These Cartridge Pumps are designed to provide up to 12 simultaneously driven pump channels and the ability to provide
nearly pulse-free flow. In addition, the pump systems incorporate the following features:
·
5:1 speed reduction on models 07519-15 and 07519-25, providing ultra-low flow rates.
·
12 cartridge capacity of models 07519-15 and 07519-25 permit dispensing simultaneously into 12 separate
containers with one set-up and pump cycle.
·
Six and eight roller designs provide reduced pulsation.
·
Elimination of “suckback” and greatly reduced pulsation by pairing cartridges with offset occlusion.
·
Low friction rollers for minimum abrasion of tubing.
·
Auto-resetting limit clutch built in to protect the Pump and Drive in case of excessive overload on models 07519-15
and 07519-25.
(1) Application Data
The six- or eight-roller Cartridge Pump Systems are designed for multi-channel use where low pulsation and/or close oc-
clusion control of a variety of different flows is required in low-flow applications. Tubing found in Table 3 can be used to
deliver from .6

min to 350 mL/min.
(2) General Description
Each Pump Head System (see Figure 1) is composed of a multi-roller Pump Head and two sizes of snap-in tubing car-
tridges, each with individually adjustable occlusion settings. The occlusion “wedge” design provides accurate and more
balanced flow control.
The Pump Heads contain either six or eight rollers. All models can operate with a variety of tubing. The six roller models
are compatible with the large cartridge and MASTERFLEX

thin wall tubing, and the eight roller models are compati-
ble with the small cartridge and .9 mm wall Microbore Tubing Sets (see Tables 1, 2, and 3).
The Pump Head Systems have an off-center occlusion path that allows two oppositely mounted cartridges to be con-
nected together for virtually pulseless flow with no suckback.
Both the six- and the eight-roller Pump Heads are available in two sizes. The short Pump Heads hold up to 2 large or
4 small cartridges and operate at the same speed as the drive. The long Pump Heads hold up to 6 large or 12 small car-
tridges and operate at one-fifth the speed of the drive.
Models 07519-15 and 07519-25 have an auto resetting limit clutch built in to protect the Pump and Drive in the event of an
excessive overload. When an overload occurs, the clutch emits an audible clatter indicating the pump rotor is not rotating.
The Pump Head quickly mounts to most existing MASTERFLEX
