Marine Color 3-Part Dosing System w/Modified Pumps

 

The Marine Color Dosing System is now available at OceanboxDesigns.com.

 

This is a great dosing system, however one major flaw lies within the pump heads. While the pump is operating, the tubing is allowed to move outward perpendicularly to the spindle due to the centrifugal force and introduce air bubble into the tubing. When this happen, it will throw the dosing volume out of balance and become highly inaccurate!

 

I have found a way to fix this issue and I'm offering the modded pump heads for anyone who purchased my system. The modified pump heads included an o-ring retainer (1 per head) to keep the tubing from sliding outward and air tight. This will also keep the tubing from rubbing against the outer casing and reduce pre-mature wear.

• Increase Dosing Accuracy.
• Eliminate Air Bubble Inside Tubing.
• Reduce Pre-Mature Wear Of Tubing.

Crazy. I never had a single issue with my Marine color several years ago.

Crazy. I never had a single issue with my Marine color several years ago.

I've tested several units, they're all the same, the pumps produce a lot of vibration and the mounting base aren't fully secured and vibration will cause the head to come apart and allowing the tubing to slide outward. Another mod I did (wasn't mentioned above) was securing the mounting base (not the pump housing) with superglue, this prevent it from coming loose and enhance the performance greatly. Note that you can still replace the pump head if needed since only the mounting plate is glued down and not the pump housing itself.

 

I only want to improve its performance because I didn't want to sell something that i know could be problematic for my customers, had I not known I would have left it alone but since I experienced the issue myself and I have to fix it. Plus I didn't add any extra cost for the extra work so it's win win for everyone
