INTRODUCTION AND GENERAL DESCRIPTION
This EASY-LOAD Pump Head when combined
with a MASTERFLEX®I/P®drive or compatible system 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 hardware 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.

MULTI-CHANNEL MOUNTING
I/P EASY-LOAD Pump Heads can be mounted in
tandem depending upon the torque capabilities of
the drive. A standard short shaft pump head is
required for the add-on head along with special
mounting hardware. (See Figure #5.)
See REPLACEMENT PARTS AND ACCESSORIES for
mounting hardware.
CAUTION: DO NOT OVERTIGHTEN
SCREWS OR WING NUTS.
NOTE: The I/P EASY-LOAD Pump Head can be used
in any combination with other 7019-series
Pump Heads.
NOTE: The tubing on the inside EASY-LOAD Pump
Head can be changed without removing the
outside pump head.
