A Husky conta com diversos modelos de bombas pneumáticas de diafragma e de acionamento elétrico, conseguindo atender às diversas necessidades de indústrias de todos os segmentos. Mas como essa bomba consegue lidar com fluidos de alta viscosidade?
A viscosidade é uma questão muito relevante para as empresas, e é necessário escolher a bomba certa para as suas aplicações de forma garantir uma operação segura e eficiente. Por esse motivo, é muito importante determinar se a sua bomba consegue lidar com esse tipo de fluido antes de fazer a sua escolha.
The density of the fluid to be pumped is one of the most important factors to consider when choosing a pneumatic diaphragm pump. These pumps have control balls that rise and fall as the pressure inside the fluid chambers changes. These spheres, which can be made of elastomer or metal, behave according to the density of the fluid being pumped, and for this reason, viscosity is an essential factor to ensure the efficiency of this pump.
When the pump deals with low-viscosity fluids, the behavior of this sphere is not usually of critical importance, since the viscosity of this fluid is not restricted during the process of moving this structure.
However, when dealing with more viscous materials, it is necessary to have a sphere that has the greatest weight so that it can move through this type of fluid and settle in the expected way. When the ball present in the pump is too light it cannot enter the fluid and settle. Considering these factors, the more viscosity the fluid has, the heavier the ball present in your pump should be.
Your pump's piping system should also be considered when it comes to viscosity. It is important to ensure that the pump is able to extract the unexpected fluid with the suction line that is implemented.
In this regard, it is important to check the dry lift capacity of your pump and whether it exceeds the suction line loss. For this, it is possible to calculate the loss in parallel with the intended flow volume.
The fluid from your pump will only be able to be transferred if the inlet pressure is greater than the TDH of the system. To calculate this value it is necessary to determine the line friction loss and the total static head. When this value is not satisfactory, it may be necessary to ensure a larger diameter in the discharge line in order to reduce losses.
