Pneumatic Diaphragm Pump PD40 Series

PD40/L/S/SW

  • Four-wheeled vehicles/parts
  • Motorcycle vehicles/Parts
  • Aircraft / Aircraft parts
  • Electronic equipment
  • Construction machinery
  • Reduce paint usage
  • Increase productivity

Easy to clean and remarkable stability.

FEATURE

  • Diaphragm pump prevents paint leaks due to packing wear, enabling highly-stable coating.

 

  • Paint retention parts have been greatly reduced for easy solvent cleaning during color change, while paint waste and

    VOC emissions are significantly reduced.

  • The flange is coated with fluorine resin, making it even easier to clean than previous models.(PD40・40L)

 

  • A small bore suction hose allows you to use paint and solvent without waste, and makes it remarkably easy to clean.

    (PD40L)

  • A pressure increase valve produces twice as much air pressure as the standard type, making it ideal for high-viscosity

    paints such as water-based and hybrid paints.(PD40SW)

  • The paint path is constructed entirely of stainless steel, preventing corrosion with water-based paints, etc.(PD40S)

Introduction:Facing challenges with aging equipment—such as inconsistent coating quality, low transfer efficiency, increased paint consumption due to touch-up coating, and a deteriorating working environment—the company implemented a new coating system.

Benefits
1. A high-transfer-efficiency automatic coating gun reduced paint consumption by 30% and improved the defect rate from 15% to nearly zero.
2. Touch-up coating was eliminated, reducing operator workload and improving the working environment by reducing paint mist.

Introduction:To resolve quality variation, booth contamination, complex color changes, and low productivity caused by hand spray coating, the company upgraded to an automated coating system.

Benefits
1. By using an automatic spray gun with an angled compact head and optimized coating robot paths, teaching was simplified,which reduced overspray, lowered paint consumption, and improved productivity.
2. The introduction of a color change valve enabled one-touch color switching, eliminating complicated color change operations.
