Constant Pressure Won't Work and the Earth is Flat
"The earth is flat, if you go too far you will fall off." "A ship made of steel will sink like a stone." "The
automobile will never replace the horse." "Man was not meant to fly."
Where would we be today if people like Columbus, Henry Ford, and the Wright Brothers had believed what
they were told and never tried otherwise? Some of the best ideas we have came from people who were
laughed at, scorned, or even imprisoned for going against the popular belief.
It wasn't long ago that people were saying "an electric motor will never work under water". Even more
recently we were told that "a bladder tank will never replace a standard hydro tank", or that "it simply
would not be wise to hang a submersible pump on plastic pipe". All of these things are now standard in the
industry. Somewhere down the line, someone had to try it anyway, even though they were told it would
not work.
The new "buzz word" in the pump industry is "constant pressure". Many people are starting to see the
benefits of "constant pressure" and want to know the best way to accomplish it. Like the bladder tank and
plastic drop pipe, "Constant pressure" will soon become the standard. The sooner you start on the learning
curve, the easier it is to keep up with technology.
"Constant Pressure Valves" and "Variable Speed Pumps" are the two most common ways of producing
"constant pressure". Several new versions of Variable Speed Pumps are now available. There are a few
minor differences in how they function but they all electronically control the speed of the motor to vary
the pump flow rate.
Several versions of Constant Pressure Valves are also now available. There are small differences in these
valves but, they all simply throttle the flow from a pump to produce variable flow rates using ordinary
constant speed motors.
Many "Experts" continue to argue as to whether "Variable Speed Pumps" or "Constant Pressure Valves" are
the best way to control pumps. Where would we be today if Columbus and the Wright Brothers had listened
to the so called "experts"? The ONLY thing you can be absolutely sure of is that anyone who claims to
know all about it, doesn't.
The best reason to try something new is because the "experts" say it won't work. Testing "Constant
Pressure Valves" and "Variable Speed Pumps" yourself is the only way to find the truth. After a year or
two you will know what doesn't work. After three to five years you will begin to understand what is working
and why.
Don't get caught with 500 or 1,000 of any new product out in the field until it has stood the test of time
and you know you can depend on it. But don't be afraid to try new things. Test new products on your own
house or your brother in laws house. Give a few customers you know a little discount to be a guinea pig for
you. Compare "Constant Pressure Valves" to "Variable Speed Pumps" and any other systems on the market.
We tend to learn more from things that don't work than from things that do work. No news is good news,
so remember that the systems you don't here from are the best ones.
"Constant pressure" will soon be as common as pressure switches and plastic pipe. If you don't get on board
and try new things, your world will always be flat.
