The springs may occur in different coulerings. This does not constitute a
quality defect. But make sure that the right spring strength is used. This
can be identified by the spring wire diameter. The „standard version for
Novoprene pump hoses“ (part no. 90P1010) has a diameter of 1,1mm and
the strengthened version for FPM-, Acidflex- or Masterflex-hoses“ (part
no. 90P1015) has a diameter of 1,2mm.
N O T E !
At first delivery two different types of springs are mounted in the driver
(right and left springs). When spare springs are ordered, for simplified
storage only one type will be delivered (right spring) that can be replaced
without any problems and guarantees full functionality when all four
springs are replaced.
 Make sure that contact pulleys roll easily on the axis. After remounting the axis with contact
pulley into the driver the spring has to be mounted as shown in Figure 8. Please pay attention
to the alignment of the dent.
 Remounting happens in reverse order.
N O T E !
While mounting pay attention to the fit of ‘rotational axisdriver’ and
check that the plunged boss at the shaft bore points to the front of the
pump head.
Use genuine spare parts only !
