Pumps for brewing: market research

[Hop Bomb]

I bought the hop blocker in HBW but brought it back. I had the tap already fitted on my kettle & retro fitting this would have been very difficult. Grand on the blichmann pots Id say as the have that swish screw off dip tube. In the end I got a stainless hop spider.

I think spider is the way to go but easy to make one if these. I'm guess for someone with no access to stainless it could be made by drilling holes in plastic pipe. Small ones at bottom and bigger on top. Then cut same size pipe down the side and slip it over drilled piece to cover small holes then pull it up allowing small holes to do the work. Nice little diy project for someone

If you really want to throttle down the flow from a pump you use a diverter valve.

Full open: All liquid goes to where you want it

Fully closed the liquid is recirculated to where it came from.

In between: Whatever ratio you want

This is the priciple used in High Pressure Hydraulic pumping circuits and the like.

It can just be as simple as a pressure relief valve that "blows off" to the source reservoir

Can a speed control valve be fitted like a dimmer switch.

Saw this on JBK. I think it's what Will is describing?

agree will, a simple 10 euro 20 litre a minute washing machine pump has this built in as has my salamander WHP pump
However if people arnt aware then fried pump is possible through overheating, we cant just restrict the flow, thats like driving ur car with the brakes on
