We are offering air operated double diaphragm pump. These pumps are very easy to use and no skilled persons are needed to operate or repair the pump. The
air operated double diaphragm pumps can also be used as metering pump with accuracy up to 3-5%. In a nutshell, it is a very simple and versatile pump. Standard aodd pumps are 1:1 ratio so that maximum outlet pressure never exceeds air supply pressure.
made of - polypropylene (pp)
- polyvinylidene fluoride (pvdf)
- stainless steel
- aluminium
- cast iron
functioningair operated double diaphragm pump (aodd) is a double pump with two chambers filled and emptied by drawing liquid through a common inlet and discharged through a common outlet. The diaphragm in each chamber is connected by a common shaft so that they move backwards and forwards together. Compressed air is directed by the air valve alternatively behind each diaphragm to power discharge strokes. Pump speed and there fore fluid flow rate can be infinitely controlled by increasing or decreasing air pressure and or volume.
advantages - no seal, leakage, motor, fire, rotation, or charging
- less wear and tear
- self priming
- no foot valve needed
- pump can run dry
- variable flow with the same pump
- stop automatic on closing of discharge valve
- light weight
- handy in use
- can be submerged easily
- less stock of spare parts
