The accuracy of a peristaltic pump depends on several factors:

• Tubing quality and elasticity: Tubing must maintain consistent dimensions and resilience.
• Number of rollers: More rollers = smoother, less pulsating flow.
• Motor precision: Stepper and servo motors ensure repeatable RPM control.
• Calibration and control system: Electronic feedback and calibration improve reproducibility.
• Operating mode: Volume or programmable modes give higher accuracy than manual control.
In well-designed systems, accuracy can reach ±0.5–2%, depending on application and tubing size.
