The tubing behind the rollers recovers its shape, creates a vacuum, and draws fluid in behind it. This is specific to the ID of the tubing and the geometry of the rotor.
Flow rate is determined by multiplying speed by the size of the pillow.
This pillow stays fairly constant except with very viscous fluids. Go to Top Flow Rates 1. Go to Top 2. Go to Top 3. Go to Top 4.
