Air operated diaphragm pumps



In the food industry are liquids for the final product stocked in 200 l - barrels. If this liquids have viscosities of 15.000 - 20.000 mPas it is technical difficult, to pump these fluids with a standard drum pump and to handle with a plunger piston.

Different inconveniences are possible, depending to the viscosity:

The outlet pressure is getting higher. The fluid forms a cone in the middle of the drum which is more difficult to pump than the liquid in the outside section.

The solution for all this difficulties is the application of a high-pressure drum pump. The high pressure allows a transfer of the viscous fluid without any problems. Die platform is fortified by 2 winches which have the function to increase the pressure on the surface of the drum. So the viscous liquid moves to the surface.

For a smoothly pumping procedure in the food and chemical industry the cleaning and maintenance of the installations is very important. For these purposes Techni-Flow provides you with a product range of chemical drum pumps of polypropylen for the transfer of cleaning supplies on natron basis. Further we dispose of chemical drum pumps of PVDF which are suitable for the transfer of chemical fluids based on nitric acid. Furthermore you can transfer with our drum pumps in steel-alloy these both aforementioned liquids.
