All About Transfer Pumps: How Pumps Work and Common Pump Problems

Transfer Pump failure is one of the leading causes of off ratio incidence, lost production time, emergency, and cost over-run out of the many components that make up our processing equipment. Diligent preparation is a key factor toward the successful operation of your project and the equipment you depend on. The facts is, equipment components are only going to perform as well as they are understood and maintained.

How to Select a Polyurethane Spray Gun

Spray polyurethane foam is an essential component used by the manufacturing and construction industries. The key to multi-tasking, spray foam is used as insulation across a variety of applications, including walls, roofs, and ceilings, and is even used in industrial settings between pipe fittings or in climate controlled environments. The spray foam formula can be altered to suit different uses, depending on the needs of the application.

Choosing a Screen

Machine screens and spray gun screens come in three different sizes; 80, 60, and 40 mesh. Using a larger mesh filter allows smaller particles to pass through your processing system and out the spray tip of the gun. For most polyurethane foam and polyurea, I suggest using 60 or 40 mesh screen to reduce filter clogging.

Cleaning A/B Filters

Sometimes chemical cleaning the A and B filters can leave too much residue and plug up the screen hole. My suggestion? Re-new your filter screens.

You can do it with a few tricks. Try using a light amount of heat from a torch and burn out any restrictions. Once the restrictions are burned off, use air to blow out excess from the screens. Finally, hold your screen up to a light to ensure it is clear and ready to use again.
