Spray gun with pump

"Spray gun with pump installation" is a system that uses a pump to transfer material from a storage tank to the spray gun. This system is more modern than the "pressure-port installation" spray gun. This equipment system is used a lot in the large-scale finishing processes, such as the manufacture of furniture, doors, panels, or other wood products in factories. The "pump-system spraying equipment" is also found in many finishing shops due to its great benefits.

Like a pressure-pot spray gun, the finishing material is stored in a separate tank and flows to a separate spray gun. It means that the spray gun can maneuver in any direction, with free and flexible movement. The difference is that the material is flowed with a pump that gives many advantages. The material flowing is more stable, and material replacement is more simple. The equipment cleaning can be easily done by unplugging the material hose from the old tank and inserting it into the new material tank. The equipment cleaning is done by taking off the hose from the old material and inserting it into the thinner tank, then running the spray gun until the pump, entire hose, and spray gun are filled with thinner and clean. Cleaning and replacing the material can be done quickly without the hassle of opening and closing the storage tank, which is time-consuming.

In a big wood finishing factory, all finishing materials can be centralized in one location that is called the mixing room. In the mixing room, the finishing materials are stored, mixed, and controlled. The materials are pumped to each of its spray guns to be applied according to the finishing process in the finishing room through a piping system.

Types of pumps

• Diaphragm pump

Diaphragm pump is a low-pressure pump commonly used to deliver finishing materials over short distances. The finishing material is stored in a single tank located near the spray area; the hose is inserted into the liquid to be pumped and sprayed by the spray gun. The diaphragm pump can only deliver material at low pressure; therefore, it can only be used with air spray or HVLP spray guns, and the equipment needs to be located in the finishing area. 

• Piston pump

Piston pump is a higher-pressure pump. This pump can provide the high-pressure material that is required for airless or air-assisted spray guns. This pump is also used to deliver material over long distances from the mixing room to the finishing room in a centralized system.

Pump installation

The advantages of spray gun with pump installation

• High-flexibility of spray gun movement

Like a pressure pot system, the spray gun is installed separately from the tank, allowing for more freedom and flexibility in its movement. This equipment is very helpful for spraying large and complex objects or big volume production. The gun is lightweight and easy to be handled, finally reducing the operator's fatigue. 

• More consistent results

The use of a pump creates a more stable material flow, ultimately resulting in more consistent coating results. With proper air regulation, the spray process will also be more efficient and reduce overspray.

• Can handle the high-viscosity materials

The pump can deliver the high-viscosity materials to the spray gun, and they can be applied in the spray gun. The materials can be mixed and sprayed in a high solids content, and then you can form a higher film build in fewer applications.

• Available for all types spray gun 

The high-pressure pump is available to supply the airless and air-assisted spray guns that need high pressure. While the air spray gun and HVLP gun can use the diaphragm pump, which is simpler and cheaper. 

• Increased productivity

This equipment is very useful for large-scale finishing application processes. Cleaning the equipment can be done more quickly and conveniently, saving time, energy, and thinner. Likewise, replacing materials can also be done more quickly and easily. With proper settings, this equipment will reduce the operator's physical job and fatigue. 

Things to consider when using the pumps 

• Consider the work volume and types

The pump is an excellent tool to handle the large-scale finishing jobs. However, you will need money to buy and install it. Learn and understand the finishing process you are going to do. Do a simple calculation to see your job volume. Then you can choose the best-suited pump according to your needs. There are many types and variants of pumps provided by the equipment supplier, so you can choose the most suitable equipment according to your job. 

• Proper installation

To effectively flow materials, a good circulation and piping system is required. The pump system to flow the materials from a tank to its spray gun in the finishing room is simple thing. But when you build the centralized system from the mixing room to the finishing room, it is complex and requires detailed and precise settings. Make sure you properly install and set up your pump, piping, and spraying equipment to make sure they work well.

• Maintenance system

The pump and its installation require proper maintenance to work properly and last longer. Make sure you know how to take care of and maintain this equipment.
