Installation Versatility

The AirTECH Air-Operated Double Diaphragm Pumps (AODD Pumps) are designed and customized for many kind of application. Here you can find the main examples of installation.

Positive Suction

That’s a typical application for viscous fluids where the suction side of the Air-Operated Double Diaphragm Ppump is under the fluid’s level and the pump draws from the bottom of the tank.

For safety reason it is suggested to restrict the inlet fluid pressure as following: 0,5 bar for PTFE diaphragm’ pumps and 0,8 bar for Rubber diaphragms’ pumps.

Moreover, it is important to install a check valve between the suction side of the pump and the tank in order to avoid the dispersion of the liquid in case of breakage of the diaphragms.

Negative Suction

This is the standard application for Air-Operated Double Diaphragms Pumps considering their self-priming ability. The AirTECH Pumps can be used for emptying drums and wells or others applications where the suction side of the pumps is over the liquid’s level of the tank.

For this kind of applications is important to know well the pumping fluid especially the specific gravity and the viscosity and the plant conditions because the self-priming ability can change depending of this factors. Please contact us for a free technical support!

Submerged

AirTECH Pumps are completely submersibles. In this case, the pump is located inside the tank in contact with the pumping fluid. For this reason it is important that all the materials of construction submerged in the liquid have a perfect chemical resistance and compatibility.

Moreover, for submerged applications it is necessary that the air exhaust is over of the fluid’s level; therefore it is important to install an extension to the exit connection of the air exhaust in order to be port it on the top of the tank. Please contact us for a free technical support!

Double Suction

Available on request AirTECH Pumps are available in double suction manifold. This special version is used for application where is necessary to mix two different liquids. In this way you can make it using just one pump. Please contact us for any information or quotations request!

Double Discharge

Another special model available on request is the pump with double delivery manifold. It can be used for application where is necessary to deliver the same product in two different part of the plant.

AirTECH pumps offer you the solution to make it using just one pump. Please contact us for any information or quotations request!

Double Suction & Double Discharge

This is the last one special model of AirTECH pumps where you have both double suction manifold and double discharge manifold. In this case you have two different side totally independent where you can pumping two different liquids with any contact each other.

Also here AirTECH Pumps offer you the opportunity to do it using just one pump. Please contact us for any information or quotations request!
