The basic components of the airless paint sprayers are a fluid pump, high pressure hose, airless spray gun and airless tip.
There are two pump types, piston pump and diaphragm pump. Both work very well. But the diaphragm type won’t be able to pump the Very Thick materials like a piston pump can.

Normally many people like airless paint sprayers of piston pump types. but we do recommend our diaphragm pump type also, because their quality are really very good.

•A piston pump has many components including a piston, V packings, and spray valves. The piston moves up creating a vacuum to suck up the paint into a chamber, the fluid section, and piston down to push the paint into a high-pressure hose.

The V- packings create a seal to prevent pressure losses during the painting operation. Professional airless paint sprayers use self-adjusting V-packings to prevent premature wear and the need for repairs.
Check valves, or ball and seat valves, direct the flow of painting material from the fluid section of the pump to the hose. This prevents the paint from being pumped back through the pick-up tube.

All piston pumps have these components in one form or another.

•A diaphragm pump also uses a piston, but in a different way. The piston moves hydraulic fluid to move the diaphragm, which in turn sucks up the paint and then pushes it through the hose and gun.
No moving parts touch the diaphragm. The movement of the piston and hydraulic fluid cause the diaphragm to move up and down very rapidly.

There are no packings with this design, but check valves are still necessary.

High-pressure hose is necessary for this application method also.

This hose is rated for the maximum output pressure of the pump; 3000 psi is the typical operating pressure.

The attached fittings are ¼ inch and will work with most units. This is very tough hose that is kink resistant and capable of withstanding very high pressure. normally its bursting pressure could be reaching 10000psi or so. it’s a nylong inner tube with 2 layers of fiber braided hose and then wraped by polyurethane.

Never attempt to repair this hose as personal injury could result. It is better to replace than repair.

Airless Spray Gun

The airless spray gun is a valve that is used to control the airless paint sprayer and hold the tip. With a handle and trigger it resembles a handgun.
When the trigger is pulled the valve is opened and paint is allowed to travel to the tip and finally to the surface being painted.

Comfort is a big factor in choosing the right spray gun.

We produce 2 and 4 finger guns like our DP6376 Which is a copy of Graco SilverPlus gun. The numbers, 2 or 4, refers to the amount of fingers needed to pull the trigger.

Some people like the 2 finger airless spray guns for their comfort and balance. Choosing a spray tip is difficult and depends on the capabilities of your pump and the material being sprayed. This choice will affect the performance and effectiveness of your airless paint sprayer.

These are the basic components of all airless paint sprayers. The type you choose to own will depend on your expectations and needs. Remember the thicker the material to be sprayed the more power you will need.

Crowder Painting owns a variety of professional airless pumps including,

Graco 695 This is an excellent piston pump that is very powerful and capable of performing almost any paint spraying task. we’re developing another machine which is similar to this item also. it will be ready next year.

You can still paint your house via the traditional paintbrush and roller, but airless paint spray system can cut your painting time in half.
Air spray guns are mostly powered by compressed air, it has big noise, and it can’t spray high viscosity coatings. but “airless” sprayers are also available. The sprayer is considered “airless” because the electric turbine creates a high pressure ( about 210bar ) within the pump mechanism to push out paint . and the paint will be automized or exploded at the nozzle .
the advantage of airless painting is as below
1. the perfect painting finish
if you use the paint roller or paintbrush, the wall will not be so smooth , even though you use the best quality paints , the result is not so good.
but if you use airless painting equipment, the high pressure will automize the painting into very small particles, and drop them onto the wall, the final surface will be very smooth and tight.
2. high efficiency
The air spray gun could spray 30 – 100 square meters per hour
but airless spray guns can painting 300 – 1500 square meters per hour
so it will save much of your working time
3. improve the adhesion of the coating, and prolong the lifetime of the painting
the airless paint sprayer will make high pressure of 3000psi or more, it will give the small paint particles very strong power to sink into the wall.
that’s meaning the coating particle will combined hand by hand with very strong adhesive.
and you can spray high viscosity coating without too much water.
if you use paint roller, you can’t paint the strong coating unless you put too much water for dilution.
4. if you use airless spray coating, you can save 15% – 25% coating
because when you use the paint roller, the coating finish is not smooth or equal everywhere.
but if you chose airless painting, all the place will be same thickness.
5. you can use airless system to spray into any corner , angle , cant ……
6. Easy using, and low noise.
you don’t need to buy an air compressor for power the air spray gun,
now you just need to put the plug into the cable socket, then connect all the machines + hose + guns , and you can spray immediately after the prime recycling.
The prime return valve is just to ensure to exhaust all the air inside the hose and pump body.

but because of the sales strategy of HONDA group, we can’t equip it for all countries marketing
some country is not allowed to equip it for our machine
so we will chose YAMAHA or maybe A Chinese famous local brand for example ZONGSHEN motor instead.
but we can ensure you the quality is very good also.

Airless paint sprayers are one of the best inventions of all time. Only the brush and roller can be considered more important.

Airless sprayers can apply a wide range of coatings and finishes in less time than any other application method. Plus apply the coating at any thickness desired.
Airless paint sprayer refers to a method of applying house paint at high pressure to atomize the paint. This method works by forcing the paint, or primer, through a small tip opening at very high pressure.

Airless sprayers do not use compressed air.

The basic components of the airless paint sprayer are a pump, hose, gun and tip.
There are two pump types, piston and diaphragm. Both work very well. But the diaphragm type won��t be able to pump the very thick materials like a piston pump can.

The most versatile airless paint sprayers are the piston pump types.

A piston pump has many components including a piston, packings, and check valves. The piston moves up creating a vacuum to suck up the paint into a chamber, the fluid section, and down to push the paint into a high-pressure hose.

The packings create a seal to prevent pressure losses during operation. Professional airless sprayers use self-adjusting packings to prevent premature wear and the need for repairs.
