4 Introduction
Pump Configuration
The DP-3000 Series Pumps have three key configurable components that determine performance. When
you receive the pump for your system, it should be configured as requested for your application. The key
components and how they affect pump performance are described in the table below. For more detailed
information, see the Operation section.
Table 1-1 Key Configuration Components
Key Component Performance
Stopcock
Controls the flow direction of material for dispensing and refilling. The
nylon stopcock is used for fluids containing alcohol, acetone, or other
solvents not compatible with polycarbonate. The polycarbonate stopcock
(shipped with the pump) is used for all other fluids.
Pumping Chamber
Size
Determines the maximum shot size per refill. Affects the material
flow rate.
Pump Motor Affects the material flow rate range.
The naming scheme used for determining the model number for the DP-3000 Series pumps reflects the
specific configuration as described below. You can use this information to make sure you have received
the correct configuration.
Table 1-2 Model Number and Configuration
DP-3XYZ X (stopcock) Y (chamber size) Z (motor ratio)
1
Polycarbonate
(Yellow/Clear)
N/A Very low flow rate
2 N/A Small, 1 cc capacity between refills Low flow rate
3
Nylon
(White)
N/A N/A
4 N/A Large, 2 cc capacity between refills Medium flow rate
0 N/A N/A
Encoded motor
(all flow rates)
For example, a DP-3120 is a configuration with a disposable, polycarbonate stopcock, a 1-cc piston, and
an encoded motor.
Multiple spare pumping chambers are included with all DP-3X2Z and DP-3X4Z model pumps. If one
pumping chamber becomes clogged during a production run, the spare chamber can be installed to avoid
stopping the run in order to clean the pump.
For convenience, motor body types and stopcock materials are color coded for easy identification.
Spur Gears
The DP-3000 has one more configurable component not reflected in the naming scheme. The Spur
Gears, which also affect the flow rate, can be changed and configured to achieve various flow rates. Spur
Gears are available in the DP-3000 Upgrade Kit. See “Upgrade Kits” later in this section.
