Pressure Washer Pump used to pressurize pressure vessel?

AI Thread Summary
A user is seeking advice on using a pressure washer pump to pressurize water in a small pressure vessel up to 1500 psi for 5 to 10 minutes. They provided links to two specific pressure washer models for consideration. One response suggested using a gas cylinder with a pressure regulator instead, but the user clarified that they require pressurized water without trapped air. The discussion centers on the feasibility of pressure washer pumps for this specific application. The conversation highlights the need for a suitable solution to maintain the desired pressure effectively.

Hi, I am working on a project that requires me to pressurize water in a small pressure vessel up to a pressure of 1500 psi. I am searching for a pump to do this. Do you guys think a pressure washer pump such as this one:
http://www.canadiantire.ca/AST/browse/4/Auto/CarWashingCleaning/PressureWashersElectric/PRD~0398557P/Simoniz+2000+PSI+Electric+Pressure+Washer.jsp?locale=en

or this one:
http://www.princessauto.com/pal/product/8149650/Pumps-%26-Unloaders/3.5-GPM-@-2,000-PSI-Pump-Assembly

will be able to accomplish the task and hold pressure constant at 1500 psi for 5 or 10 minutes?

Thoughts anyone?

Thanks,
Josh

If you only need to ho;d pressure for a short time and don't have to repeat the operation too often have you thought about a gas (nitrogen) cylinder and a pressure regulator?
 
Hi thanks for your response. It has to be pressurized water in the tank (ideally with no air trapped inside)

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
