Reverse Osmosis System Applications for Our Pumps
Great tasting, clean drinking water is a necessity for restaurants, coffeehouses and homes. Reverse osmosis systems filter impurities and chemicals to produce a more palatable water. Mag drive pumps are needed to pressurize the system in order to help remove the various chemicals and impurities.
March Pump Solutions
March pumps have the design and durability for your reverse osmosis system. A typical pump used is a TE-5C-MD, capable of generating a maximum flow of 17 gallons per minute at 4 feet, with a maximum head of 29 feet. The maximum internal pressure the pump can tolerate is 50 psi and can tolerate a maximum liquid temperature of 190 Fahrenheit. Our components can also be used for chemical transfer, small scrubbers and refrigerators.
How Reverse Osmosis Pumps Work
Osmosis moves a solvent, such as water, through a membrane toward a more concentrated solution in an effort to dilute the concentration. Reverse osmosis does the opposite, moving the water out of the concentrated solution, possibly waste water, through the membrane to produce pure water. The system can be made to work with many different solvents, but it is used often to purify water.
Unfortunately, the natural movement is toward the more concentrated waste water, so to produce pure water pressure is required. A reverse osmosis pump moves water through the membrane to produce pure water.
How Much Pressure is Required for a Reverse Osmosis System?
A pressure differential is required to move the water through the membrane. The pressure on the incoming water must be higher to force the water through the membrane and purify the water. The ideal pressure for a RO system is 60 psi. If the pressure falls below 40 psi, a booster pump is recommended. Our mag drive pump is an excellent choice.
Running the system at a low psi can cause problems. The membrane may become fouled and become less effective. The production rate drops and other problems can occur.
Advantages of Mag Drive Pumps for RO Systems
A March magnetic drive pump eliminates the problems and costs associated with mechanical seals while increasing the water supply pressure to the RO system. The design of a March magnetic pump has advantages in a RO system:
Reduced risk of fluid or vapor leaks
Reduced risk of exposure to contaminated, hazardous, corrosive, toxic, flammable, or explosive fluids
Reduced waste of water or other valuable liquids
A constant pressure supply line reduces RO chatter
March magnetic drive pumps are reliable
Magnetic drive pumps require very little maintenance
March mag drive pumps are easy to couple and need no alignment of the pump or motor
Because of these advantages, mag pumps are superior to most delivery pumps or demand pumps for use in a RO system.
If you need a delivery pump, demand pump, or booster pump for your home or commercial reverse osmosis system, consider a March magnetic drive pump. These pumps are designed to perform well for many years with little to no maintenance.
