When Choosing a spray system, material type is very important. Every job has its own special needs with its own chemistry. When considering costs, some important factors to consider are wear and maintenance.
Transland pumps and valves made from aluminum will work fine for many jobs, yet they may be more costly in the long run when adding in the cost of maintenance or replacements
Alternative Stainless steel parts from Transland may cost a little more up front but will last longer and save you time and money in the long run when well maintained.
