What is the method of selection of a booster pump for RO plant?
Booster pumps are devices that raise the pressure of a fluid flow system that already exists. They're made to assist pumping systems in achieving higher flow rates and overcoming high system heads. Booster pumps are often used in water systems or applications with low waste pollution. They are utilized in a variety of industries, including aerospace, mining, and food processing, and have a variety of commercial, municipal, and military uses.
Functions of a Booster Pump
Booster pum?ps can be built with a variety of functions in mind:
1: Adjustable or variable speed pumps: These have variable-speed drive (VSD) or adjustable-speed drive (ASD) equipment’s that allow the pump to be adjusted and operated at numerous rates. This is critical for procedures that require a pump or fan to modify its flow during operation owing to specific operating conditions or to save energy.
2: Continuous duty pumps:Pumps that are designed to run and operate continuously without causing undue wear on the pump are known as continuous duty pumps.
3: Multi-stage pumps: These transport compressed fluid from an initial stage to subsequent chambers or stages of pressurization, allowing for higher pressure levels than single-stage pumping. Single-stage and multi-stage systems are commonly used.
4: Self-priming pumps: These generate and maintain enough vacuum to draw fluid into an intake without the need for external help.
How to select the best pump for your RO plant?
The follo?wing steps should be taken to ensure that the correct pump is selected for each process in a water treatment plant:
1. Set the design criteria first. Calculate the maximum, average, and minimum flows, as well as the static heads, suction, and discharge piping configurations.
2. Create a system head curve.
3. Determine the type of pump.
4. Calculate the pump's specific speed in relation to the impeller's properties.
5. Determine the pump's maximum speed.
6. Pick a pump curve.
7. Determine whether a variable-speed pump is needed.
8. To create a system and pump curve chart, superimpose the plot pump curve over the system head curve.
9. Double-check the following details.
Pump manufacturer selection, design point and range of operation, MCF, POR, and AOR, NPSHR versus NPSHA Pump configuration dimensions, maximum operating speed, minimum operating speed, non-overloading HP and motor HP.
10. Determine the materials used in the construction of the pump, including the impeller, casing, shaft, shaft sleeve, ear rings, seal type, and fasteners.
Pump selection process is complete now.
Although RO pumps account for a tiny portion of the total system cost, they must be carefully chosen to avoid inefficient operation, downtime, or lower productivity and return on investment. Because of the corrosive atmosphere and high-demanding process conditions, selecting the right pump for seawater desalination is very critical. In most RO applications, positive displacement plunger pumps or centrifugal pumps are used. Booster pumps, which have a considerably smaller market, can be employed when the typical system pressure is low but needs to be raised.
