- The traveling cylinder (Travcyl™)
design is internally-sealed by sliding ceramic plates, so no
external valves are needed.
- Each piston/cylinder assembly slides from the inlet where
it fills (aspirates), to the outlet where it discharges.
- Each piston is at a different point in the aspirate/dispense
cycle at any given time.
- Flow pulsation is reduced compared to single-piston pumps
because there are almost always two cylinders dispensing.
