Barrel Transfer Pump for the Paint, Lacquer, and Coatings Industry

Production of paints and lacquers involves a precise, step-by-step process where each stage impacts final product quality. Gloss, adhesion and viscosity are critical factors. However, overall quality hinges on efficient pumping, filling and dispensing. Equipment deficiencies at this stage can lead to inconsistency, therefore, undermining previous production efforts. Flux Pumps UK provides a barrel transfer pump range specifically engineered to handle the unique challenges of paints, lacquers and coatings. Our range, including pumps such as the class-leading F 424 and Viscopower models, ensures smooth and efficient transfer of even the most viscous and sensitive liquids.

For transferring paints and coatings, selecting a pump that guarantees safety, precision and durability is essential. Therefore, Flux barrel transfer pumps stand out thanks to their robust design, chemical resistance and ease of operation. As a result, here’s why they’re the top choice in the coatings industry: 

• Designed for viscous liquids: Our Viscopower pump handles thick, heavy liquids without compromising on flow rate or precision. Additionally, our pumps are suitable for various paints, lacquers, adhesives and coatings, and we stock stainless steel pumps for handling solvents, thinners and degreasing agents. 
• Chemical-resistant construction: Built using stainless steel 316 and high quality fluoropolymers, our pumps withstand exposure to all solvents and cleaning chemicals. 
• ATEX certification: Models such as our F 430 Ex and F 424 Ex are ATEX-certified and safe for transferring flammable liquids with low flashpoints, when used with our F 416 Ex and F 460 Ex motors. Their design, encompassing zone separation and earth bonding, reduces the risk of static electricity buildup. 
• Easy cleaning: F 430 is easy to disassemble for quick cleaning and maintenance, consequently preventing cross-contamination. 

When selecting a drum pump for paints, lacquers and coatings, it’s essential to consider the viscosity, chemical composition and temperature of the material you're transferring. Flux Pumps offers a range of drum pumps that efficiently handle various paints and lacquers, including both low and high-viscosity liquids. Our pumps are constructed from materials such as stainless steel 316, PTFE and FFKM, guaranteeing compatibility with many different chemicals.

We can provide pump selection guidance based on the specific characteristics of your paint or lacquer. Therefore, if you are unsure, we recommend contacting our expert team to help you choose the best solution. 

Maintaining and cleaning your drum pump is critical to minimise contamination risk, maintain efficiency and extend service life, especially when dealing with paints and coatings that can dry or harden inside the pump. Here are some simple steps for proper maintenance and cleaning: 

For the best results, refer to specific cleaning and maintenance instructions, as each model may have unique requirements.  

The VISCOPOWER is ideal for filling viscous materials such as emulsion paint. Firstly, it’s progressive cavity design provides smooth, laminar flow without turbulence, aeration or pulsation. 

Key features: 

• Handles high-viscosity materials with ease. 
• Provides high discharge pressures up to 15 Bar and flow rates up to 50 LPM. 
• Easy to clean, with few moving parts. 
• Compressed air or electric motors available. 
• Operates at low noise levels for a comfortable workplace. 

The pump sits in the production vessel. Once turned on, the media flows into the pump inlet chamber, before being displaced upwards by the rotation of the rotor. The rotor turns inside a fixed stator, made of PTFE or NBR material. The spiral-shaped opposing geometries of the rotor and stator opens and closes chambers, through which the material is moved as the rotor continues to turn.

Thus the paint is pushed up into the pump tube, before being discharged via the side outlet port, through a flexible hose and into buckets placed on a floor scale. The pump is manually stopped once the desired weight is reached. Custom accessories are available to suit specific needs—contact Flux Pumps for tailored solutions. 

The RFM 25 air-operated diaphragm pump is ideal for transferring printing ink from drums, barrels and IBC’s into processing systems. 

Air-operated diaphragm pumps comprise a rigid outer body in plastic or metallic material, with two internally mounted diaphragm membranes that are joined by a shared shaft. The diaphragms separate the compressed air and liquid “sides” of the pump. Subsequently, a shuttle valve diverts compressed air to the rear of each diaphragm in turn.   

As the shaft shuttles back and forth, liquid is drawn in and pushed out of each fluid chamber. Each chamber has in inlet check valve (typically a ball or flap) and a discharge check valve. The check valves open and close in turn as the shaft moves back and forth. Thus, fluid moves in and out of each pump chamber in turn. 

The pump draws paint directly into suction pipework and delivery flow rate can be varied by increasing or decreasing air flow to the pump, or by adjusting a valve in the discharge line. Additionally, dampers are available to reduce pulsation and smooth out the flow rate. Stroke counters can be used to measure the volume that has been dispensed.
