Masterflex Item # WW-77200-32
Automatic retention holds tubing securely in place with no manual adjustment—just load the tubing and start the pump
  • Four-roller rotor improves pressure performance and mechanical stability while reducing pulsation.
  • Improved occlusion bed geometry lengthens tubing life.
  • Polyphenylene sulfide (PPS) housing with either stainless steel (SS) or cold-rolled steel (CRS) rotor—choose CRS for economy or SS for greater durability and chemical resistance.
  • Model 77201-62 with adjustable occlusion gives you the option of loosening occlusion for longer tubing life or increasing occlusion for higher pressure.
  • Each pump head for high-performance precision pump tubing accepts tubing sizes L/S® 15, L/S® 24, L/S® 35, and L/S® 36. Achieve flow rates of 1.7 to 2900 mL/min (1 to 600 rpm).

More About this Item

These pump heads accept the four high-performance precision tubing sizes. High-performance precision tubing has a thicker wall than precision tubing enabling better pressure generation, greater suction lift, and greater ability to pump viscous fluids.

This pump head requires an L/S drive equipped with open-head sensor functionality or the use of the 77097-00 open-head sensor retrofit controller.
