Our Optos and HP series pumps are reciprocating piston style, which means the pump fluid chamber is completely static. Therefore, at a constant stroke, the same amount of fluid is delivered to each pump—this means reproducibility is very high by design.

Our Optos Series pump is a single piston pump, so there is some pressure fluctuation as the pump transitions from the pump part of the piston stroke to the refill part of the piston stroke. This can be controlled with a pulsation damper/pressure transducer.
