Regarding oil pumps in underground oil tanks
Thread Content
Which is better, a self-priming pump or an submersible oil pump, for transferring the oily waste from underground oil tanks outside that area?

Advantages of submersible pumps: high efficiency ； Disadvantages: Difficult to repair, complex mechanism. Individuals tend to prefer self-priming pumps.
Suction pumps are safer; the original poster can search online for incidents related to safety problems with submersible pumps.
It is better to choose a gear pump with self-priming capability.
Check operating conditions； At high temperatures (near the vaporization pressure) and at large submersion depths (over 7m), it is recommended to use a submersible pump. Submersible pumps can remain operational, but maintenance is inconvenient, as wear-resistant and vulnerable components such as bushings often break down. The temperature is not high and the submersion depth is low; a self-priming pump is recommended ； Self-priming pumps have low leakage, are easy to maintain, and offer good safety performance ；
Consider the specific gravity and viscosity of the dirty oil when selecting a pump. Self-priming pumps have a limited self-priming height; it is necessary to take into account the height of the dirty oil tank as well. They are convenient for maintenance and repair. Submersible pumps, on the other hand, have high maintenance costs, and any problems that arise can be serious issues
