Is it allowed to install a filter at the outlet of a centrifugal pump?
Thread Content
For the filtration medium, our company has installed bag filters at the outlet of the centrifugal pump. Is it permitted from a regulatory perspective?
It’s completely fine, but you need to take into account the current of the motor, just make sure it doesn’t overheat.
Sure, but you also need to take into account factors such as the pressure on subsequent processing steps and other related process parameters. Is the medium particularly dirty? Even the inlet filter can’t handle it – what kind of medium does this centrifugal pump handle? It's also necessary to check the interior of the pump regularly.
The medium is gasoline. Some people say that this will generate a large amount of static electricity, so installation is not allowed.
Install anti-static devices, such as using wires for continuous connection, etc. Pay attention to the pressure at the back of the filter.
Filters are usually installed at the entrance; to prevent static electricity, these filters can be grounded. Current designs are rather conservative, and if a filter is used, an electrostatic grounding system will be provided.
Still having trouble with the inlet filter? Hazardous media have requirements regarding flow rate.
In the design of many oil depot product filling islands, filters are installed at both the inlet and outlet of the oil pumps, but it is necessary to consider whether the mesh size is appropriate to avoid pressure buildup.
