Is it necessary to install a filter on the pump inlet pipe? Under what circumstances does a filter need to be installed on the inlet pipe of the pump?

All must be installed to prevent debris from entering the inside of the pump body and damaging the impeller and pump casing.
Not all pumps are installed, it depends on the situation. Generally, a filter must be installed at the inlet of a canned pump or magnetic pump to prevent particulate impurities from being sucked in and damaging the pump. Usually the filter is divided into a process filter and a basket filter (depending on the situation). Whether there is a filter at the inlet of the centrifugal pump can be determined according to the process conditions. Of course, it is best to have one. Axial flow pumps and submersible pumps usually have no filter at the inlet. If the conveyed medium contains product crystals (required for the process), no filter should be installed before the pump.
It is not necessary to install a coarse filter, as long as the contaminant particles in the oil meet the oil cleanliness requirements of the oil pump. Sometimes a temporary filter is installed at the beginning of the operation and can be removed after a period of operation.

Generally, filters must be installed in front of screw pumps and gear pumps. Impurities have a greater impact on the pump. Centrifugal pumps are related to the process. If the process does not change frequently, the filter can be removed after running for a period of time.
It is a common practice to install filters on pipelines. In order to protect the pump and flow meter equipment, filters are generally located at the pump inlet and flow meter inlet.
It needs to be installed because no one can guarantee that the transported materials are clean, because long-term impact of tiny particles can make the pump impeller riddled with holes. Installing a filter extends the life of your pump.
For ordinary centrifugal pumps, pump inlet pipe filters are generally not installed under normal circumstances. You can consider installing a temporary T-shaped filter on the new device. Although the new device has been purged and filtered, it is generally difficult to clean it in a short time. In particular, some welding slag falls off slowly, and it takes a long time for the device to run to completely eliminate the welding slag. Therefore, it is best to install a pipeline filter for the new device. After the device has been running normally for several months, the filter element of the T-shaped filter can be removed to reduce the resistance drop at the pump inlet. For pump types such as canned pumps and magnetic pumps that have high requirements for impurities, pipeline filters should be installed to avoid damage to the pump.
I believe that any pump using a mechanical seal should have a filter installed at the inlet to protect the mechanical seal. Instead of protecting the impeller or pump casing
