SediGraph III 5120 Service Fluid module
Mar 2010 2-9
The air valve (PN 512/34012/00) is located on the left hand side of the rear of the fluid
module. This valve is unique and cannot be used in another valve position. This valve is used
during a rinse operation, or to help rid the cell of bubbles during a fill operation, or whenever
the instrument determines there are bubbles in the sample.
Fluid pumps
There are two pumps used in the 5120, both are located at the front of the fluid module. Both
pumps have EZ Load pump heads (PN 512/62800/00) and pump motors (PN 511/25889/00).
Both pump head assemblies are attached to mounts which have vibration dampening
grommets (to help cut down on vibration and noise).
Cell pump
This pump (PN 512/62800/00) controls flow (speed and direction) through the cell assembly.
This pump is also used when 100% (full scale) runs are made before a sample is run. Loading,
emptying and rinsing of the cell assembly all are accomplished using the cell pump. The flow
rates of the cell pump are below: The tolerance of all of these speeds is +
10%.
• Speed 1 – 75ml/min
• Speed 2 – 138ml/min
• Speed 3 – 224ml/min
• Speed 4 – 275ml/min
• Speed 5 – 324ml/min
The cell pump motor (PN 511/25889/00) is directly behind the cell pump head and is coupled
to the pump head by a small sleeve on the motor’s output shaft.
Mixer pump
The mixer pump (PN 512/62800/00) circulates the fluid left in the system after the cell has
been loaded and the cell pump shuts off. The flow rate of the mixer pump is below: The
tolerance of the speed is +
10%.
• 205ml/min
The mixer pump motor (PN 511/25889/00) is directly behind the mixer pump head and is
coupled to the pump head by a small sleeve on the motor’s output shaft.
