Positioning the pump head?

Post by HopHeadScott » Fri Sep 06, 2013 5:43 pm

1: Instructions say inlet faces down

2: Phone support says inlet faces up

3: a post here says inlet faces down

4: Phone support #2 asks around, comes back and says inlet faces sideways

So whats the right answer?? or is there a right answer? Ive used the flat system twice with the inlet facing up and get occasional cavitation

What pump?
I see now you are talking brew sculpture.
I use a March pump w/o a sculpture. The inlet is sideways when I place it on the ground to pump.

I am a mechanical engineer working with centrifugal pumps my entire career so trust me on this.

The pump works best with the inlet facing down (6:00 position). This merely helps naturally purge the air out of the system on startup. Otherwise, you have to mess around with a purge valve on the discharge. Here's mine.

Yepp - just to add to the confirmation, inlet points down - or a slight distinction is that the outlet should point up to give the air a place to easily travel (I have a center inlet pump as well and point the outlet up).

Inlet pointing down.....

But to also add here, your pump needs to be below all of the kettles that will be sending fluids to your pump. This will allow gravity to push your wort through the pump head and up through your Outlet which by default is pointing Up.
