Section 2 Fluid System Connections and Accessories
• Cylinder cap seal - The cylinder cap seal maintains the pressure
within the cylinder.
• Piston seal - The piston seal maintains the pressure within the
cylinder.
• Wiper seal - The wiper seal cleans the inside of the cylinder. In
the model 1000x pump, the wiper seal faces the same direction
as the piston seal to prevent leakage of the wash gland fluid. All
other models have the bottom seal facing down as shown in
Figure 2-11.
• Wear ring - The wear ring supports the seal against movement
within the cylinder and keeps the piston centered in the cylinder
bore.
SyriXus series syringe pumps are available in two metal variants. The
1000x, 500x, 500xv, 260x and 65x use Nitronic
cylinder. The 260x and 500x are also available with Hastelloy
inders. The wetted materials variants are factory installed, conversion
from one variant to the other is not supported.
