  • The highest flow rate and the highest pressure generation of any L/S® pump head
  • Offers better suction lift, viscous fluid transfer, and long tubing life—pump at pressures up to 150 psi using L/S high-pressure pump tubing.
  • Pump head design allows tubing to enter and exit the same side of the pump head—mount the pump head to best suit your space and application needs.
  • Rollers, bearings, rotor plates, and rotor shaft are made of stainless steel (SS); occlusion bed is made from polyphenylene sulfide (PPS). SS and PPS have excellent chemical resistance; SS also offers high durability and long service life.
  • Compatible with all L/S drives that accept two or more pump heads. Consult drive specifications; the L/S High-Performance pump head is not stackable.
  • Accepts high-performance precision tubing sizes L/S® 15, L/S® 24, L/S® 35, and L/S® 36
  • Also accepts L/S high-pressure tubing sizes L/S® 14HP, L/S® 16HP, L/S® 15HP, L/S® 24HP

Does Cole Parmer sell replacement screws for the front? Mine got bent, and I need to replace just the piece.
Answer
The replacement screw is part number 00014XO.Answered on 1/24/2011 by Jen from Technical Support
Is there a replacement rotor for the pump head and does it come with the bearings?
Answer
The rotor assembly can be ordered under 77250-69. Included are: 1 shaft, 2 rotor plates, 3 rollers, 1 sleeve, 2 bearings, 1 washer, 1 retainer ringAnswered on 9/13/2013 by Polo from Technical Support
Is there a version of this head for use with thin walled tubing? (sizes 13,14,16,25,17,18)Thanks
Answer
This head and type of head are specifically for thicker wall higher pressure applications with the 13, 14, 16, 25, 17, and 18 sizes are not made for. We have standard and Easy-Load style heads for the "regular" tubing sizes. For an example, but not a definitive list, please see part number 77800-50 and contact us by phone or email if you have any other questions.Answered on 12/9/2010 by Jen from Technical Support
Is this compatable with 7520-60 masterflex console drive?
Answer
Yes, this L/S head is compatible with the L/S drive you listed.Answered on 8/10/2011 by Jen from Technical Support
Is this head compatible with a 07571-00 E/S portable sampler?
Answer
Unfortunately this pump head (77250-62) is not compatible with this sampler. We suggest using a 07518-12 Easy-Load pump head which can be used with high-performance tubing like sizes L/S 15 and L/S 24. For additional help, please contact our Application Specialists at the number found under the Contact Us section on our website.Answered on 7/14/2010 by Jaime from Technical Support
So this pump head will pump into a line at up to 150 psi?
Answer
This pump is able to handle the pressure of 150 psi with he L/S 14 High Pressure PharMed BPT tubing, catalog number 95664-14. Other tubing sizes and formulations will be able to handle less pressure.Answered on 5/3/2013 by Mike S from Technical Support
What is the part number for L/S 24 tube that can be used with this pump head?
Answer
The are various L/S 24 tubing compositions that are compatible with this head. The composition of the tubing you choose will depend upon the fluid you are pumping and any other specifications you may need to meet. Please contact our technical application specialists for additional assistance (contact information can be found in the "contact us" section on the web page).Answered on 8/26/2010 by Jen from Technical Support
Which pump head has longer tubing life time 77250-62 or 77201-62
Answer
Both pump heads you have reference will use the high performance pump tubing. Tubing life will be dictated by the formulation of tubing that is used, the RPM setting off the drive being used and the specifics of the application, not the pump head.Answered on 9/9/2013 by Jose from Technical Support
