Re: HFS-6 Inconcistent Injection
 

Another update,

I have pulled apart the pump, haven't found any signs of corrosion in the pump, bearings etc look fine, spins freely by hand. The diaphragm looked really clean as well.

I am not sure of the anti surge unit on the outlet of the pump, whether it could have blockages etc. Is this unit necessary, i notice the later pumps don't have it.
Looks like ill need to wire in a pressure gauge and see what pressure is coming from the pump.

Is there a way to test the hall affect sensor on the printed circuit board?

Is there a minimum flow that the sensor will only work on. I presume that if i get 260cc a minute, that the sensor should read this, as with a smaller jet installed 260cc/min is achievable.

What pin on the gauge is the flow sensor trigger?

Regards

the flow sensor may require cleaning. There is a filter between the tank and pump.

I have a full hfs6 that I’m parting out. I bought it 5 years ago or longer and never installed it. When I tried to use it this year the Ethernet connectors on the circuit board are loose or something and it wouldn’t function properly. Long story short if you need any parts for the hfs6 I have a full kit to part out with.
