We have on board a Westfalia GEA OSD6 D.O. separator. The problem that he is working normally before but now when I joined the vessel I found that he is not flushing only with High pressure of water. So every time I have to increase pressure of water in the hydrophore till 4.5 bar that he can make ejection. Before with 3 bar he is working perfectly!!
I changed already all O-rings but still same problem.
I need your help if somebody have any idea.
Thank you in advance.

Re: Separator don't make ejection
Welcome to the Forum.
It's been over 20 years since I last laid a hand on a Westfalia, so I am sadly going to be no help.
I am sure someone will be along who has more extensive experience though!

Re: Separator don't make ejection
Weve had numerous discussion on here about separators in the past with ample trouble shootign tips, use the search feature for them.
My tip would be - check the hydrophore supply line to the separator, look for a clogged strainer / filter. They can be easily overlooked.

Re: Separator don't make ejection
The Westfalias on my last vessel were a constant source of frustration, we had simular problems however I was not directly involved. I would suggest that you have a close look at the drawings as there are some not so obvious o-rings that will cause you grief as it did for us. I wish I could be more precise however not being the hands on guy and after a couple of years the exact position of the o-ring eludes me.

Re: Separator don't make ejection
Hello
I have just joined this forum for the main reason that i see you are having trouble with your osd 6 DO purifier. We have onboard the same models and had coutless problems with them, they are now running perfect.
I see you have changed all o rings which is a start,
I reckon your next step is to clean the 2 strainers in the water operation block after this i think the problem will be fixed.
If not then make sure the pilot hole on the anular piston is completely clean?
For these purifies to shoot properly they must have at least 2 bar water pressure 1800l/h when the valve is open on the water block
Let me know how you get on?
cheers

first strainer is on the bottom of water pressure regulating valve - not marked and never mentioned in the manualdieselbike wrote:Hello

second y-strainer before solenoid block
we also had problem with rusty water supply pipe, there was pressure on local gauge but when solenoids opened there was not enough water and pressure would drop to almost 0 - had to put a hose from buffer tank to purifiers for testing - with open valve pressure is at least 2 bars like dieselbike mentioned
Alfa Laval purifiers have simple test to check quantity of water with a bucket....
