Welcome to the NEW and IMPROVED Masterflex.com!
The Easy-Load pump head combines an over-center cam with automatic tubing retention in a rugged, chemical-resistant housing. This design allows fast, easy tubing changes without removing the pump head from the drive. Built-in tubing guide ensures correct positioning of tubing to maximize performance and pump tubing life. Spring-loaded tubing retainers ensure tubing is secured automatically to promote long tubing life and optimize performance of each tubing size.
Select from polysulfone (PSF) housing with CRS or SS rotor, or polyphenylene sulfide (PPS) housing with SS rotor. PSF is economical, while PPS offers enhanced chemical resistance. SS rotors feature PTFE-sealed bearings for long life and reduced maintenance; CRS rotors have Buna N shielded bearings.
Dual-channel hardware allows two pump heads to operate on a single drive—order hardware set 77601-96 separately.
With single or multiple channels, tubing can be changed in each channel without removing the EASY-LOAD pump heads from your drive.

Comments about Masterflex<reg> I/P<reg> Easy-Load<reg> pump head, PSF housing/SS rotor.:
i could just spend hours and hours and hours and hours and hours and hours and hours and hours watching that little silver thing spin around and around and around and around and around and around and around and around and... where was i? oh yeah, i wish it came in more colors. seriously, what do you expect me to say about a peristaltic pump head? it showed up when it was supposed to and it worked when i hooked it up. if it didn't you would have heard from me way before this.

Q:What is the maximum viscosity fluid this pump can handle?
A:This is a pump head only, and not a pump. This pump head accepts tubing sizes I/P 26, I/P 73, I/P 82. The size I/O 82 tubing can handle approximately 4000 cp, but the flow rate would only be about 75 mL/min. As the viscosity increases, the maximum flow rate significantly decreases.
Q:Is this pump head compatible with C-Flex 3/8" and 1/2" ID tubing?
A:The MasterFlex pump heads require the use of the MasterFlex specific tubing, such as the I/P 26, I/P 73, and I/P 82 tubing sizes. These tubings are manufactured to extremely tight tolerances on the wall thickness such that the distance between the rotor and the occlusion bed are an exact match to the compressed size of the tubing. Using a standard-sized tubing can lead to premature rotor, motor, and tubing wear; as well as poor performance.
Q:What pumps will work with this pump head. We have several MasterFlex L/S drives.
A:These heads are meant for use with I/P series drives. They are not compatible with L/S drives.
Q:Do you have 3D CAD model so can integrate it in to my design
A:There are no 3D CAD files available for these heads.
Q:can this pump use 1/16" I/D tubing?
A:This pump head is for the Masterflex I/P system, and the smallest size tubing that can be used in it is the I/P 26 tubing, which has an ID of approximately 1/4". If you need to use 1/16" ID tubing then you need to look at the Masterflex L/S systems. The L/S 14 tubing size has an ID of 1/16".
Q:Does this pump have a ATEX Head or a Non-ATEX Head?
A:For an ATEX approved version, please look at part number 77601-80.
Q:Does this pump head accept C-Flex 3/8" ID, 1/8" wall tubing?
A:Use of nominal tubing in this head will void the warranty. This accepts sizes I/P 26, I/P 73, and I/P 82. The C-Flex part numbers for these sizes is 06424-26, 06424-73, and 06424-82, respectfully.
Q:How much does the pump head weigh?
A:This head weighs about 4 pounds.
Q:Does the pump head have a safety interlock to stop the pump from running when housing is open?
A:Currently there is no stop mechanism when the pump lever is open. The pump must be manually turned off.
