DP-2000 Sample Pump
DP-2000 Sample Pump, refer to Appen-
dix A, page 25 , is a positive displacement
plunger pump. It’s robust design provides
for dependable sampling service, while also
providing a simple to maintain pump, with
few internal components. The pump has an
adjustable displacement of .1 to .4 cc per
stroke. The set displacement may be viewed
at the volume adjustment knob, refer to Ap-
pendix A, page 26 , located on the top of the
DP-2000 pump. Adjustment is simple. Turn
the volume adjustment knob clockwise to
increase the pump volume displacement per
stroke, or turn the volume adjustment knob
counter clockwise to decrease the pump
volume displacement per stroke. Final con-
trol of the volume of sample to be gathered
during the sample cycle period, is achieved
by the controller.
This pump has internal pressure balancing
capabilities that allows the pump to func-
tion properly when the pipeline pressure is
greater than the sample vessel pressure, or
when the sample vessel pressure is greater
than the pipeline pressure.
Each time the pump strokes, product pre-
viously captured in the pump chamber is
forced towards the sample cylinder. As the
pump plunger returns to a resting state a
new fresh sample is captured in the pump.
Once the pump completes its stroke, the
cycle is ready to begin again.
Filter Regulator
The DynaPak Filter Regulator, refer to Ap-
pendix A, page 29 , is a stainless steel filtered
regulator to supply the supply gas required
to actuate the sample pump. It is capable of
providing actuation pressure from pipeline
pressures to required actuation pressures in
a single dependable step.
Maintenance is minimal, but is certainly de-
pendant on gas quality. Should the gas sup-
plied to the filter regulator require significant
filtration, replacement of the filter may be
more frequent than normal, refer to System
Maintenance, page 16 .
