Industrial Acid Diaphragm Pump / Self Priming Low Pressure
Diaphragm Pump
Acid Diaphragm Pump Introdution
(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.
| Item | Description | Unit | Reference Figure |
| 1 | Maximum air inlet pressure | Mpa | 0.6 |
| 2 | Maximum flow rate | 1/Min | 27 |
| 3 | Maximum lift | M | 45 |
| 4 | Maximum outlet pressure | Mpa | 0.6 |
| 5 | Maximum particle size | mm | 1 |
| 6 | Weight | kg | 1.8 |
| 7 | Noise level | db | ＜68 |
| 8 | Max dry suction | m | 4.2 |
Main Advantages
1, Due to the use of air power, the flow automatically changed
according to export resistance. Which is suitable for high
viscosity fluid.
2, In inflammable and explosive environment, the pump is reliable
and low cost, won't produce spark and not overheat,
3, The pump volume is small, easy to move, no foundation needed,
convenient installation and economy. Can be used as mobile
conveying pump.
4, Where there are dangers, corrosive materials processing,
diaphragm pump can be separated completely with outside.
5, The pump shearing force is low, physical effect to medium is
small, can be used for conveying unstable chemistry fluid.
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.
