquids or solids), while at the same time controlling the air flow. This means you can count on a controlled pressure of clean air, reducing downtime due to damage and the need for extra maintenance.
If you do not control the pressure and air volume, you can harm the efficiency of your pump, in addition to reducing its durability due to overpressurization, unnecessary cycles and impaired starts.
