Self Priming Air Driven Double Diaphragm Pump For Finished
Machining
Air Driven Double Diaphragm Pump Introduction
Air Driven Double Diaphragm Pump were designed to resolve numerous
problems that pumpers’ face on a job site. Whether you have limited
space, are moving fluids with mixed solids or compositions, or
require a safe priming pump system for your job, our AOD pumps
provide a portable solution to get the job done.
Operating through a dual-diaphragm fluid chamber, positive
displacement creates an air vacuum, initiating quick priming with
minimal effort. Once primed, air operated diaphragm pumps are
capable of passing up to 1-¼ inch solids (up to 90% solid
composition) and highly viscous fluids with ratings exceeding
25,000 cPs. AOD Pumps’ fluid handling, portability and durability
make them a versatile pump for any job application.
Air Driven Double Diaphragm Pump Features
| 1 | Ceramic material for main valve and reversing valve ensures longer
life, more stability and working in dirty compressed air ( most
occasions, air filter become option). |
| 2 | Without ice with the muffler. Innovative design with the exhaust
space of the pump, some of muffler inside, this makes the air
outlet smooth.) |
| 3 | Outward parts of the pump are all die casted aluminum and special
environment-protected painting, makes the pump with elegant
appearance. |
| 4 | Optimized design greatly reduces overall component number of pump.
Significantly improve performance, help for maintenance. |
| 5 | For power variety, pneumatic pump’s flow capacity normally lowers
than electric pump, but BSK pump is workable in series at certain
conditions. This can largely satisfy customer request. |
| 6 | Innovated design of sealing structure and material, totally solve
the leakage inside or outside. |
| 7 | BSK pump can be started with low air press ( only 1.5 KG air press
can start BSK pump). |

Air Driven Double Diaphragm Pump Maintenance
- Provide a clean work surface to protect sensitive internal moving
parts from contamination from dirt and foreign matter during
service disassembly and reassembly.
- Keep good records of service activity and include pump in preven
-tive maintenance program.
- Before disassembling, empty captured material in the outlet man
-ifold by turning the pump upside down to drain material from the
pump
