We use the Pentair Intelliflo and Intellipro pumps as the minimum standard on every project we build, and have been for years. The amazing thing is that we don't just spec these pumps for any one reason. It is
true that some reasons are more compelling or have more significance, but the
reality is, using this pump creates the most efficient, long lasting pool
plumbing system and the easiest filtered and chemically balanced pool; and that
is just the start.



I intend to try to keep this information timely, to the point, and also keep it in layman’s terms in order to help educate the consumer. The main reason; it is my experience that it is more often the
consumer pushing the industry by asking
questions. Unfortunately our industry as
a whole invests little in education and training, and likes to “do it like it
has always been done.” The problem is
that it was very rarely being done correctly and Pentair’s advancements in
technology have changed everything.



Let me list the many reasons and benefits of using this incredible pumping technology, in order from most to least important. (in my humble opinion)



Reason 1: Energy Efficiency


I am going to attack the energy efficiency item from multiple directions. First, because of the electric motor technology used in designing this pump (Permanent Magnet Sychronous Motor or PMSM) it is 30% more efficient than
any other pump on the market at any given speed or horse power. In general a typical induction motor is around 20-30 % efficient. An “energy efficient” motor (with a capacitor)
is around 40-65% efficient. A permanent
magnet synchronous motor (PMSM) is around 90% efficient.



For those of you who need to dig deeper and understand why, go here and it will explain exactly how this motor operates so much more efficiently. http://technicalpoolrepair.blogspot.com/2010/01/pool-motor-efficien...



So if we replace an existing pump on any pool with this pump, set it to the same HP and same schedule we will save at least 30%. Awesome -- but just the beginning. The real savings comes with the true variable speed capacity. There has rarely ever
been a pool built that did not have an oversized pump. -Why you ask, because we
can always close a valve or divert the excess water in motion back to the pool,
but the only way to make sure you had enough water in motion was to install a
pump larger than you might need just in case. With this pump we can actually dial in the
speed exactly, giving us just the amount of volume and pressure to meet our
needs, without wasting any excess energy.
It still gets much better! The
enemy of energy efficiency when pumping water is velocity within the pipe. Velocity Kills! We know that in order to operate some
cleaning systems, we need the water to move pretty swiftly. However we only need the higher velocity for
a few hours at most. But yet we need to
run the pump for 3-4-5 more hours in order to get the overall pool water
turnover we are looking for and we do that at the same high velocity if we are using a standard pump. Solution; run the Intelliflo pump at a
dramatically lower pump speed (lowering velocity) for a longer time. Seems like if we are moving the same amount
of water it would use the same energy right?
NOPE. The friction reduction by
slowing down the velocity is dramatic, and decreases the amount of energy
required. The simple math is this: if
you cut the speed in half(also decreases volume by 1/2), you cut the power used
by 1/8. Since you now need to run the
pump twice as long to move the same amount of water, you end up using ¼ the
power. Cut speed by ¼, use 1/12 the energy. It is that simple. If we move the water slow enough, we can
almost negate the friction during filtering the water.

Reason 2: Water Quality


One of the major problems in pool water quality is a lack of uniform temperature and chemicals, caused by stagnant water. Most pools run roughly 6 hrs a day and sit for the remaining 18 hours. This causes
the water to separate into multiple temperate levels depending on depth and sun
exposure. This causes chemicals like
chlorine to detent off of the surface of the warmer water, and is often the
cause of algae growth in shallows and benches.
Solution, run the filtering cycle throughout the entire day, possibly
even 24 hrs a day. The Pentair
Intelliflo pump allows us to adjust the speed to accomplish the correct
turnover at the slowest speed, which in return is the most energy efficient,
and keeps the pool water consistent throughout the depth and location.


Reason 3: System Performance and Longevity


The Pentair Intellifo pump system also has a slow start and stop function. The means that the pump gradually speeds up and slows down between speed changes and start and stop
functions. You will no longer have any
water hammer or energy spikes within the system. This is a huge longevity issue with the
plumbing fittings, pump seals, and o-rings and filter elements


Newer filter types operate more efficient and filter water better at lower pressures and velocities. So not only are we saving energy at a slower speed, we are filtering
water more effectively.


Every other pump system typically forces us control the flow in the most ineffective way. I like to equate this to driving a car. A normal
pool pump runs like putting the car in drive and putting the accelerator on the
floor the entire time. However when you
need less water, you simply ride the breaks in order to slow the flow, so you
are causing undue pressure and wear on the system in order to control
flow. The Intelliflo Pump lets you lift
off the accelerator and slow the motor down to the needed speed.



Reason 4: Being Truly Green


One can already argue that saving energy is green. That is only the beginning. By using an intellflow pump, we are creating a more sustainable overall hydraulic system, meaning we will use less energy to create new parts and new trips out to work on the system over the systems
lifetime. We also have the ability to
control the pump speeds with automation, add in some automated valves, now we can operate an infinite number of
systems, jets, water features, solar heaters, cleaners etc. with one single pump. How much energy do you think it takes to
create 2 additional pumps, resources needed in raw materials, and the fuel and
energy used to ship that product across the earth. Is Intellifo green? YOU BET, the GREENEST!



If you don’t have an Pentair Intellifo or Intellipro pump, it is time to make the change. If you ware about to purchase a new pool, make sure you insist on the most effective
pool pump period. Pentair Intelliflo!
