Double Diaphragm Pumps
are designed for use in
applications requiring large
volume transfer in a short time
Driven by compressed
air, these can transfer
contaminated media & are
very useful for cleaning out
pits with mixed liquids such as
oil, water etc.
Handle a wide variety of fluids
with solid content: as there
are no close fitting or rotating
parts
Self priming: pump is designed
for high suction lift even at dry
start up & also with heavier
fluids
Ability to run dry: as there are
no close fitting or sliding parts
Portable / simple installation:
Simply connect air supply line
& liquid line; pump is ready to
perform
Explosion proof: safe pumps
since they are operated by
compressed air
Pumping efficiency remains
constant: no rotors, gears
or pistons that wear over
time, hence no decline in
performance
All pump models are designed
for use with an inlet air
pressure of 20-100 PSI
Air inlet threaded 1/4" NPT (F)
Standard off the shelf pumps
are available in a choice of 2
materials:
i. Aluminium body with a
Hytrel* diaphragm. These
can be used for all high
temperature applications
ii. Polypropylene - body with
a. Santoprene Diaphragm
- for use with abrasives,
acids, caustic etc.
b. Teflon (PTFE) Diaphragm -
for use with fluids such as
solvents
