Tip : Never reassemble the pump head with bare hands. Put on a pair of clean room
gloves to prevent contamination on the pump parts. Even minute particles may
cause damage to the system and result in poor pump performance.
1. Depends on the pump type
RS and SD pumps
With these pumps, the support ring is not a wear part. Thus, you need not replace the
support ring when you replace the piston seal. However, before reinstalling the support
ring, you should clean the support ring from the inside and outside, using isopropanol, a
cleaning swab (part no. 6040.0006), and a lint-free cloth or tissue.
BM pumps
With these pumps, you should always replace the support ring whenever you replace the
piston seal.
2. Pipette a few drops of isopropanol onto the edge in the pump head on which the piston
seal will rest.
3. First, slide the support ring, and then slide the piston seal onto the seal insertion tool
(

Fig. 40, page 140). Mind the correct orientation of the seal. The open side of the
seal must face away from the tool.
