2B.4.2 Cooling/Heating Jacket An optional cylinder temperature jacket (P/N 68-1247-057) is
available for use in maintaining cylinder temperatures (30 to
100°C) by circulating liquids, such as water or water/ethylene
glycol solution, through the hose connectors.
See section 2A.4.2 for installation instructions.
2B.5 Nitrogen Purge A thin film of liquid will wet the inside of the cylinder each time
the piston travels up the cylinder. Corrosive liquids drying in the
air can cause the cylinder to corrode. This corrosion occurs at
varying rates, based on the liquids and pumping conditions being
employed. The lowest flow rate engenders the most corrosive
pumping environment, as the deposited film has the longest time
to corrode the inside of the cylinder wall.
The 500D pump is equipped with a purge connector (Figure
2B-6). The purge connector enables the pump cylinder beneath
the piston to be purged with nitrogen, which inhibits cylinder
corrosion and may increase the useful cylinder life. Figure 2B-6
shows a typical purge connection to the purge tube on the back of
the pump.
To install the nitrogen purge
1. Attach gas supply by slipping the plastic tube over the
purge connector, see Figure 2B-6.
