Maintenance
Rupture Disk
If you hear the pump running but no pressure is building in the test cell:
1.
Make sure the “Pressure Release Valve” is completely closed.
2.
Make sure the "FILL/DRAIN CELL" switch is set to FILL.
3. The Consistometer has a rupture disk to prevent damage due to over
pressurization. If the pressure inside the cell exceeds 28,000 PSI,
the disk will rupture and release the pressure. If this happens, the cell
cannot be pressurized until the rupture disk has been replaced.
High-Pressure Filter
Rupture Disk
The rupture disk is located inside a square block just upstream from
the filter on the inlet side of the pump. To replace the rupture disk,
remove this block, discard the ruptured disk, and install a new disk.
Then re-install the block into the plumbing line.
