St. Joseph, Missouri

Over three decades, all VFDs were replaced multiple times at a cost of several million dollars. Maintenance and replacement costs on the VFDs were high. Long-term reliability and factory support have been inferior. All original eddy-current drives, installed in the 1960s, continued as operational. Annual maintenance costs for the eddy-current drives were very low. The city of St. Joseph replaced VFDs with Dynamatic® eddy-current drives, and all new variable speed applications for the ruggedness, longevity and cost-savings of the Dynamatic product.

Lemay Pumping Station

When a cost/performance evaluation was conducted across the municipality’s 200HP and larger electromagnetic pump-drive systems, management determined that these applications would be best served by upgrading all existing Dynamatic® drives from analog based controls to new digital controls.

Columbus, Ohio Case Study

After interviewing Dynamatic and several VFD/Motor vendors, the City and Engineer concluded that Variable Frequency Drive’s, cost, space considerations and cooling requirements were not favorable for the project. Their best option was to replace the Eddy Current Drives in kind with new Dynamatic SPMV-8260 units, they are rated at 1250 HP, 514 RPM, 4160 volts.

A Low Cost Approach To Green Energy

The benefits of variable speed pumping have long been recognized, including reduced power cost, reduced mechanical wear and process optimization. In today’s economy and environmental awareness, a significant reduction of a company’s carbon footprint can now be added to the list of benefits. Electromagnetic drives can often prove to be the best path to achieve these results, and can be shown to pay for themselves over a long period of service.
