Rant warning.
Manufacturers need to get their act together. Even among "energy efficient" lines, efficiency is confusing. As a technical guy that loves to over-research things, pump specs are absurdly confusing and without reason.
For example, based on reading this forum, if I asked, "what is the ENERGY EFFICIENT line of single-speed Hayward pumps", I'd probably get "Tristar" as an answer, along with a few recommendations to use Ecostar or some other 2-speed pump.
"Great!", someone looking for an efficient pump says. "All I have to do is get a Tristar! (or Pentair Whisperflo) of X horsepower!"
Not so simple though. Look at these:

http://www.hayward-pool.com/prd/In-Grou ... 0828_I.htm
Same for Pentair's "energy efficient" Whisperflo line. (Amazon Whisperflo page which says, "Standard and energy-efficient square flange motors available").
I suspect the Tristar/Whisperflo pump housing itself is better flow-optimized and that the motor, technically separate from the rest of the pump, is independently available with different efficiency ratings, but seriously -- how the heck is anyone supposed to figure this out? Even coming here and reading over two dozen TFP posts singing the praises of energy efficient pumps, this was never mentioned once. TFP is probably the densest concentration of pool expertise on the internet. The only reason I looked into it is to figure out the difference between identical product pages on Amazon.
Pardon my arrogance, but here's a clue for Pentair and Hayward: Sell the minimum number of pump lines.

- Same series -- the energy efficient "Tristar" series[/*:m:6531annv]
- Same HP[/*:m:6531annv]
- Completely different specs (I've read Pool Pump Basics)[/*:m:6531annv]
- Efficiency: "Standard" for one (???), "Energy efficient" for the other[/*:m:6531annv]
- Different price on Amazon[/*:m:6531annv]

- Variable speed, high-efficiency, expensive (EcoStar, IntelliFlo)[/*:m:6531annv]
- 2-speed, low-efficiency, cheap (e.g. SuperPump 2, Superflo 2)[/*:m:6531annv]
- 2-speed, high-efficiency, mid-cost (e.g. Tristar 2/Whisperflo 2)[/*:m:6531annv]
- 1-speed, low efficiency, cheap (SuperPump, SuperFlo)[/*:m:6531annv]
- 1-speed, high efficiency, mid-cost (Tristar/Whisperflo)[/*:m:6531annv][/list
:6531annv]
- Any necessary variations (e.g. waterfall pumps) must have an obviously different, clear, totally unambiguous, distinct model name which requires no analysis of the bullet points or specs to know that there is a physical difference.[/*:m:6531annv]
If you don't agree, then go find a knowledgeable but non-expert friend and tell me that they can look at this page (which doesn't even list the standard/high efficiency options this email is about!) and have any idea what pump to get.
Any mature industry moves towards simplification of product lines through ad-hoc agreements between manufacturers. This industry is run like a bunch of start-ups by engineers dispassionate to the importance of marketing and product identity to "clueless consumers".
The same applies to all other pool equipment. Go to Hayward's pool filter page. Useless. (Wow, these are all great! Which do I pick!?) It isn't hard to write 2 pros and 2 cons for each technology so that someone visiting the page may begin to make a reasonable decision without spending weeks researching the finer points of computational fluid dynamics. Fix it.
