2.2.3 Special Information for Biocompatible Pumps
The UltiMate 3000 pump series includes the following biocompatible pump types:

LPG-3400BM

DGP-3600BM

ISO-3100BM
Except for the fluid components, the BM pumps are identical to the SD and RS pumps.
Therefore, almost all descriptions in this manual apply also to the BM pumps. If some detail
applies to only one pump type, the type will be identified by name. The differences are as
follows:
The fluid components are made of titanium. Titanium is a base material, similar to aluminum
and magnesium. When titanium is processed, a titanium oxide film builds up on the
component surface, ensuring excellent corrosion resistance. The color of titanium and stainless
steel is slightly different. In addition, titanium parts are lighter than parts made of stainless
steel. Nevertheless, you can easily confuse titanium with stainless steel parts.
Observe the following:

When substituting parts be sure to install the appropriate replacement part for the BM
pumps. For information about the part numbers and for installation details, see the related
service sections (

page 123 and following pages) and the Consumables and Spare Parts
section (

page 199).

When connecting the solvent reservoirs, make sure to use appropriate filter frits on the
end of the solvent lines (shipped with the pump). As a standard, filter holders with
stainless steel frits are provided in the accessories kit of the SRD-3x00 Solvent Racks of
the UltiMate 3000 system. Replace the stainless steel frits with the frits from the
accessories kit of the pump (

page 48).

Ring seals with a titanium spring are installed as piston seals in the biocompatible pumps,
whereas common ring seals with a steel spring are used in the SD and RS pumps.
Therefore, do not confuse these seals.
