Variable frequency drive pump: efficiency and savings 

A variable frequency drive water pump is a type of pump that uses a variable frequency drive to control the operating speed of the motor. This type of pump allows the amount of water being pumped to be adjusted, which in turn can help save energy and improve overall efficiency.

The variable frequency drive works by changing the frequency of the electrical current that powers the pump motor. By reducing the frequency, the motor speed is reduced, resulting in slower water flow. Increasing the frequency increases the motor speed, resulting in faster water flow. In this way, the amount of water pumped can be adjusted to meet the specific needs of each application.

In general, they are an efficient and versatile choice for many pumping applications, such as irrigation systems, HVAC systems, water supply, among others.

NOXPLUS variable speed pump: energy savings

Energy Efficiency

By allowing control of the motor operating speed, variable speed drive water pumps can be set to operate at only the amount of power needed at any given time. This can result in a significant reduction in energy consumption and energy costs.

Better flow control

Variable frequency drive water pumps allow the amount of water being pumped to be adjusted to meet the specific needs of each application. This can result in better control of water flow, which can be especially useful in irrigation systems and swimming pool filtration.

Longer service life

By allowing the motor operating speed to be adjusted, variable frequency drive water pumps can reduce the amount of wear and stress on the motor and other pump components. This can result in longer pump life.

Less noise

Water pumps with variable frequency drives can run at lower speeds than conventional pumps, which can result in quieter operation.
