Over time, centrifugal pumps can develop various problems. In order for this not to happen prematurely, it is essential to perform regular maintenance on the centrifugal pump. In today’s post, we will introduce you to the most common problems that can arise when using centrifugal pumps and some of the possible causes.<\/p>\n
<\/strong><\/p>\n If it is pumping little or no liquid<\/strong>, the pump may not be fully submerged or properly aligned<\/strong>.<\/p>\n It may also be that the pump is leaking,<\/strong> and therefore the mechanical seal needs to be replaced.<\/strong><\/p>\n Another cause may be that air has entered the system<\/strong>, either in the suction pipe, in the air inlet or in the seal.<\/strong><\/p>\n Noise from a centrifugal pump is often due to cavitation.<\/strong> This occurs when there is insufficient pressure and some of the liquid<\/strong> is transformed into vapor. The vapor within the pumped liquid reduces the capacity of the pump. This phenomenon can damage the walls of the pump<\/strong> and reduce its service life.<\/p>\n Cast iron pumps can perform well for everyday applications, but can produce corrosion if exposed to low pH liquids<\/strong>. Cast iron resists neutral and alkaline (high pH) liquids well.<\/p>\n The best way to avoid corrosion in your pump is to choose a pump that is compatible with the fluid it has to pump.<\/strong> For example, stainless steel pumps are anti-corrosion.<\/p>\n One of the signs of bearing damage is sound or vibration between components<\/strong>.

Not pumping any or a small amount of liquid<\/h3>\r\nIf it is pumping little or no liquid<\/strong>, the pump may not be fully submerged or properly aligned<\/strong>.\r\n\r\nIt may also be that the pump is leaking,<\/strong> and therefore the mechanical seal needs to be replaced.<\/strong>\r\n\r\nAnother cause may be that air has entered the system<\/strong>, either in the suction pipe, in the air inlet or in the seal.<\/strong>\r\n
Cavitation<\/h3>\r\nNoise from a centrifugal pump is often due to cavitation.<\/strong> This occurs when there is insufficient pressure and some of the liquid<\/strong> is transformed into vapor. The vapor within the pumped liquid reduces the capacity of the pump. This phenomenon can damage the walls of the pump<\/strong> and reduce its service life.\r\n
Corrosion<\/h3>\r\nCast iron pumps can perform well for everyday applications, but can produce corrosion if exposed to low pH liquids<\/strong>.
