Product Description

Constant pressure systems are changing the standard for private well systems all over the country. A private water well is one of the best sources of water for your home, but just as in municipal water systems, water pressure may sometimes be insufficient for the changing demands of the home. If you have a problem with water pressure in your home, you may have noticed that your washing machine fills more slowly when your dishwasher is running, or that your shower sputters when your sprinkler turns on. You don't like it, but you live with it.
Now you have a choice!
With a constant pressure system, you don't have to schedule your day around your water usage.  SubDrive and MonoDrive constant pressure controllers vastly improve your home water system. Using variable speed technology, SubDrive and MonoDrive continuously monitor water demand and adjust the speed of your pump to provide the water you need without pressure fluctuations. Available in a wide variety of ratings, these systems also provide:
 Smooth, quiet operation
 Choice of pressure settings
 Built-in pumping system protection

The advantages of constant pressure systems:
Support high volume needs
Variable speed monitors demand
Mechanical stress on the pump is reduced
Constant pressure regardless of fluctuation
Saves energy consumption and costs
Save space with a smaller pressure tank as needed
Can easily be expanded for future needs

The Variable Frequency and Speed Regulation Constant Pressure Water Supply System Based on PLC and Fuzzy Control
 
For solving the problem of poor quality and waste of electric energy coursed by water supply mode of a high water tower and a direct water pump, introduce a constant pressure supply water system, which adopts embedded fuzzy control technology, using PLC and frequency convener as its core. When the system runs, water pressure of the pipe is inputted into the PLC from terminal X0 through pressure transmitter. Comparing the value of measured pressure with its set value, PLC controls the work frequency of the frequency converter by the output signal on fuzzy calculation in order to control rotation speed of water pump and adjust water pressure of the pipe. The real time control performance to the water pressure of water supply system designed in this paper was proved to be all-right according to the experimentation validated. The hard ware module is steady-going and reliable, and the fuzzy controller is proper and valid and can guarantee the better stability of water pressure.
 
 

How Constant Water Pressure Systems Work?
 
Let's say that the system installed is a C.P 75 Sub- Drive 1-1/2 hp (20 gpm ) with a set pressure of 65 psi, as you open up the kitchen faucet which takes approximately 3 gpm the pressure transducer reads the pressure drop and sends the signal to the drive which then ramps up the pump to maybe 1800 rpms, because the demand is only 3 gpm the pump doesn't need to spin any faster to maintain the 65 psi set pressure, as you open up additional faucets creating more of a demand the rpms of the motor speed up to meet the demand and maintain the 65 psi set pressure. As the demand subsides the rpms slow down until the pump go's into sleep mode when no water is being used.
The advantages are the electric that runs the pump is more economical in that it's a 3 phase motor, no pressure fluctuations when water is being used at different locations in the house, the entire system is wall mounted with a small pressure tank which free's up floor space. Constant water pressure systems come in a variety of models ranging from 20 gpm through 90 gpm.
