Seek corrosion-resistant pumps
Thread Content
I’m seeking advice from experts regarding the selection of a corrosion-resistant pump: the medium is a mixture of ammonium hydrogen fluoride and anhydrous hydrogen fluoride, with a temperature range of 120–160°C and a specific gravity of 1.4–1.6; it tends to crystallize. There must be no leaks during operation, with a flow rate of 0–2 m3/h and a head of 10–20 meters. Installation method: External installation, horizontal. Thank you so much!
Insulated magnetic pumps can be considered; they eliminate leaks and can also solve the crystallization problem.
It’s easy to find a pump manufacturer! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
Try a magnetic pump; it’s really hard to choose one for substances that tend to crystallize
Alloy pumps can also be considered; try tantalum or titanium pumps as well
Does the magnetic sleeve of a magnetic pump have a long lifespan at high temperatures? Higher temperatures cause faster demagnetization, right?
There are high-temperature resistant magnetic pumps; those that can handle temperatures up to 250°C work as well
High-temperature magnetic pumps with jackets (not ordinary magnetic pumps) can solve this issue, as the jacket is heated using steam.
The flow rate is too low; the magnetic pump is unable to address the cooling issue, so it cannot be used. It is recommended to use a high-temperature resistant pure PTFE diaphragm pump. BELLOW pump.
Thank you all for your suggestions; they are very helpful!
High-temperature resistant magnetically driven vortex pumps can also be considered. Pump head made of stainless steel. Additional electric heating or insulation measures
