The linears are further down. They don't have the PSI you need.

At your elevation, I would stick with the BLDC motor, whichever one is the most suitable for your requirements. The 75R would work if they really offer it in BLDC for a single purchase.

If anyone is interested, there is a new 230Vac 75R on ebay for $280.00 or best offer. http://www.ebay.com/itm/GAST-75R645-P101...P-/291408932091

I was going to have a friend of mine buy it for me, but really don't need one at the moment.

EDIT: I've been looking all morning, and am not coming up with an off the shelf solution in BLDC for your application. Not even in multiple smaller pumps.

I'm also finding that your ambient air temperature in the winter may be too cold for these to operate without a heat source.
