Pneumatic Polypropylene Diaphragm Pump Air Operated 44L/Min 6.9bar
Air diaphragm pump
(also know as a Membrane pump, air operated double diaphragm pump(AOOD)or pneumatic diaphragm pump)that uses a combination of the reciprocating action of a
rubber,thermoplastic or diaphragm and suitable valves either side
of the diaphragm (check valve,butterfly valves,flap valves,or any
other form of shut-off valves) to pump a fluid.

General Description
The diaphragm pump offers high volume delivery even at low air
pressure and a b road range of material compatibility options
available.Refer to the model and option chart.The pump is provided
with the modularized air motor and fluid section.
The air operated diaphragm pump alternately generates the intake
fluid pressure and positive fluid pressure in the fluid chamber by
using the pressure difference in the air chamber. The ball valve
can ensure the forward flow of fluid.
Pump cycling will begin as air pressure is applied and it will
continue to pump and keep up with the demand. It will build and
maintain line pres -sure and will stop cycling once maximum line
pressure is reached (dis -pensing device closed) and will resume
pumping as needed.
FLUID SECTION DISASSEMBLY
Remove the upper and lower manifold (1) and (11).
Remove the ball (2), “O” ring (3) (47) and ball seat (4).
Remove the fluid cap (5).
NOTE: Only diaphragm models use a primary diaphragm(6A) and a
backup diaphragm(6). Refer to the aux iliary view in the Fluid
Section illustration.
Remove the screw (10), washer (9), diaphragm (6A, 6) and diaphragm
washer (7, 8).
NOTE: Do not scratch or mar the surface of (23) diaphragm rod.
FLUID SECTION REASSEMBLY
Reassemble in reverse order.
Clean and inspect all parts. Replace worn or damaged parts with new
parts as required.
Lubricate (23) diaphragm rod and 25) “Y” ring with grease.
Fix the diaphragm rod (23) with the auxiliary installation tool.
Prior to the final fastening of bolts and nuts, please determine
whether the diaphragm (6A,6) is aligned with the fluid cap (5)
properly to avoid the twisting of the diaphragm.
For the models using diaphragm: three rubber diaphragms (6) on the
side, which are marked with AIRS SIDE "air chamber" are mounted in
face of the pump body.
Start the pump, check the fastening and sealing after it runs for a
period of time.
