A booster pump is used to increase low system pressure. Aside from it being easy to install and use, booster pumps are commonly used in water systems where contamination is low and can be applied to commercial, industrial, military and residential purposes.
How a booster pump works
The pump involves priming, in which the fluid is introduced into the chamber to allow the needed pressure differential for pumping at a given rate. A self-priming booster pump enables and ensures adequate vacuum level to accumulate fluid into an orifice by itself.
Depending on its use, a booster pump can transport various types of media. Among the materials used to raise system pressure are the following:
- Gasoline, diesel fuel and other lubricants
- Other chemicals and coolants
Booster pumps can be made of stainless steel, aluminum, plastic, bronze, cast iron or brass. It operates on the following power sources:
- AC/DC voltage
- Hydraulic systems
- Gasoline/diesel fuel
- Solar power
Structure and features of a booster pump
Booster pumps come with rotor assembly that is either in a vertical or horizontal position depending on the media’s orientation. The pump end, which is found on the motor shaft, is mounted by close-coupled pumps while the one that is on a bearing frame attached to the motor is mounted by frame-mounted pumps.
A booster pump may come with the following features:
- Multi-stage pump function. Pump draws compressed fluid from the first phase to consequent pressurization stages or chambers to allow higher pressure levels.
- Pressure gauge. This feature is typically present in both single and multi-stage booster pumps.
- Self-priming option. Pump operates without external lubrication for a given period of time.
- Thermal overload protection. Pump runs continuously at a given rate.
Different type of booster pumps
There are some booster pumps that are created for special applications.
- Wash down duty pumps. These booster pumps work better in wet and humid conditions such as in dairy plants and other food processing industries.
- Sanitary pumps. This type of booster pump satisfies stringent sanitary guidelines with different classifications, among which include 3A, FDA and USDA.
- Non-clog pumps. These pumps are designed to pump slurry materials that may clog other kinds of booster pumps.
- Hygienic pumps. They are fully sealed to get rid of contamination or leakage. These pumps are made of stainless steel, such that it can resist corrosion.
- Explosion-proof pumps. This type of booster pump shields parts that may cause ignition of the transfer media and/or its surrounding atmosphere.
