Rotary lobby pumps are equipment that have a more limited compatibility with fluids and greater sensitivity. This is due to its more complex conception that, while allowing it to be employed in many applications, has characteristics that make it a riskier choice.
With a higher maintenance cost than a bomba pneumatic diaphragm pumps, rotary lobe pumps can also be used in a wide variety of industries and segments, equally resistant to high temperatures. However, comparison with other factors shows that this equipment has many disadvantages, especially when compared with pneumatic diaphragm pumps.
Maintenance process
Its main disadvantage is the possibility of unexpected stops with an expensive maintenance process (in some cases the product replacement may be required).
Reduced elevation with thinner liquids
In the case of liquid pumping Thin, rotary lobe pumps may not be the best solution for the industry. Its pumping will vary according to liquid viscosity and applied pressure. Since this equipment does not deal with this type of fluid efficiently, it may not be the best solution for industries dealing with this material.
Repair cost
In their composition, the rotary lobe pumps have several rotating pieces that are more expensive in their manufacture and maintenance. To work, it also needs more expensive and delicate seals, which can compromise the process because of the leaks.
Due to the sensitivity of their parts, rotary lobe pumps have the highest maintenance cost.
Higher investment cost
Comparing this bomb with other efficient solutions on the market, such as diaphragm pneumatic pumps, it presents the largest investment course. This is because, in addition to being a more expensive bomb, it also needs specific parts to work, which results in a higher investment course.
It is not the best solution for abrasive fluids
Unlike the diaphragm pneumatic pump, rotary lobe pumps have a very intricate and sensitive design, which may favor the incidence of damage to the system and its parts during the abrasive fluid pumping.
Cannot work dry for a long time
Dry operation can cause destruction to components, engines and pump structure. This is because its internal components depend on the pumped fluid to remain lubricated.
Why choose a pneumatic diaphragm pump?
Diaphragm pneumatic pumps deliver a more efficient, cheap and easy -to -maintain solution to industries, delivering more efficiency and flexibility regardless of the fluid being pumped. Their biggest advantages are:
It is a pump that has excellent suction capacity;
Its without sealing design eliminates leaks and failures during operation;
Can deliver a soft and efficient flow with accurate measurements;
Pressure stop function, which prevents pump damage in case of obstruction or valve closure;
It works dry without causing any damage to your system, ensuring low maintenance cost
