INTRODUCTION AND GENERAL DESCRIPTION
This EASY-LOAD Pump Head when combined
with a MASTERFLEX
®
I/P
®
drive or compatible sys-
tem is designed to provide a simple easy-to-use
peristaltic pump system. The Pump Head accepts
3 different tubing sizes for a wide range of flow
rates. The unique over-center cam design and
automatic tubing retention allows quick tubing
changes and greatly reduced maintenance time.
Each pump is supplied complete with a 20 in
(50-cm) length of tubing, one mounting hard-
ware package and this manual. A flat-bladed
screwdriver is required to complete installation.
DRIVE COMPATIBILITY AND SETUP
The I/P EASY-LOAD Pump Head is available in two
drive shaft lengths depending upon the drive
chosen. The short shaft versions have a standard
tang interface. Mount the pump head using the
5 screws provided. (See Figure #1.)
NOTE: Raise occlusion bed to expose mounting
holes for top 2 short screws.
TUBE LOADING
1. Be sure the pump drive is turned off.
2. Move the lever to the left to open the pump.
3. Load the correct tubing. (Figure #2.)
4. Move the lever to the right to close. (Fig. #3.)
WARNING: Stop the drive when changing the
tubing or its position in the rotor
mechanism (the rotor is partially exposed
when the LOADING LEVER is in the open
position).
NOTE: For optimum tubing life, keep tubing
straight when entering and exiting the pump.
OCCLUSION ADJUSTMENT
Adjust occlusion setting on top of pump head.
(Figure #4.)
“3” for nominal performance;
“4” or “5” for increased pressure/vacuum with
reduced tubing life;
“1” or “2” for longer life with less pressure
and vacuum.
NOTE: For optimum performance turn knob to
“1” after loading. Start drive and adjust knob until
pump primes and fluid begins to flow.
NOTE: Occlusion usually does not need to be
readjusted when changing tubing.
NOTE: After operation for some time, the retainer
teeth may scratch or mark the surface of the
tubing. This is normal and will not cause leaks or
otherwise reduce tubing life.
