D Series Syringe Pumps: Model 1000D
Section 2C 1000D Liquid System Connection & Accessories
2C.2.4 Drain Tube The overflow outlet on the pump cylinder provides a means of
draining fluid from seal leakage. Use two pieces of 1 4" ID flexible
tubing to divert the leakage away from the pump. To install the
drain tubes, attach one end of each piece of tubing over the ends
of the drip tray outlet and the splash pan outlet, shown in Figure
2C-2. You may also drain the fluid away from the pump by connecting
to the two 1 8" tubes protruding from the back of the
pump.
Note
The drain tubes shown in Figure 2C-2 may appear slightly different
than that on your pump.

2C.3 Cylinder Washing and
Purging
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 1000D pump is equipped for cylinder washing. The two 1 8"
tubes located on the back of the pump feed the wash gland.
