About submersible pumps

Dear experts, may I ask what is the typical outlet pressure of submersible pumps? And why can’t submersible pumps be used in liquid oxygen?
It’s best to consider specific manufacturers, as there are differences among them. For liquid oxygen, it’s most likely related to the pump material and some special designs
The head of submersible pumps ranges from several dozen meters to 2,000 meters, while the discharge pressure of LNG high-pressure transfer pumps can reach 8 MPa
It cannot be used with liquid oxygen because the motor is not explosion-proof
The head of a submersible pump is determined by the number of stages. For safety reasons, liquid oxygen pumps come in horizontal and vertical versions; I have never seen any submersible versions of them.
The outlet pressure is the sum of the inlet fluid pressure and the pump head; the head depends on factors such as the number of pump stages, rotational speed, and impeller diameter. Generally, the pressure difference between the inlet and outlet of a two-stage submersible pump is around 6 kilograms. Professional repair for submersible pumps: 17816608845
