Applied Motor Controls for

Water & Wastewater

Ensuring Reliable Water Management

In water and wastewater operations, reliable motor-driven equipment is essential for continuous, safe, and efficient processing. AC induction motors power pumps, aerators, milliscreens, separators, and blowers, keeping water flowing and treatment processes running smoothly. With our expertise in motor control and automation, we help operators optimize performance, reduce downtime, and maintain safe, dependable operation across municipal and industrial water systems.

Frequently Asked Questions

What equipment benefits from Benshaw VFDs and soft starters in water and wastewater operations?

Benshaw drives and soft starters are commonly used on water pumps, wastewater pumps, aerators, mixers, and blowers. They provide precise motor control, improve system efficiency, and reduce mechanical stress on critical pumping infrastructure.
How do soft starters improve water and wastewater operations? Soft starters provide gentle, torque-controlled acceleration of pumps, reducing surge loads on electrical supplies and mechanical stresses caused by rapid pressure changes. Soft stop functionality also prevents water hammer, protecting pumps, pipes, valves, and headworks while extending equipment life.
Can Benshaw soft starters save energy in water and wastewater facilities? Yes. By reducing pump cycling caused by pressure fluctuations, soft starters minimize energy usage and operational costs, while ensuring more consistent water delivery and wastewater processing.
How do VFDs support system control and process optimization? VFDs allow pumps and fans to operate only at the required speed, improving system efficiency, reducing energy use, and enabling more intelligent control over the entire water or wastewater network.
Can soft starters reduce water hammer in pumping systems? Yes. By controlling the acceleration and deceleration of pumps, soft starters can minimize pressure surges and water hammer, protecting piping and associated equipment.
Can soft starters reduce maintenance and protect equipment investments? Yes. By minimizing mechanical shock on pumps, pipes, valves, and other components, soft starters reduce wear, prevent downtime, and extend the life of critical infrastructure.
Can soft starters improve pumping efficiency and reduce valve wear? Yes. Gentle acceleration and deceleration reduce valve wear and help maintain optimum water pumping efficiency across the system.
How do VFDs and soft starters support long-term operational and financial benefits?

By reducing mechanical stress, improving energy efficiency, and optimizing system control, Benshaw drives and soft starters protect equipment investments, maximize productivity, and provide intelligent operation of water and wastewater systems.
