Air Operated 3 Double Diaphragm Pumps by Hydrotherm Engineering Services

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
