Have you ever wondered: when should you choose a paint pump or a pressure tank? Paint pumps and pressure tanks are important pieces of equipment in the professional painting industry. Both offer several advantages that you should consider, depending on your situation, before choosing which one to implement in your painting process.
By choosing the right equipment configuration, you can maximize efficiency, finish quality, and production. Below, we'll review paint pumps and pressure tanks so you can decide which might be the right choice for your painting and coating application needs.
Pressure tanks
You pressure tanks They use internal air pressure to push the paint into the gun, where the paint particles are broken down by pressure in the air cap. Available tank models have internal capacities of 2, 10, and 20 liters, with the latter two configurations featuring a pneumatic agitator that maintains paint homogeneity during application. Equipment such as pressure tanks is widely used in small businesses to optimize time and finish quality.
Depending on your needs, you can use 2 to 4 paint guns at the same time. However, it is recommended to purchase an extra tank to avoid production interruptions in the event of problems with the main tank.
Paint pump
Paint pumps are divided into two models:
Low-pressure pumps, commonly known as diaphragm or diaphragm pumps, use diaphragms to deliver paint to the spray gun, where paint particle breakage and atomization are also achieved by pressure in the air cap. This configuration can be used with conventional, HVLP, and LVLP spray guns.
And finally, high-pressure pumps or piston pumps, widely used in the furniture and metalworking industries for equipment with Airmix technology, which significantly reduces the overspray generated by spray guns during painting. This technology uses 70% of mechanical pressure and 30% of compressed air to spray the paint.
But after all, which model is best suited: pressure tank or paint pump?
Regardless of the advantages of each, it's essential that a technician evaluate the painting process as a whole, as process variables will determine the most appropriate equipment, both in terms of productivity and financial return. The ArpiAspersul Group has a team of highly qualified technicians to evaluate your painting process and advise you on the best choice.
