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 AIR TO CYLINDER switch is off.
3. Make sure the CYLINDER switch is set to FILL.
4. The Consistometer has a rupture disk to prevent damage due to over
pressurization. If the pressure inside the cell exceeds 28,000 PSI for
the Model 2025 Consistometer or 45,000 – 50,000 PSI for the Model
2040 Consistometer, the disk will rupture and release the pressure. If
this happens, the cell cannot be pressurized until the rupture disk has
been replaced.

Rupture Disk
The rupture disk is located inside a square block just upstream from
the lter 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.
