Maintenance Fluids

Using the right Maintenance Fluids is the secret to keeping your airless sprayer running like a well-oiled machine! The number one benefit is protecting your investment. Fluids like Graco's Pump Armor are specifically designed to prevent corrosion and freeze damage inside your pump when it's in storage. This simple step can save you from seriously expensive repairs and ensure your sprayer is ready to go when you are.

Another huge benefit is performance. Using a dedicated throat seal liquid (TSL) is absolutely vital for keeping the packings on your pump lubricated. This reduces friction, prevents paint from drying on the piston rod, and extends the life of your most critical wear parts. Forgetting this can lead to premature wear and costly downtime. Using genuine Maintenance Fluids is the easiest and most effective way to protect your equipment, save money on repairs, and guarantee your sprayer performs flawlessly on every job.

That's a vital question because Pump Armor plays a unique and non-negotiable role in protecting your sprayer! While other Maintenance Fluids like TSL are for daily lubrication, Pump Armor is your go-to storage solution. Its primary job is to protect the inside of your pump from corrosion and freeze damage when the machine is not in use, whether that's overnight or for several months.

After cleaning your sprayer, you simply circulate Pump Armor through the system until it comes out of the gun. This displaces any remaining water and coats the entire fluid section with a protective, anti-corrosive film. This single step prevents rust from forming and stops any trapped water from freezing and cracking the pump in cold weather. Think of it as putting your pump into hibernation safely. Using it every single time you store your machine is the best insurance policy against premature wear and tear, ensuring your sprayer is always ready for the next job.

Using Throat Seal Liquid (TSL) is the single most important daily habit for any sprayer operator! TSL is a specialised lubricant that you apply directly to the piston rod of your airless pump. Its one and only job is to lubricate the packings—the seals that the rod slides through. Without it, friction from the piston's rapid movement can cause paint to dry onto the rod. This dried paint then gets dragged through the packings, shredding them and causing premature wear.

A few drops of TSL before every use, and after any long break, creates a wet barrier that stops paint from sticking and keeps everything moving smoothly. This simple, five-second step is the difference between packings that last for hundreds of hours and ones that fail after just a few jobs. Among all the Maintenance Fluids, TSL is the one that prevents the most common and frustrating cause of sprayer downtime.

For hydraulic-powered sprayers, the right oil is everything! Using the correct Hydraulic Oil is absolutely critical for the performance and longevity of machines like the Graco LineLazer V HP Automatic. Unlike airless pumps, these units use a hydraulic system to drive the paint pump, and that system relies on a specific type of oil to function properly. Using the wrong fluid can lead to overheating, poor performance, and even catastrophic failure of the hydraulic motor.

The correct Hydraulic Oil provides the perfect viscosity for smooth operation, protects against wear, and helps dissipate heat. It's one of those essential Maintenance Fluids that you simply can't compromise on. Sticking with the manufacturer-recommended oil ensures your machine's hydraulic system runs exactly as it was designed to, giving you consistent power and reliability job after job. To keep your hydraulic sprayer in peak condition, make sure you're using a high-quality, compatible fluid.
