Optimized Beckett

[salt lick]

Waylander,
Hard to say if the cone makes a difference. someone on this thread pointed out that as the volume of air sucked in the Beckett goes up the flow of the water decreases. I had not realized this before. explains why its hard to tune small or short skimmers, you have to iterate the gate valve and the air valve. so less back pressure should create more suction and more water flow: which means water height in the neck might not change! Need to measure water height and cc/min air to determine effects. It didn't hurt performance.

salt lick good way to ajust the beckett is with a air gage it helps wth the performance of the skimmer.

Where can we pick up the air gauge?

 

[RGibson]

Dwyer -RMB 53 D air gage and you can buy it from Dwyer. com

Ok, I have finally read this entire string. Now a question based on a thought I had. Has anyone drilled their holes at angle to the flow or has everyone drilled straight in? I was thinking maybe if the holes were at say a 45 degree angle to the flow if it might increase airflow?

 

[RGibson]

How about having 3 air intake holes in the beckett holder to let the air come in from all sides to the beckett and you will need 3 air lines the same size to tie into the air valve for air control .The 3 air lines will need the same length.

I think as long as you have a gap around the beckett head, the one airline would do fine.

The angled intake might help slightly, but the opening would still have to be at the top of the original holes. So when you start the hole, it will need to be higher up to compensate for the angle.

Does anyone have plans for a Beckett Skimmer? I have searched, and found lots of different plans, so I guess I would like to see plans from a skimmer that someone has built and will recommend. Please help me, as I really NEED to replace my sea clown and have not much money to do it.

I tried these mods on my becketts and saw my performanc drop drastically. I run mine with a pcx-100

 

[MightyMike3434]

Rod, could you be specific regarding what "dropped" exactly? and which of the mods you tried? Thanks

 

[mushumatt]

Hey guys im just reading this and im new to the beckett world with my PM bullet 3. After seeing salt licks picture basically a beckett injector is alot like a basic jet engine

 

[Bax]

I'd like to hear how the mod has performed for those who have done it over the last few months ... still worth the effort and cost of the Becketts?

 

[einsteins]

It seems to work best with pumps that are not pressure rated.

I saw an increase when I was using it with a mag18 driving my skimmer.
I now have a Sequence Wahoo and it does not make as much difference

Any updates?

Curious, but not about to read the entire thread.....

I have a beckett skimmer runnning off of a Mag 12, so I have tried both the standard & modded beckett designs with some differences.

One question:

Has anyone tried to run the beckett WITHOUT the innermost piece ( the cross piece with the ball on the end )???

Just remove that piece and let me know what happens please.....

BUMP - !!

all this talk about optimizing a beckett......

Has anyone tried using it without the insert thingy with the ball??

I stared at my beckett, and contemplated the venturi concept.
I dont believe that the insert helps with changing flow to vacuum. ( the whole venturi concept ).

So I took out the insert, and my skimmer runs better than ever.

Anyone else willing to test?

how can that be? The ball is what makes the volume change. I don't see how it can work without the ball.

Can you take a pic of the beckett.

"how can that be? The ball is what makes the volume change. I don't see how it can work without the ball."

Here is a pic of a beckett ( not mine ) from this link:
http://www.rl180reef.com/pages/filtration/beckett.htm

The piece that I removed is the insert with the ball at the end.

Here's my thinking:

The whole concept of a venturi is to force water through a restriction. A restriction is a reduction in cross-sectional area that the water is flowing through. The change in area causes a change in flow velocity which in turn causes a vacuum that pulls in air.

If you examine one half of the beckett with the ball insert in it, you will see that the cross-sectional are of the region that the water flows through is essentially constant as the water passes around the ball and out the other end. This is also the region that the air holes are in. The beckett without the insert has a much larger change in cross sectional area right where the air holes are.

Another difference I see is that the beckett housing is completely empty of water. When running with the insert in, water leaks out through the seams in the beckett. The water level in the housing then fills up to the air holes where the water is sucked back into the beckett.

Now that I run without the insert, the water doesnt squirt out, and the vacuum created is obviously sucking IN through the seams near the bottom, and all the water was sucked out.

Stugray can you tell me about your beckett holder you have and how the air comes in top or side of the holder?
