Pressure Washer Pump used to pressurize pressure vessel?

Click For Summary
SUMMARY

To pressurize water in a small pressure vessel up to 1500 psi, using a pressure washer pump is a viable option. The Simoniz 2000 PSI Electric Pressure Washer and the 3.5 GPM @ 2,000 PSI Pump Assembly are both considered for this application. However, the effectiveness of these pumps in maintaining a constant pressure for 5 to 10 minutes is uncertain. An alternative solution suggested is utilizing a gas (nitrogen) cylinder with a pressure regulator for short-term pressure needs.

PREREQUISITES
  • Understanding of pressure vessel design and safety standards
  • Familiarity with pressure washer pump specifications and capabilities
  • Knowledge of pressure regulation using gas cylinders
  • Basic principles of fluid dynamics and pressure measurement
NEXT STEPS
  • Research the specifications and performance of the Simoniz 2000 PSI Electric Pressure Washer
  • Investigate the 3.5 GPM @ 2,000 PSI Pump Assembly for suitability in pressurizing water
  • Learn about pressure vessel safety regulations and best practices
  • Explore the use of nitrogen cylinders and pressure regulators for pressurization applications
USEFUL FOR

Engineers, DIY enthusiasts, and anyone involved in projects requiring pressurization of fluids, particularly in small pressure vessels.

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)
