2.2.5 Draining Overflow
The drip tray outlet on the pump cylinder provides a means of
draining fluid from seal leakage. Use a section of 1/4” ID flexible
tubing to divert the leakage away from the pump.
To install the drain tube, push one end of the tubing over the end of
the drip tray outlet, as shown in Figure 2-3.
NOTE
The 1000x has two drain tube outlets, one for the drip tray, and one
for the splash pan, located at the bottom of the pump (refer to Figure
2-4). The 1000x also includes a wash gland as a standard feature
(refer to Section 2.2.6 "Cylinder Washing - Wash Gland" for details).
The wash gland tubes can also be used as lines for draining away
fluid.

2.2.6 Cylinder Washing -
Wash Gland
A thin film of liquid wets the inside of the cylinder each time the
piston travels up the cylinder. The lowest flow rates are conducive to
the most abrasive or corrosive pumping environments, as the
deposited film remains on the inside of the cylinder wall for the
longest time.
The SyriXus 1000x syringe pump is equipped for cylinder washing,
with two 1/8” tubes on the back to feed and drain the wash gland, as
shown in Figure 2-4.
A small pump can be used to deliver the wash fluid through one of the
two tubes to rinse the cylinder and seals. The second tube drains the
wash fluid to waste. If the system is configured to recirculate the wash
fluid, ensure that you change the wash fluid at regular intervals.
Select a wash fluid that will best flush the cylinder of any residue left
by the pumped fluid, yet will not damage the seals.
Caution
The pressure in the wash gland and line should NEVER exceed the
system pressure or the wash pressure limit as labeled on the pump.
Units with a wash pressure limit label can be damaged if the pres-
sure is exceeded.
