At a submersion depth of 2.8 meters (for buried tanks), is it possible to use a self-priming pump?
Thread Content
The submersion depth is 2.8 meters, and the flow rate is approximately 30–35 tons. The media involved include toluene, ethyl acetate, butane, ethanol, etc. If the owner requires leak-free performance, ordinary submersible pumps are not suitable. Is it possible to use a magnetic self-priming pump? Is a siphon tank needed?
At normal temperature and pressure, with a simpler inlet pipeline, a magnetic self-priming pump is sufficient.
The owner’s medium will produce bubbles! Can adding a siphon tank solve the problem of not being able to draw up liquid after bubbles form?
It’s better to use a centrifugal pump with a siphon tank; organic solvents present more complications.
Flammable medium; mechanical seals are not suitable
Explosion-proof motor, WB2 type mechanical seal
With a self-priming pump, a siphon tank is not required
Sure! Generally, self-priming pumps can achieve a suction lift of 5–6 meters.
