Pump selection
Thread Content
Hello everyone. I am looking to choose a feed pump for a plate and frame filter press, with a flow rate of around 8–10 m3. I initially thought of using a screw pump, but since our material is slightly acidic, with a pH of around 5, a screw pump might not be the best choice. I was wondering if there are any other types of pumps available that can handle a head of around 60 meters
Temperature? Particulate matter content? Usage cycle?
A corrosion-resistant and wear-resistant slurry pump can be selected; the material is ultra-high molecular weight polymer, equipped with a double-end mechanical seal (with flushing). For contact details, see the signature.
For filter presses, UHB series mortar pumps are required; you can contact me as I have many relevant cases to share.
Magnetic pump: It uses a plastic impeller and is highly resistant to acids and alkalis; the medium used must be clean, free of particles, otherwise its service life will be very short. Screw pump: A single-screw pump can be chosen, allowing both the screw and the screw sleeve to be made of acid-resistant materials
The pH value is merely a measure of acidity or alkalinity, and it has no direct relation to corrosivity. It is recommended to select the appropriate type first based on performance parameters, and then choose the material according to the corrosivity of the actual medium
The pump used in filter presses handles large-volume feed at the initial feeding stage, as well as prolonged high-pressure holding at the later stages of compression
Firstly, for the single-screw pumps NM063-2S or BN17-12, a rotor made of corrosion-resistant material can be used
