Using wort pump to fill elevated hot liquor tank

[bertdorf3]

I am about to purchase a wort pump, and I'm wondering how it might perform filling a HLT. I am figuring the pump (Chugger, most likely) will be mounted below the mash tun, and pump hot water up to the HLT The question is, do you guys experienced with pumps think it's a good idea to connect the hose (outflow) to the ball valve of the HLT, and use the head pressure to bottom fill the tank? (Approx. 4' in rise from pump outlet to ball-valve quick disconnect).

The Chugger I'm looking at says "Max Flow 7 GPM / Max Head 18.6 FT". But how does that change when pushing water up as it builds in the igloo?
The other option I thought of was putting a bulk head higher on the igloo, and another QD, and fill from the top, but that would increase the distance pumped another 2'. I assume the head of 18.6' is relative, and the higher you go the slower the flow proportionately. But how much is that effected by the volume in the tank as it increases?

Thanks for the tips!

I don't have a tiered stand but I created an elbow joint from SS for both my hot and cold water filters. Then I just hang the filter on the side if my HLT to fill.
I use a March pump to move water to my MLT.

There is no problem filling any vessel through a drain bulkhead. It doesn't matter how much volume is in the tank, only the height of the liquid matters. Flow rate does slow as head increases but you'll be fine at 5-6 feet.

Right on thanks for the info, just what I was hoping to hear!
