REPLACEMENT PARTS AND ACCESSORIES
Mounting Plate Kit for L/S EASY-LO AD 3 P ump Heads: 77800-00
Kit contains (4) 8-32 screws and the mounting plate.
This kit adapts the EASY-LOAD 3 Pump Head to MASTERFLEX L/S pump drives.
INTRODUCTION AND GENERAL DESCRIPTION
This L/S®EASY-LOAD®3 Pump Head, when combined with a MASTERFLEX L/S drive or
compatible system, is designed to provide a simple, easy-to-use peristaltic pump system.
The Pump Head accepts several different tub ing sizes for a wide range of flow rates. The
unique lever actuator design and automatic tubing retention allow quick tubing changes.
This pump is designed to transfer or dispense liquids of various viscosities, as well as solids
suspended in liquids. It is NOT intended to pump flammable or explosive substances.
A mounting kit adapts this pump to MASTERFLEX L/S drives. The kit includes a mounting plate
and four screws, which are used to attach the mounting plate to a drive. Pumps are easily
and quickly attached to the mounting plate, or another pump, by means of the bayonet feature
on the back of the pump. The pump may be mounted with tubing entering and exiting to the
left, right, up or down. Mounting orientation options may be limited with some drives. Pumps
are just as easily removed, using the one-finger release lever on the upper left side of the
pump. The tang on the pump shaft couples the pump to standard MASTERFLEX drives, for
power transmission.
Each pump is supplied complete with a 17-inch (43-cm) length of tubing, one mounting kit and
this manual. A Phillips screwdriver is required to complete installation.

CAUTION:
Be sure that bayonet features on back of eac h
pump are fully engaged with bayonet tabs on
front of mounting plate or adjacent pump front
before operating pump. Bayonet lock lever
(see Figure 5) will snap back when bayonet
features engage completely.
NOTE: The tubing on the inside L/S EASY-LOAD 3 Pump Head(s)
can be changed without removing the outside Pump Head(s)
from the drive.

MULTI-CHANNEL MOUNTING
L/S EASY-LOAD 3 Pump Heads can be mounted in tandem (up to three), depending on the
torque capabilities of the drive. (See Figures 8, 9 and 10.) Once the mounting plate is
attached to a drive, no other mounting hardware is required. To use 4 pumps on one drive,
call dealer for recommendations.
To install a second pump, the cosmetic cover must be removed from the first pump.
Grasp the cover by the notches and pull it off. (See Figure 8.) Align the second pump
to the first, as if the first pump were a drive. Follow single pump mounting instructions
in ”INSTALLATION AND REMOVAL“. (See Figures 9 and 10.)

INSTALLATION and REMOVAL
Attach the mounting plate to the MASTERFLEX drive, with the four Phillips head screws provided
in the mounting kit. (See Figure 1.) Orient the pump with its back facing the drive. Insert the tang
on the pump shaft into the slot in the shaft on the drive. Align the bayonet features on the pump
back with the bayonet tabs on the front of the mounting plate. (See Figures 1, 2 and 3.) The pump
should be tilted about 30 degrees counter-clockwise from the intended installed orientation.
Finally, press the pump firmly against the drive and rotate clockwise, until no more rotation is
possible (about 30 degrees). (See Figure 4.) The bayonet lock lever will snap toward the back
of the pump and automatically lock the pump to the mounting plate.
To remove the pump from the drive, pull the bayonet lock lever forward. Hold the lever forward
while rotating the pump as far counterclockwise as possible (approximately 30 degrees).
Then pull the pump away from the drive. The actuator lever should be in the far right position
when removing the pump. (See Figure 5.)
WARNING: Stop the drive be fore ins talling or removing
the pump from a drive

TUBING LOADING and UNLOADING
To load tubing, open the pump by moving the actuator lever counterclockwise (left, if pump is
mounted vertically). (See Figures 5 and 6.) Insert a loop of tubing into one open tubing
retainer, between the occlusion bed and the rollers and into the other tubing retainer. (See
Figure 7.) Position the tubing so that it is firmly against the rollers and centered on the length
of the roller. While holding the tubing ends, move the actuator lever back to the far clockwise
(right) position, as shown in Figure 5. The pump will automatically grip the tubing. Tubing sizes
L/S
®
13, L/S®14, L/S®16, L/S®25, L/S®17 and L/S® 18 (thin wall) will automatically be
stretched by the pump. Approximately 5 pounds of force must be applied to the actuator lever
to fully close the pump and place the lever in its locked position (far right position) or to fully
open the pump (far left position). NOTE: It is not necessary to have an end of the tubing free to
load or unload tubing from the pump. A length of tubing, attached to other devices, may be
loaded into the pump, without disconnecting the tubing from adjacent devices.
WARNING: Stop the drive be fore ins talling or removing
tubing from the pump.
