What to do if the pressure of the pump and the pressure of the filter are not satisfactory?
Thread Content
There is a filter behind the pump; sometimes the pressure of the pump and that of the filter are too low, yet the material can still be pumped out. Why is that? The pressure in the pump is often high while the pressure in the filter is low, which prevents the material from being pumped out. What should I do? I appreciate your guidance.
Both the pump and the filter have low pressures, but material can still be discharged, which indicates that the filter is not clogged. However, the inlet to the pump is not receiving sufficient feed; in other words, the pump does not get enough material to operate properly, and this is harmful to the pump as well as the mechanical seal. This issue needs to be resolved promptly； If the pump pressure is high while the filter pressure is low, it must be that the filter is clogged; it needs to be taken apart for cleaning or a replacement filter should be used.
Reply to 2# Junior Clerk, thank you
"The statement that \"the pump pressure is often high while the filter pressure is low\" is rather vague. If the pressure at the filter outlet is low, it indicates a large pressure difference between the inlet and outlet of the filter, suggesting a high likelihood of clogging. Sometimes, both the pump pressure and the filter pressure are low, yet the material can still be pumped out; this implies that the amount of material is small when the pressure is low, allowing it to be pumped out. If the pump pressure is often high and the filter pressure is low, resulting in an inability to pump out the material, it indicates a problem with the selection of the filter – either its capacity is insufficient or the cross-sectional area of the flow channel is too small
There is a filter behind the pump; sometimes the pressure of the pump and that of the filter are too low, yet the material can still be pumped out. It is possible to check whether the pump inlet is blocked, and to ensure that the static pressure of the pump is not too low. The pressure in the pump is often high while the pressure in the filter is low, which prevents the material from being pumped out. This is mostly due to a clogged outlet filter.
