An Air-Operated Double-Diaphragm pump (AODD) is a type of positive displacement (PD) pump. It consists of two pumping chambers that are alternately filled and discharged by the movement of flexible diaphragms. Compressed air is alternately fed to, and vented from, air chambers on the opposite sides of the diaphragms to create the pumping action.
Page 5 CAUTION Dynapump LE Series are canned motor, sealless pumps that offer a low cost, off the shelf, environmentally friendly alternative to sealed and single containment sealless pumps. Care should be exercised upon installation, start up, removal and maintenance of the pumps. Recommended safety equipment should be used at all times.
Vacuum loaders are the simplest version of a 'resin conveying system' but they are not an integral part of a central conveying system. Self-contained vacuum loaders are used to transfer pellets, regrind and powders from a single source (usually a Gaylord) to a single destination (usually a blender, drying hopper or machine throat).
A safety relief valve is installed in the first tank the air compressor pumps air into. The safety valve protects the tank and the rest of the system from too much air pressure. The valve is usually set to open at 150 p.s.i. ( kPa) Brake pedal: The brakes are applied by pushing down the brake pedal (also called the foot valve or treadle valve).

The gouged area is also much cleaner after using an air carbon arc torch. Grind all surfaces smooth. Inspect the hooks (1). Note: The hooks are shipped with braces that hold the hooks in position during installation. Do not remove the braces until the installation process is complete. Note: Braces have been tack welded to the hooks. The braces.

· An argument could be made that the most important element to implementing an effective heat-trace system is attention to detail during the installation. There are a multitude of factors at play when installing heat trace, and each must be carefully considered. Too often, heat trace is installed improperly or in an inconsistent manner, resulting in a system that is more prone to failure.

· For most systems, the installation process is a matter of placement, connection, and operation. Placement of the accumulator in the system is generally specified by the system designer. In these cases, the installer should take a reality check to make sure the selected location is feasible.
Air can sometimes be sucked into a pump through failing valves or other weak points such as joint rings. Once inside, the air has nowhere to go but along for the ride. As the liquid is swished around, the air forms bubbles which then gets popped under pressure by the impeller. Symptoms of Cavitation.
The process pump takes the chilled glycol from the tank, to the process cooling application, and returns it to the glycol stor-age tank. This pump does not need to be running in order for the chiller to operate. Our smaller ChilStar chiller systems do not have a glycol process pump, we utilize a single pump for supplying the glycol to the plant.
