I'm selling an IWAKI metering Pump Model EHB10R1-VC
Specs for this machine and the definitions of the various letters in the model number are on this PDF document: http://www.walchem.com/nav/CMImage.a...=EHBCbroch.pdf
Max output: 0.6 gallons per hour/38 ml per minute against a maximum pressure of 150 psi
Output per stroke: MIN 0.05 ml / MAX 0.11 ml
There are several uses for this pump in our hobby.
1) can be used with a Kalk reactor to slowly drip kalk solution at precise and steady rate eg.

2) or it can be used with a calcium reactor for precise effluent rates
3) precise dosing of your additives (Zeovit/Reefresh/Amino acids etc)
I'm selling because I have an extra one that I will no longer need.
