Watermaker

Onze watermaker is een Livol D30, tweedehands aangeschaft via marktplaats.nl. Hij is nagekeken door de leverancier (shipshop.de) en in orde bevonden. Het apparaat is ingebouwd door Sailtec. We hebben een plaatsje voor de watermaker gevonden boven de extra dieseltank in de stuurboord opslag. Dat wordt langzamerhand een complete technische ruimte met de dieseltank, dieselfilters en kranen, watermaker met pomp en filters, vuilwatertank en walstroom/laadautomaat. De Livol is overigens niet meer verkrijbaar. De fabrikant is enkele jaren geleden overgenomen door het franse SLCE. Zij produceren de Aquabase watermakers. In Nederland weet Rob Wink alles van watermakers. Hij levert de Schenker watermaker, maar ook filters en spoelvloeistof voor alle watermakers. Dit plaatje van het werkingsprincipe komt uit een animatie op de website van Schenker (let op het italiaanse Engels!)watermaker principe

Watermaker troubleshooting:

These hints and tips were provided to us by Shipshop.de and proved very helpful:

  • Please check the following:
  • 1. Pump
    The raw water pump must produce around 300L/h with 5-6bar pressure. You
    should not be able to stop the water flowing off the hose by pressing
    your thumb on the outlet of the hose. Please change pump head against a
    new one if in doubt. I have tested with the old one but that pump heads
    are very sensitive and can worn out in seconds if not bleeded with water.
  • 2. Power
    For working propper it needs at least >12.5V on the pump connectors and
    draws around 8-12 Amps depending on the installation.
  • 3. Flow and Hoses
    Please check very thoroughly all the hoses and connectors – are they
    free without hard bendings ? All valves ok and allowing free flow ?
    Seewater Intake clean, Prefilters clean ?
    Then, outlets all free ? Seawater and production (drinkiing) water ?
    Please note when the pump is not situated on or better under the
    waterline it cannot work very good, it is a pressure pump not a sucking
    one. Also very long hoses and a >50cm difference in height between pump
    and watermaker and watermaker and outlets will affect the working (but
    not down to 50%).
  • 4. Air
    Most tricky thing, have heard often of that causing problems. The
    complete system must be free of air bubbles. If the bleeding procedure
    does not help and you will hear streaming noises all the time the
    hydraulic system removes you have to lift the watermaker on the left
    side (opposite the manometre) up to more then 45° while working and redo
    the bleeding procedure. 

    Hint: When the watermaker is running a while and you then open the
    bleeding valve – does it then give some air bubbles out of the waste
    water outlet ? This is a sign that the hydraulic system is not free of air.

  • 5. Pressures
    With drinking water the pressure is around 15bar, with sea water in the
    Med it should be around 40bar. More then 50bar needs a cleaning cycle
    with the membarne cleaning solution.
