AODD pump is a pneumatic device with high efficiency, which can transport high temperature media up to 150 ℃, and can be used for recovering and recycling of hot water, loading or unloading takers and oil depots.
Features
- Pneumatic dual diaphragm pump can transport high temperature media up to 150 ℃.
- Adopt pilot operated type air valve to eliminate the AODD pump downtime and extend its life span.
- It is designed with multiport to help you install it easily.
- Air powered diaphragm pump can be used as a movable-type material transfer pump because it has such advantages as small in size, easy moving, no need base, small occupied area and easy installation.
- It can be externally connected to an electromagnetic valve for remote control. And the reversing valve requires no lubrication.

Applications

Tips: Why does the pressure of the air operated diaphragm pump drop suddenly?
- Caused by insufficient fuel supply. It is recommended to repair the fuel valve in time.
- The material has not reached a certain amount when the material is being fed, or there is an oil leakage phenomenon, it is necessary to check the actual situation of the material in time to control the oil leakage.
- The pneumatic diaphragm pump has no action, or the action is very slow. This situation may occur because the air valve is stuck, and the air valve is worn. If the air valve is stuck, clean it in time. You can use a certain cleaning agent. If the air valve is worn, replace it with a new one.
