Drive Replacement and Retrofits
Enhancing Performance and Extending Equipment Lifespan

Efficiency with Flexibility and Fast Turnaround
With decades of experience in the industry, WesTech has improved plant operations by completing retrofits and replacements in multiple processes and allowing the plant to stay in peak operating condition.
Whether you’re a power plant operator or a municipal wastewater plant supervisor, a replacement, retrofit, or even upgrade will improve your plant’s efficiency, meet regulations, and increase capacity.
Drive Replacements
With superior performance and design flexibility, WesTech’s drive units are well-respected in the industry. Our drive units are made from fabricated steel and can be easily customized to any clarifier or thickener, including other manufacturers’ products.
While replacement and wear parts are available for all equipment lines, some of the most requested parts are drive units. The maintenance headaches associated with rebuilding an existing drive are avoided with a drive retrofit or replacement. WesTech can offer a quick turnaround time on the most common retrofits.
These replacement drives offer:
- The same efficient components and quality manufacturing as WesTech standard drives
- Long equipment life
- Less maintenance requirements
- Extended warranty
Increased Capacity with Retrofits and Upgrades
Sustainable plant operations demand continuous optimization, including strategic retrofits and upgrades, to improve processes and equipment. Whether retrofitting or upgrading our own equipment or that of a competitor, we can boost reliability and functionality, while saving you money and time. Our in-house design team streamlines the retrofit process, eliminating the need for outside contractors and engineers.
By increasing throughput and reducing operating costs, upgrades can not only enhance plant capacity but also maximize savings by reusing existing equipment.
WesTech industry-leading retrofit equipment will:
- Restore performance strength to units that have worn out
- Extend equipment service for years, including:
- Water and wastewater plants
- Package plants
- Filters
- Media
- Drives
When an operating plant requires improvements and upgrades beyond equipment replacement, WesTech is your partner and can help assess the enhancements needed.
Equipment upgrades will:
- Increase Capacity: By providing increased throughput and reduced operating costs, upgrades can significantly increase plant capacity and save money by reusing existing equipment.
- Eliminate Bottlenecks: Investment in an equipment upgrade can keep bottlenecks from reducing system capacity when an underperforming part of the process limits throughput.
- Reduce Maintenance Costs: WesTech can help assess whether a replacement or upgrade can meet a water or wastewater plant’s goals to improve maintenance spending.
Case Study

Drive Retrofit Without Full Bridge Removal
After evaluating a 25-year-old drive at a paper mill, WesTech recommended a unit replacement due to excessive wear and high downtime costs from frequent repairs. Using 3D modeling, we avoided removing the clarifier bridge, saving time and money. The new, efficient drive was installed in six days, cutting downtime by a week and securing a contract for replacing a second drive at the mill.
