Note
The springs may come in different colorings. This is not a quality impairment.
Make sure to use the right spring strength. This can be identified by the spring
wire diameter. The standard version for Novoprene pump tubing (Part No.
90P1010) has a diameter of 1.1 mm and the reinforced version for FPM-,
Acidflex- or Masterflex-tubing (Part No. 90P1015) has a diameter of 1.2 mm.
Note
Two different types of springs are mounted inside the driver (right and left
springs) for the first delivery. When spare springs are ordered, for simplified
storage, only one type will be delivered (right spring) which can be used for all
four springs and will replace without any problems the initial springs. The
replacement springs guarantee full functionality when all four springs are
replaced.
Make sure that contact pulleys move easily on the axis. After remounting the axis with contact
pulley into the driver the spring has to be mounted as shown as in Figure 10. Please pay attention
to the alignment of the dent.
15.2.1 REASSEMBLY OF THE DRIVER
Reassemble the driver in reverse order:
Insert the roll carrier back into the pump head.
Push the pump head with the roll carrier onto the motor shaft .
Tighten the nuts of the pump head fastening (SW 5.5)
.
Note
While mounting, make sure that the center of rotation and the roll carrier (driver)
are aligned.
Make sure that the collar of the shaft bore (see figure 9) faces towards the front
of the pump head while mounting the roll carrier.
Use genuine spare parts only !
