Progressive distributor: Diagnosis & maintenance (practical guide)

DropsA Germany

Progressive distributor diagnosis and maintenance

Progressive systems deliver defined quantities per cycle. The advantage: clear diagnosis via stroke sensor/limit switch. This is how you proceed in the event of malfunctions and maintenance.

Fast diagnosis (workflow)

  • Visually: Leakage, loose fittings, damage
  • Medium: Viscosity/NLGI suitable Air in the system
  • Sensor technology: Stroke sensor LED/signal, wiring, counting in HMI
  • Function: Solve and encourage departures at random

Typical causes & measures

  • Blockage at the distributor: Clean, replace dosing element
  • Air in the system: Bleed, check refill process
  • Missing impulses: Sensor adjustment/defect, cable break
  • Uneven delivery: Adjust quantity/interval, check cable routing

Maintenance checklist

  • Weekly: visual inspection, messages in the HMI
  • Monthly: pulse counting/trend, random quantity check
  • As required: cleaning, filter/lubricant change according to plan
