Santoprene
®
Injection molded thermoplastic elastomer with no fabric layer. Long mechanical ex life.
Excellent abrasion resistance.
Hytrel
®
: Good on acids, bases, amines and glycols at room temperatures only.
Polypropylene
PVDF
Virgin PTFE Chemically inert, virtually impervious. Very few chemicals are known to react chemically
with PTFE: molten alkali metals, turbulent liquid or gaseous uorine and a few uoro-chemicals such
as chlorine triuoride or oxygen diuoride which readily liberate free uorine at elevated temperatures.

MODEL PB¼-A Performance Curve
Performance based on the following: elastomer fitted pump, flooded suction, water at ambient conditions.
The use of other materials and varying hydraulic conditions may result in deviations in excess of 5%.
(SANDPIPER
®
pumps are designed to be powered only by compressed air)
CAUTION: Nonmetallic pumps and plastic components are not UV stabilized. Ultraviolet
radiation can damage these parts and negatively affect material properties. Do not expose
to UV light for extended periods of time.
See page 2
for ATEX ratings.
See pages 2, 13 and 14
for ATEX ratings.
Maximum and Minimum Temperatures are the limits for which these
materials can be operated. Temperatures coupled with pressure affect the
longevity of diaphragm pump components. Maximum life should not be
expected at the extreme limits of the temperature ranges.
