Water and wastewater treatment plants face constant pressure: aging infrastructure, rising energy costs, and equipment that must run reliably around the clock. Pumps, agitators, and rotating equipment fail under abrasive slurries, corrosive chemicals, and continuous load — and every unplanned shutdown has a direct cost.
The challenge is systemic. From the lift station to the effluent discharge, every stage of the treatment process depends on equipment that performs consistently — under difficult conditions, often unmanned. Managing maintenance costs while meeting increasingly strict environmental regulations demands solutions that address the entire system, not just individual components.
Chesterton provides sealing, coating, lubrication, and condition monitoring solutions across the entire treatment process — proven in wastewater and potable water facilities worldwide.
Why plants choose Chesterton:
- Extended seal and pump life in abrasive and corrosive media
- Reduced flush water consumption with advanced sealing technology
- Corrosion and wear protection for metal and concrete surfaces
- Condition monitoring to detect failures before they cause downtime
- Products certified for potable water contact (NSF 61, WRAS, ACS)
- Local service specialists with documented application experience
Our Solutions for Water & Wastewater
Mechanical Seals
Chesterton mechanical seals and packings reduce maintenance costs and extend uptime in drinking water and wastewater applications. Many products are designed to extend the life of worn equipment and meet international drinking water requirements.
Equipment Monitoring
The Chesterton Connect system is a condition-based maintenance tool designed to monitor critical equipment. Avoid unplanned downtime, reduce maintenance costs, and protect your assets by remotely monitoring equipment health around the clock.
Industrial Coatings
Aging infrastructure is the biggest challenge in the water and wastewater industry. Chesterton coatings enable the repair of older metal and concrete equipment, minimizing downtime and costs. Applied to new and older plants, they help maximize energy efficiency while meeting international drinking water requirements.
Industrial Lubricants
Chesterton industrial lubricants and greases protect bearings in harsh conditions including stress, vibration, water, and corrosion. Quiet Bearing Technology (QBT) combines water washout and corrosion resistance with extreme pressure and temperature resistance to increase bearing life and equipment reliability.
Polymer Seals
Chesterton polymer labyrinth seals, lip seals, and throat bushings protect pump bearings and stuffing boxes across water and wastewater treatment applications — from lift station and influent pumps to sludge and thickened sludge duties. They are selected for reliability in continuous service handling media with varying solids content.
Mechanical Packing
Chesterton DualPac 2212 is the primary packing recommendation across water and wastewater treatment applications, covering raw wastewater, grit, primary sludge, and treated water duties. Designed for use with a clean flush arrangement, it reduces leakage and extends service intervals on rotating equipment.
