Hi John

 

Sunpumps makes a really good one. 

 

Here is a ebay link showing many of the new probably Chinese (not saying they are bad) but they are way less expensive than the US versions. 

 

https://www.ebay.com/i/293234996712?chn=ps

 

I expect if you shop AliExpress you’ll find these exact items. 

 

Cheers

Jay

Yes they are for positive displacement pumps – and the question was where can you find them – who makes them…??

 

Thanks,      John

Probably an RV water pump? And an LCB should work. Who makes a good LCB for this Jay?

Hi john,

 

I'm not sure which pumps you are talking about. Are these positive displacement, and if so then an LCB is what you need.

Where can you find some small maximisers/optimisers for a solar-only pump.   This would be for a surface pump like the Flojet 11, 12 or 17 litre/min pumps.  They tend to keep the pump operating when a cloud goes over or in low-light conditions.    I think they are available for the 9325 but its probably over-kill for the Flojets.

Cheers for suggestions – John Veix,    N.Z.
