PD40 Series

PD40 Pneumatic Diaphragm Pump: The Preferred Choice for Durability and Efficient Feeding.

The PD40 Pneumatic Diaphragm Pump is a high-performance feeding system, making it the top choice for various automated coating applications. Here are the outstanding advantages of the PD40 Pneumatic Diaphragm Pump:

1. High Durability: The PD40 Pneumatic Diaphragm Pump boasts exceptional durability, thanks to its large-diameter diaphragm design, effectively preventing paint leakage and ensuring stable feeding.
2. Space-Saving Design: Its lightweight, compact design and excellent balance make setup and mobility more convenient. The internal frame can easily accommodate paint drums, saving workspace.
3. Ease of Maintenance: The external air-operated valve design of the PD40 Pneumatic Diaphragm Pump simplifies maintenance. Maintenance is a breeze with straightforward operation of the external air operation valve.
4. Cost Reduction: Compared to paint pressure tanks, the suction method of the PD40 Pneumatic Diaphragm Pump makes color changes more convenient. Moreover, compared to equipment from other companies, the PD40 achieves efficient delivery in a single stroke, and minimal diluent and a short cleaning time are needed, as there is no residual paint inside the diaphragm.
5. Efficient Cleaning: Equipped with the innovative paint regulator AR70, the PD40 achieves excellent cleaning performance through improvements in the connection of the liquid section and the paint path. Additionally, special processing of the inner surface of the flange plate further enhances its cleaning effectiveness.
6. Triple-Structure Suction Tube: The PD40 Pneumatic Diaphragm Pump uses a resin tube internally, providing resistance to solvents, easy cleaning, and durability.

Applications:

• Feeding paint in automated coating systems for reciprocating machines, coating robots, and more.
• Supplying paint for high-volume production coating of metal, wood, plastic products using pneumatic spray guns.
• Supplying paint for building surface coatings (such as metal paint) using pneumatic spray guns.
• Conveying pharmaceutical liquids (except strong acids and bases), and more.

Model Features:

• The design minimizes the accumulation of paint, significantly reducing the use of cleaning solvents and waste paint during color changes, contributing to VOC emission reduction.
• PD40 and PD40L feature fluororesin spraying on the flange section, enhancing cleaning compared to previous models.
• PD40L employs a small-diameter suction hose, minimizing paint and solvent waste during use and delivering excellent cleaning performance.
• PD40SW utilizes a booster valve, doubling the air pressure produced compared to the standard model, making it ideal for high-viscosity paints like water-based and high-solids coatings.
• PD40S has an all-stainless-steel paint path, ensuring corrosion resistance even with water-based coatings. When combined with a high-precision regulator, it delivers stable paint supply and uniform coating quality.
