Pressure relief valve adjustment
1.
Start by screwing completely the back pressure adjustment screw (
10'
).
2.
Start the pump and wait until fluid passes through the pressure relief valve into the
evacuation port. (use the bleed valve to prime the pump if necessary)
3.
Use the adjustment screw (
10
) to obtain the desired pressure set point.
4.
Once the desired set-pressure is obtained, tighten the counter nut (
11
). See note.
5.
Stop the pump and slowly open the bleed valve to release the system pressure.
Proceed with the back pressure valve adjustment.
Back pressure valve adjustment
1.
Start the pump and wait until pressure is build up.
2.
Use the adjustment screw (
10'
) to obtain the desired pressure set point by initially
unscrewing the back pressure adjustment screw (
10'
).
3.
Once the desired set-pressure is obtained, tighten the counter nut (
11'
). See note.
Important: It is recommended to set the back pressure at 20psi to 30 psi over the process
pressure.
Notes:
The maximum torque to be applied on the adjustment screws (
10
&
10'
) and counter
nut (
11
&
11'
) is
25 in-lb
.
