Help with pumps

[maltbarleyhops]

recently purchased a single tier brutus. love it. but.......the pumps on it(march pumps) wont prime very easy. I was thinking my lines may be too long. but asi have been away from brewing for a few years I started reading some old notes. do I need a grant vessel for these pumps?

if so, I need some serious advice,want to brew again this weekend.

thanks, and its good to be back!

I find it works well to close the exit valve on the pump before opening the valve on the kettle. Let all of the air bubble out of the input tubing before you open the pump valve, and the wort should push right through the pump head.

What is the style of pump head? If they are the inline style then the inlet needs to be on the bottom and the outlet on the top. Do not restrict the input at all.

The pumps could be well loved. If this is the case the teflon bushings inside the pumps could be worn out and causing issues. Might be something to look into.

Post a picture of your brew rig showing the pump location and orientation...

Cheers!

Agreed with the above. Post a pic. Ideally you want the inlet at the 0600 position, and have your regulating valve on the output side (1200).

They don't prime at all... they need to be placed well below the vessel with no loops or low points in the hose. A bleeder valve to release trapped air helps a lot.

rig is similar to the above pic. but my inlet/outlets are at 3 and nine. will turn them and test.

thanks!

maltbarleyhops, if your inlet is at the 3 O'clock position and the outlet is at 9 then you need to flip the pump head 180* and it will help greatly...
check out this thread i posted a while back on orientation.
