What type of pump would work well for this application?

Need pump recommendation for a stand alone shower/water flosser using the following:

The pump needs to be able to put out 100+psi for the water flosser. How can the pump be rated for this type of pressure? Most pumps do not have pressure rating but head, flow rate, power in watts etc but not specifically pressure. Not sure how the orifice of the flosser determines the pressure and how the power rating or head of the pump can be translated into pressure or velocity of the fluid coming out of the nozzle of the flosser or the shower. The threads of the pump and the shower/flosser should match for ease of putting things together. A link to the suction tube with filter if anyone knows would be helpful. A few pumps that are being considered:

A drawing of how the system would look like:

Thank you.

100 PSI for such a small amount of water is not practical. It would be too much pressure for the shower wand anyway. Just get a regular Waterflosser from Waterpik, that has it own pump and motor. The water for the shower wand and to fill the waterpik container could be supplied by a small 12V RV style pump if you wanted. A good jet pump with a pressure tank and pressure switch would be best as it would be longer lasting and supply much more water than an RV pump.
