High Pressure Air Driven Double Diaphragm Pump For Foodstuff Pharmaceutical
High Pressure Air Driven Double Diaphragm Pump For Foodstuff Pharmaceutical
What are Air Driven Double Diaphragm Pump ?
These are pumps without any electrical motor and run with an air pressure ranging from 1.3 to 8.0 bar. They are simple to run with minimum maintainance cost and down time. All type of liquids can be pumped. Only the MOC and capacity of pumps will vary depending on application and buyer requirements. Sizes vary from 1/4" to 3" and they are available in PP, PVDF, SS & Aluminium Models.

General Description
Requirements for Air and Lubrication
EXCESSIVE AIR PRESSURE. Can cause pump damage, personal injury or property damage.
- A filter capable of filtering out particles larger than 50 microns should be used on the air supply. There is no lubrication required other than the “O” ring lubricant which is applied during assembly or repair.
- If lubricated air is present, make sure that it is compatible with the “O” rings and seals in the air motor section of the pump
