*Dyna-Star HP Pump Models are rated for 5000 psi (34.47 MPa, 344 bar) maximum working pressure, however,
when a vent valve is installed on the HP Pump, the maximum working pressure must be reduced to 3500 psi (24.1
MPa, 241 bar).
**Flow capability depends on viscosity, type of fluid, temperature, etc.
