Maximum Working Pressure of Accessories
To reduce the risk of serious injury including fluid
injection and splashing in the eyes or on the skin
which may be caused if component ruptures, all
accessories added to the reciprocator power supply
side must have at least 600 psi (4.1 MPa, 41 bar)
maximum working pressure.
All accessories added to the pump fluid outlet side
must have at least 7500 psi (51 MPa, 517 bar)
maximum working pressure.
