CDWdrives delivers engineered solutions and repair services that protect critical equipment, prevent unplanned downtime, and maximize long-term reliability for water treatment facilities.
The sections below demonstrate how our approach extends equipment life and lowers operating costs.
Samiflex couplings provide a durable, maintenance-free solution for water treatment applications where shock, vibration, and misalignment can lead to wear and unplanned downtime. Their design helps protect connected equipment while supporting reliable torque transmission.
Key Advantages
Removable insert without moving either driving or driven equipment
Faster insert changeout than standard coupling designs
No lubrication or maintenance required over the life of the insert
Hubs can be rotated independently during motor testing
No metal-to-metal contact
Compact coupling that provides high torque capacity
Vertical operation possible with standard coupling
Elastomeric Inserts
Standard inserts handle a broad temperature range from -40 to 80°C (-40 to 180°F)
High-temperature inserts are available up to 150°C (300°F)
Resistant to chemical attack
High performance inserts enable torque ratings to be increased by 40%
Applications
Pumps, raw water, high lift, sludge transfer, vertical turbine, chemical dosing, aeration blowers, fans, mixers and agitators, conveyors, and dewatering drives.
Samiflex Coupling
Samiflex Inserts
The CDWdrives Difference
Properly selected Samiflex couplings absorb the shock, vibration, and misalignment that wear out connected equipment—helping water treatment facilities run longer between service intervals.
CDWdrives provides torque limiter solutions for water treatment applications where overload protection is essential to equipment reliability and long-term performance. These engineered solutions help protect connected components and reduce the risk of costly failures.
Key Advantages
Reliable torque overload protection
Immediate and complete disengagement
Precise and consistent torque settings
Quick and easy torque adjustment
Rugged stainless steel construction with added sealing
Optional switch plate and extension hub
Wear- and maintenance-free operation
Applications
Clarifier drives and other critical water treatment systems operating in corrosive, high-moisture environments.
Torque Limiter
The CDWdrives Difference
A correctly sized torque limiter stops an overload before it reaches your gearbox or drive—turning a catastrophic failure into a quick reset.
Our service technicians, backed by our engineering team, quickly identify the root cause of equipment failure and deliver the most effective repair solution to restore performance and extend asset life. Whether the need is a standard rebuild, a retrofit, or a fully custom-engineered solution, we provide reliable results, minimize downtime, and maximize long-term value.
Our repair and rebuild services include replacing damaged components such as broken gears, replacing all bearings and seals, restoring shaft surfaces to like-new condition, and supplying new lubricant.
If our inspection finds that your gearbox or speed reducer is obsolete, unavailable, or impractical to replace, we can provide a cost-effective engineered solution. We reverse engineer units and components and have them custom-built as drop-in replacements that fit your application precisely—reducing costly downtime and getting your operation running again quickly.
Key Advantages
Fast problem identification through disassembly, inspection, and testing to determine the root cause of failure
Rapid sourcing of replacement parts through our global manufacturer network to help return equipment to service faster
Repair, rebuild, and reverse engineering capabilities for obsolete or hard-to-source gearbox components
Engineer-backed solutions for refurbishment, retrofit, reverse engineering and custom replacement designs
Accurate quoting and realistic repair schedules so your team can plan maintenance with confidence
Support for multiple gearbox brands and sizes used across water and wastewater treatment equipment
High-quality parts and workmanship backed by a one-year warranty on parts and services
Applications
Gearboxes and speed reducers used in water and wastewater treatment equipment, including aerators, traveling screens, drum screens, clarifier drives, scum collectors, conveyors, mixers, and other critical rotating equipment. Designed to support reliable operation in wet, corrosive, and continuous-duty environments.
