VFDs & VFD Control Systems

Smarter Pump Control, Lower Energy Costs

Mercer Controls designs and installs Variable Frequency Drive (VFD) solutions that allow pumps to operate efficiently by matching speed to actual system demand. By replacing traditional on/off pump control with VFD-based control, municipalities can significantly reduce energy consumption while improving system performance.

VFDs are one of the most effective ways to lower operating costs in water and wastewater systems.

Flexible VFD Solutions

We provide VFD solutions to fit any application, including:

• Standalone VFD installation
• Replacement of failed or obsolete VFDs
• Custom VFD control panels for pump stations and plants
• Integration of VFDs into existing control systems
• New installations and system upgrades

Whether you need a single drive replaced or a fully integrated VFD control panel, Mercer Controls can deliver the right solution.

Proven Energy Savings

When properly applied, VFDs allow pumps to run only as fast as needed, reducing wasted energy and mechanical stress. In many applications, converting from standard on/off control to VFD operation can reduce energy costs by 30–40%.

These savings help cities and utilities lower operating expenses and reinvest resources into infrastructure and community priorities.

Built for Reliability & Integration

Mercer Controls selects high-quality VFDs and designs control systems that protect motors, reduce wear, and operate reliably in municipal environments. VFD installations are fully integrated with controls, instrumentation, and monitoring systems to ensure safe, stable operation.
