What pump should be used for solid-containing conditions? ? ?
Thread Content
We used two centrifugal pumps on site to pump the catalyst-containing medium, and blockages often occurred in the pumps and pipelines. As soon as a blockage appeared, the pump would lose suction, requiring us to clean the pipelines and disassemble the pumps to clean their interiors. Does anyone have any suggestions regarding alternative types of pumps that could be used instead? The current pump is used to handle coal tar with a solid content of around 100 degrees, at a pressure of 0.8 MPa and a flow rate of 12 m3/h. Can pumps such as screw pumps be used as alternatives? ? ? ?
Could you introduce the disadvantages of gear pumps?
Solid particle hardness, particle diameter,
Catalysts with a size of less than 10 microns, using coal tar as the medium; however, the viscosity of this medium changes significantly as the temperature drops, which makes it easy for pumps and pipelines to get clogged, and centrifugal pumps tend to empty out easily
Can we add each other on WeChat or QQ? I’d like to ask you something
Screw pumps are a good choice; your operating conditions are quite complex, with viscosity, particles, and temperature involved, so domestic pumps are likely not suitable for use. If a centrifugal pump is chosen, high requirements are placed on the pump itself; viscosity is a key factor, and selecting the right type of seal is not easy
