You may have
heard of water pressure booster pumps, but what about VFD water booster
pumps? Do you know what makes them a great feature for commercial or
high-rise buildings? Here’s everything you need to know about the VFD waterpump.
What is a Variable Frequency Drive
(VFD)?
Most water
pressure booster pumps need to be sized to maintain their design pressure. They
experience maximum water flow at the lowest suction pressure. You can use a
pressure control valve to control the system and maintain the desired pressure,
but that’s not an ideal solution as it may cost you more time, money, and effort.
With a
variable frequency drive, you can eliminate the need to have pressure control
valves. This may save energy and eliminate maintenance costs. In fact, the
addition of a VFD can save up to 20% of the overall amount. Also, VFD water
booster pumps are great when it comes to slurry pumping applications and
optimal pumping efficiency.
Why VFD Water Booster Pumps?
By adding a
variable frequency drive to your booster pump, you can change it from one speed
or single flow rate to variable speeds. And you know what? You don’t need a
gearbox or electric motor. VFD pumps have other benefits too, besides
regulating the flow rate.
These pumps can
help you reduce power consumption, minimize the cost of operation, and save
space. In the long run, the addition of a VFD can result in big savings and
reduce the cost of ownership. You can fit it with other programmable control
components to increase the flexibility of water booster pumps.
Top benefits
of using VFD water booster pumps:
1.
Energy Reduction
VFDs are great
when it comes to saving energy. When you use them in combination with
intelligent pump management tools, they increase energy efficiency. However,
VFDs are a double-edged sword because they may cost you the most energy when
used in the wrong way. So make sure you fully understand the need to have a
VFD.
2.
Extended Pump Life
Yes, VFDs
can extend your NJ Water Booster Pump’s life. However, they can also
damage pumps when you lack the tools to know where your pumps are operating on
the tested curves. So make sure to read about the importance of pump testing
and how VFDs fit into the equation.
3.
Easier Pump Selection
VFDs can
simplify the pump selection process. Instead of opting for a pump for peak days
and another one for low flow days, you can have a pump that serves both
purposes. In other words, you can invest in VFD water booster pumps that have
increased operation flexibility.
4.
Alleviate Pressure Transients
When your
water booster pump starts or stops, its velocity changes. Thus, it creates
pressure waves that echo until friction disintegrates them. The magnitude of
these waves can be significant in bigger settings, which can result in water
pressure loss. VFDs can adjust the speed of your pump and slow down the change
of velocity in the pipe system.
5.
Control Full Load Amps
Sometimes,
motors operate very close to the rated Full Load Amps (FLA). In other words, it
runs at design capacity. By pulling additional power, you could overload or
damage the motor. However, VFDs are the solution as they offer a configurable
output current, which keeps the motor amps below the configured point.
6.
Regulate Inrush Currents
A fixed-speed
motor results in a large electrical surge when it starts. The surge appears from
the motor, and its magnitude might be several times the normal full load
current. Therefore, high loads can damage your motor and electrical equipment.
They can also make the sizing of current protection equipment overwhelming. To ramp
up speeds slowly, you will need VFDs. They will help you reduce the start-up
motor load and resultant inrush currents.
7.
Phase Loss Protection
Lastly, VFDs
are able to keep your booster pumping even through a phase loss. Because the DC
signal sent to the motor is removed, the drive can feed it power as long as the
motor isn’t close to full power. You can also configure this feature for better
management.
