A Booster Pump is a device that raises the pressure of a liquid. They may be used with liquids or gases, although the specifics of construction will differ depending on the fluid.
A gas booster is similar to a gas compressor, but it is a simpler device with just one step of compression that is used to raise the pressure of a gas that is already above ambient pressure. Boosters with two stages are also available. Boosters are used for a variety of purposes, including boosting gas pressure, Conveying high-pressure gas, Charging gas cylinders, and Scavenging.
Simple electrically powered centrifugal pumps with a non-return valve are commonly used as booster pumps for domestic water pressure. They might be constant speed pumps, Which turn on when pressure falls below the low set-point and turn off when pressure rises over the high set-point, or variable speed pumps, Which are adjusted to keep the output pressure constant.
Constant-speed pumps are started by a usually closed low-pressure switch and run until the pressure rises enough to open the high-pressure switch. They’ll cycle anytime there’s enough water to decrease the pressure below the low set point. Cycling will be reduced by using an accumulator in the upstream pipeline.
Pressure feedback is used by variable speed pumps to manage motor speed and maintain a consistent discharge pressure. Most applications employ an inverter to adjust motor speed and run on AC mains power. The reverse osmosis booster pump’s job is to raise the water pressure entering the RO unit.
The process of reverse osmosis is driven by pressure. Small domestic RO systems may theoretically work at extremely low pressures—down to 35 psi, according to some membrane manufacturers—but the truth is that if the pressure is below 45 psi, you won’t receive much water and the product water quality will be reduced.
The unit produces more rejected water, less drinking water, fills the storage tank more slowly, and produces worse quality water when the intake pressure is low. RO units work well with 60 psi city water pressure, but they perform much better with a small pump to increase the pressure to 80 psi or more.
When the typical water pressure feeding a RO system has to be raised or boosted, a RO booster pump is employed. The centering pressure of the feed water determines the effectiveness of a RO booster pump. In order for a reverse osmosis system to work correctly, it must be fed at least 50 psi. The system will generate less water of inferior quality if the water pressure is less than 50 psi. The Advantages of a RO Booster Pump
- More efficient RO system
- Better water quality
- Less water waste
