Plate and frame filter
Thread Content
Which pump is better for plate and frame subfilter? ? ? ?
Different materials are filtered, and different pumps are selected.
Normally, the pump selection is based on the production capacity of the filter press and the pressure required for filtration of the material itself, to determine the required pump flow and lift, and then based on the material characteristics, whether there is corrosion, and the temperature, the material of the pump is determined. High-temperature corrosive materials require some effort in selecting a pump. For other materials, you can consult several companies based on the manufacturer's recommendations and there will be no problem.
We use a plate and frame filter to filter the raw liquid viscose of viscose fiber, using gear pumps and screw pumps.； In individual workshops, I have seen centrifugal pumps used to filter sludge in zinc sulfate solutions. The filter material should be very loose.
