2. Peristaltic pump - Wikipedia

   en.wikipedia.org/wiki/Peristaltic_pump

   The ideal peristaltic pump should have an infinite diameter of the pump head and the largest possible diameter of the rollers. Such an ideal peristaltic pump would offer the longest possible tubing lifetime and provide a constant and pulsation-free flow rate. Such an ideal peristaltic pump cannot be constructed in reality.

3. Cole-Parmer - Wikipedia

   en.wikipedia.org/wiki/Cole-Parmer

   The company was founded by Jerry Cole and John Parmer in 1955 and took up shop in a 1,200-square-foot (110 m 2) loft on West Illinois Street in downtown Chicago. [2] In the 1960s, Cole-Parmer acquired Masterflex peristaltic pumps, followed shortly by the purchases of Gilmont Instruments and Manostat Pumps.

4. Net positive suction head - Wikipedia

   If an NPSH A is say 10 bar then the pump you are using will deliver exactly 10 bar more over the entire operational curve of a pump than its listed operational curve. Example: A pump with a max. pressure head of 8 bar (80 metres) will actually run at 18 bar if the NPSH A is 10 bar. i.e.: 8 bar (pump curve) plus 10 bar NPSH A = 18 bar.

5. Postperfusion syndrome - Wikipedia

   Furthermore, the Van Dijk study showed no difference between the on-pump and off-pump groups in quality of life, stroke rate, or all-cause mortality at 3 and 12 months. A study by Jenson et al. published in Circulation found no significant difference in the incidence of cognitive dysfunction 3 months after either OPCAB or conventional on-pump ...

6. Metering pump - Wikipedia

   en.wikipedia.org/wiki/Metering_pump

   Metering pumps are not good at pumping gases. Sometimes, a metering or similar pump has to be primed before operation, i. e. the pump head filled with the liquid to be pumped. When gas bubbles enter a pump head, the compression motion compresses the gas but has a hard time forcing it out of the pump head.

7. Peristalsis - Wikipedia

   en.wikipedia.org/wiki/Peristalsis

   A peristaltic pump is a positive-displacement pump in which a motor pinches advancing portions of a flexible tube to propel a fluid within the tube. The pump isolates the fluid from the machinery, which is important if the fluid is abrasive or must remain sterile.
