SETUP

Two cartridge sizes (0.72 in and 0.36 in thick) (see Figure 3) accommodate a broad range of tubing sizes, as noted in
Tables 1 and 2.
FIGURE 3 SMALL AND LARGE CARTRIDGES

(1) Select Cartridges

NOTE: These Pump Heads are designed to work with the Model 07519-75 and 07519-85 Cartridges. Do not use Model
07519-70 or 07519-80 Cartridges, which are designed for different Pump Heads.
Depending on which Pump Head is used, up to six large or twelve small tubing cartridges can be teamed up with the
Pump Head. But there is a limit, depending on available drive power and pump load. For full tubing flow rates at 0 psi, Ap-
pendix B shows cartridge capacities according to tubing size and drive Type (see Appendix A for description of drive
types). Cartridge sizes can be intermixed on the six-roller pump as long as the total load does not exceed the drive
capability.
® ® ®
The small Cartridge is designed to operate with MASTERFLEX Precision Tubing sizes L/S 13 and L/S 14 in either
six-roller pump head and will also accommodate specially designed Microbore Tubing Sets (.9 mm wall) when used in one of
the eight-roller pump heads.
® ® ® ® ®
The large Cartridge is designed to operate with MASTERFLEX Precision Tubing sizes L/S 14, L/S 16, L/S 25 and L/S
17 in either six-roller pump head.
Use only MASTERFLEX Precision Tubing and Microbore Tubing Sets with
MASTERFLEX pumps to ensure optimum performance.
Use of other tubing may void applicable warranties.

(2) Load Cartridges

The Cartridges' occlusion surfaces are positioned asymmetrically around the pump roller assembly (see Figure 3), so
orientation on the Pump Head may be important for certain applications.
To achieve parallel, synchronized pulsations and fluid "pillows" through all channels, orient Cartridges in the same
direction.
To achieve nearly pulseless flow, install Cartridges in alternate directions and connect equal lengths of tubing from the
discharge side of two alternate cartridges together through a Y connector as shown (see Figure 4). The asymmetric de-
sign of the cartridges provides overlapping pulses through the two tubings, which act to almost completely cancel pulsa-
tion in the combined flow channel.
NOTE: The joined flow rate will be greater than the single channel flow rate for any given tubing size and pump speed.
