Servicing airless pumps, used for spraying paints, coatings and other materials, is important to ensure that the equipment functions properly and that high-quality results are achieved. Here are some key steps for the service and maintenance of airless pumps:

  1. User’s Manual: Always start with the user manual provided by the manufacturer. This document contains essential information on operation, maintenance and troubleshooting specific to your airless pump model.
  2. Visual inspection: Before each use, carry out a visual inspection of the entire equipment. Check for visible damage, leaks or worn components.
  3. Cleaning: After each use, thoroughly clean the pump, feed tube and nozzle. The accumulation of residual material can obstruct the flow and impair the quality of the spray.
  4. Nozzle replacement: airless nozzles can wear out over time and affect spray quality. Check the airless nozzle for wear and replace it if necessary. The frequency of replacement will depend on the intensity of use.
  5. Pressure check: Make sure the airless pump is delivering the correct pressure. Check and adjust the pressure according to the specifications of the material you are spraying and the manufacturer’s instructions.
  6. Filter check: Check and clean or replace the filters, including the suction filter and nozzle filter, according to the manufacturer’s instructions. Removed filters should be thoroughly cleaned or replaced with new ones.
  7. Lubrication: Check whether your airless pump requires regular lubrication, such as lubrication of seals or pistons. Use the oils or lubricants recommended by the manufacturer.
  8. Check connections: Check all connections and joints for leaks or looseness. Make sure that all connections are secure.
  9. Periodic maintenance: In addition to regular cleaning and lubrication, schedule regular maintenance in accordance with the manufacturer’s instructions. This may include overhauling seals, replacing wear parts or checking overall performance.
  10. Training: Ensure that operators using the airless pump are properly trained in the use and maintenance of the equipment. This will help prevent accidental damage and extend the life of the equipment.
  11. Troubleshooting: familiarise operators with basic troubleshooting procedures so that they can deal with common issues appropriately and safely.
  12. Professional assistance: If problems or defects occur that cannot be solved in-house, contact a WIT technician who will promptly provide professional assistance, on request also on site or at the workplace.

Following these guidelines for the maintenance and servicing of airless pumps will help ensure that the equipment functions properly and that optimal results are achieved in spraying applications.
