In applications where there is a need to increase the water pressure, a booster pump might prove to be extremely useful. The required pressure is created by introducing a certain fluid into the pumping chamber. The pump will then maintain a particular vacuum level to make sure this fluid is drawn into an inlet without any external assistance.
Booster pumps are best used in applications and water systems where the contamination level is very low. Apart from a variety of municipal, military, and commercial applications, these pumps are also used in a range of industries such as aerospace, food processing, and mining.
You can use booster pumps to transport various types of media. There are pumps that make use of acidic, abrasive, combustible, hazardous, or corrosive material to increase the system pressure. The others use salt water, wastewater, sludge, ash, food processing wastes, and even sewage. Any type of liquid, liquid metal, and even liquids with solids or slurry can be used to enhance the pressure of the system. The other media that can be used include diesel fuel, gasoline, oil, chemicals, coolants, and lubricants.
Booster pumps are generally manufactured using aluminum, bronze, cast iron, brass, stainless steel, or even plastic. For power source you can use AC or DC voltage, gasoline, natural gas, diesel fuel, steam or water, solar power, and pneumatic or hydraulic systems.
There is usually a pump stator or a rotor assembly that would be mounted onto the booster pump, either horizontally or vertically, according to the orientation of the media. In case of close-coupled pumps the pump end will be mounted on to the motor shaft. On the other hand, a bearing frame would be used by a frame mounted pump to mount the pump end on to the motor.
There are a number of optional features that booster pumps include. There are those that come with thermal overload protection. And then there are a few that are rated to run continuously. You can find self-priming booster pumps that can operate for an extended period of time without any pumped fluid or external lubrication.
You can buy a single stage pump or a multi-stage pump depending on your application. There are also booster pumps such as explosion-proof pumps, hygienic pumps, corrosion-resistant pumps, non-clog pumps, wash-down duty pumps and sanitary pumps that are designed to function in certain special environments.
Whichever water booster pump you may decide to buy, you will have to make sure it meets the guidelines for the application that you would be using it for. Don’t forget to check out the ratings.
