airless painting system

DP Airless paint sprayers are available in below types, all based on the type of pump they use.

You will need to consider the material you will be applying and the extent of the job before choosing the proper type.

The airless paint sprayers are designed for big size painting jobs, because of its wide pattern atomization and high output. Some models even allow 2 painters to use it at the same time by adding an extra hose. Professional painters and contractors tend to buy these high end paint sprayers.

What kind of liquid will you be spraying? Paint sprayers with high psi (pounds per square inch), GPM (gallons per minute), and HP (horsepower) let you spray much thicker material like block fillers or elastomerics. Find a spray tip that will accomodate your type of covering best. Thin coverings are considered to be clear stains and sealers while thicker coverings are thinned latex, oil-based paints, and stains. If you are going to be working high on a ladder make sure the cord or hose is long enough to reach your desired area.

1. Electric airless paint sprayers

1.1 piston pump

1.1.1 Portable DIY pump sprayer, for example DP6388B / 6310

(At present, the item DP6388B are exported to Home Depot stores inUSA, and 6310 is a copy of Graco Magnum Project Painter Plus sprayer.

All these sprayers use universal motor with very high speed (about 15000rpm).  1/2hp motor, max.200bar pressure, and 1L/min capacity.

These sprayers are only for DIY users, because it’s not suitable for everyday using.

But it’s ideal for the family painter who spray only once or twice per month.

You can use it for spray both enamel or latex (not strong latex), both oil-based and water-based.

And you can connect it with paint roller for fast rolling jobs, if you don’t want to move your furniture or table, just cover it with newspaper.

1.1.2 Professional airless paint sprayers, for example  DP6495 / 6695 / 6795 / 6389-440i / 6640i / 6740i

All these machines use PMDC (Permanent MagnetDC) motor with low speed, but very strong power.

They have different motor power and range of spraying output capacity, from 2L/min to 3L/min

The items 6495 / 6695 / 6795 are similar to Graco Ultra Max II 495 / 695 / 795

And the sprayers DP6389-440i / 6640i / 6740i are similar to Titan 440i / 640i / 740i

Many parts are compatible with original Graco or Titan machines.

And we have brushless motor for these items also. The high performance brushless motor will supply you the 100% guaranteed strong power and tight pressure deadband, always ensure you the consistent spray pressure with low pulse.

1.1.3 Semi-professional airless painting equipments, like DP6386 / 6385 / 6387

These items are designed for small contractors. The quality is good, but you need some more maintenance to these models, because the parts is not top quality for last longest lifetime.

1.2 diaphragm pump

We supply the highest quality diaphragm pump sprayer inChina.

There’re many users in different countries which though the diaphragm pump has many problem, not good quality. But I’d like to remind you the diaphragm pump sprayers have many advantage, like low noise, easy maintenance, fast repairing. And the induction motor doesn’t have any spark. And specially it can be used for rough paint even though it contains small grains inside.

The diaphragm pump only have 3 easily worn parts, that’s Diaphragm / Inlet Valve / Outlet Valve. And you can change all these parts in 5 minutes by wrench manually. It’s much easier than piston pump.

And the diaphragm pump could generate higher pressure (max.250bar) than others.

But the disadvantage is the diaphragm pump system doesn’t support strong (high viscosity) paint. If you want to spray heavy paint, you’d better chose piston pump.

 2.  Pneumatic airless paint sprayers

The pneumatic airless paint sprayers are for industrial / commercial / factory using. not for DIY or small contractors.

These pneumatic airless sprayers need air compressor to power the machine, the compressed air (5-8bar) will generate the high pressure for heavy coating spraying jobs.

If the machine’s pressure ratio is 30:1, then it will generate maximum 30*8=240bar pressure

if it’s 60:1, then the max pressure will be 60*8=480bar

The different size of air motor / cylinder, and size of fluid pump, will generate different range of pressure ratio for your choice.

The most popular models will be K151 / K301 / K451 for furniture, shipyard epoxy, factory, steel metal finishing etc.

and DP6370 / 6391 are designed for toughest jobs, heaviest painting, anti-corrosive, water-proofing, fire-proofing, zinc-rich, shipyard etc. They have bigger size air motor, and bigger size fluid pump, and of course generate bigger output volume per minute.

3. Petrol / Gasoline airless painting equipment

Yes, sometimes there’s no electricity at the jobsite, no matter it’s interior or exterior, the gasoline sprayer will be your only choice.

we equip our machines with HONDA GX 160 engine, the proven quality will always reliable and meet your request.

we have different models which attach with Diaphragm pump (DP6845) or Piston Pump (DP3400 / 3900)

And also we put them onto the cart for line-striping / road line marking purpose, with the same engine / same fluid pump.
