    Why is my Lukas Water Pump device moving slowly?
    • J
      Jeremy NortonAug 16, 2025
      If the connected device with your Lukas Water Pump isn't moving, is moving slowly, or is moving intermittently, it could be due to several reasons. First, check if the fluid level in the hydraulic tank is too low and add hydraulic fluid up to the maximum fill level. Also, ensure the discharge valve is closed. Inspect the hose line for proper connection and any damage, reconnecting if necessary. The load on the device might be too high, so consider using a different device. If there's air in the hydraulic system, bleed the system. If none of these steps work, there may be a defect on the device, so heed the specifications of the operating instructions of the device.

    Why is fluid leaking from my Lukas Water Pump's hydraulic fluid tank?
    • V
      vgrantAug 19, 2025
      If you notice fluid leaking from the hydraulic fluid tank of your Lukas Water Pump, especially at the refill tap, it could be due to the maximum fill quantity of the tank being exceeded because of the return flow of the hydraulic fluid from the device. To fix this, reduce the hydraulic fluid down to the maximum fill level. Also, check the seals for defects and replace them if necessary.

      lawrence72Aug 23, 2025
      If your Lukas Water Pump's connected device moves but doesn't hold pressure or deliver the specified performance, check the hose line for proper connection and any damage, reconnecting if necessary. If there is a leaking seal, locate the leak and have the hydraulic pump serviced by an authorised dealer, by personnel specially trained or by LUKAS directly. For internal leakage of the pump, have the hand pump serviced by an authorised dealer, by personnel specially trained or by LUKAS directly.

    What to do if Lukas Water Pump connected device doesn't reach limit position?
    • N
      Nicole AdkinsAug 26, 2025
      If your Lukas Water Pump's connected device isn't reaching its limit position, it could be due to a low fluid level in the hydraulic tank. Add hydraulic fluid up to the maximum fill level, making sure to move the device back to its base position before adding fluid. It could also be that the usable hydraulic fluid quantity of the pump is insufficient, so use a different device with a usable quantity below the pump's maximum usable quantity.

    Why Lukas Water Pump connected rescue device doesn't achieve performance data?
    • C
      cfischerAug 28, 2025
      If your Lukas Water Pump's connected rescue device is not achieving its power-related performance data, it could be because the maximum permissible operating pressure of the pump is not being reached. To resolve this, replace the pressure control valve or have it recalibrated by an authorized dealer or directly by LUKAS.

    Why is the hydraulic fluid in my Lukas Water Pump milky?
    • J
      jmartinAug 31, 2025
      If the hydraulic fluid in your Lukas Water Pump has a milky cloudiness, it indicates water or condensation water is in the system. You should perform a hydraulic fluid change immediately.

    Why Lukas Water Pump device doesn't move back to the starting position?
    • J
      jamessimonSep 3, 2025
      If your Lukas Water Pump's device isn't moving back to the starting position, moves incompletely, or moves more slowly than normal, it could be due to several reasons. Ensure the discharge valve is open. If the fluid level in the hydraulic tank is too high, reduce the hydraulic fluid down to the maximum fill level. Check all couplings and retighten them if they are loose. If there is enclosed air in the system, bleed the pump. If the line length is too long, use shorter lines. Use hydraulic fluid with a different, more suitable viscosity. If none of these steps work, there may be a defect on the device, so heed the specifications of the operating instructions of the device.

    Why hose lines cannot be coupled in quick-disconnect Lukas Water Pump?
    • J
      Jill HarveySep 6, 2025
      If you have a quick-disconnect coupling system and the hose lines cannot be coupled to your Lukas Water Pump, it could be because the system is under pressure. Open the discharge valve and bleed the device. If the coupling is defective, it should be replaced immediately.
