2.2 DP/SP Interior Components
The pump’s mechanical components are located directly behind the front door of
the module. Figure 2-3
shows the mechanical components of a DP that contains
both a gradient pump (pump 1) and an isocratic pump (pump 2).
For servicing components, the component mounting panel slides out about 5 cm
(2 in) for easy access to components. To pull the panel out, use the handles on the
top and bottom of the panel.
