Micro-Pump Selection Guide
Polymers referenced in this brochure:
EPDM = ethylene-propylene-diene
ETFE = ethylene tetrafluoroethylene
FEP = fluorinated ethylene propylene
FKM = fluorinated elastomer
FFKM = perfluoro elastomer
PEEK™ = polyetheretherketone
POM = polyoxymethylene (Acetal resin)
PPS = polyphenelyne sulfide
PTFE = polytetrafluoroethylene.
1. Select pump style; either Ported or Manifold mount and work from the appropriate table:
·
Ported for direct connection with
1/4
”-28 fittings (
5/16
”-24 for 150SP
)
·
Manifold mount for use with manifolds (see page 13)
Then:
2. Locate the volumetric characteristics that best suit your needs
3. Choose your preferred body material depending on the level of chemical inertness you require
4. Turn to the pages indicated to see full details and ordering information for each pump.
