Water Treatment
Water Treatment
In the demanding environments of the water treatment industry, where equipment is exposed to corrosive chemicals, extreme temperatures, reactive gases, and continuous operation, selecting the right lubricant is critical for system integrity and long-term reliability.
Halocarbon lubricants based on PCTFE (polychlorotrifluoroethylene) chemistry offer unmatched chemical inertness, nonflammability, and thermal stability, making them exceptionally well-suited for applications in water purification, disinfection, and chemical injection systems. Unlike conventional oils and greases, these specialty lubricants resist degradation in contact with chlorine, ozone, acids, and alkaline cleaners, which are very common challenges in modern water treatment operations. Many of these trusted lubricants are listed in the Chlorine Institute Pamphlet 164 as lubricants suitable for chlorine service.
Chemical Injection Systems
Chemical injection systems are critical components in water treatment facilities, responsible for delivering precise amounts of disinfectants like chlorine, sodium hypochlorite, and other oxidizers into water streams. These systems operate in aggressive chemical environments, often at elevated pressures, and rely on tight sealing and mechanical performance across valves, regulators, pumps, and tubing connections.
Traditional lubricants break down quickly under these conditions, leading to corrosion, leaks, and system failures.
Halocarbon products formulated with PCTFE are engineered to withstand these demanding environments, exhibiting excellent lubricity and superior chemical resistance making them uniquely suited in applications involving chlorine (Cl2) and other reactive gasses.

Instrumentation in water treatment
In the water treatment industry, instrumentation plays a mission-critical role in ensuring accurate chemical dosing, system monitoring, pressure regulation, and process automation. Devices such as differential pressure gauges and diaphragm seals are constantly exposed to aggressive chemicals like chlorine, ozone, caustics, and acids for conditions that demand robust, chemically inert fill fluids for both safety and performance.
If the wrong fluid is used it can:
- Cause false readings that lead to dangerous dosing or system mismanagement.
- React with chlorine or acids, generating heat, gas, or corrosive by-products.
- Compromise the sensor diaphragm, leading to rupture or internal leakage.
Halocarbon oils eliminate these risks by offering a stable, inert, non-reactive medium that ensures both measurement accuracy and personnel safety which are key values in any water treatment or environmental control application.

Water treatment Process Equipment
In water treatment facilities, critical process equipment such as mechanical seals, compressor skid bearings, and gear-driven mixers operate under demanding conditions. These machines frequently encounter oxidizing disinfectants (chlorine, ozone, peracetic acid), elevated temperatures, variable pressures, and tight tolerances.
Halocarbon lubricants are PCTFE-based broad viscosity lubricants that are tailored for these rigorous environments, offering operational reliability, safety, and performance longevity.
By integrating Halocarbon oils into process equipment lubrication:
- Equipment and elastomers are less susceptible to corrosion
- Equipment suffers lower down-time
- Operations remain safe and compliant under harsh chemical exposure

Corrosion Prevention
Corrosion prevention is not just a good practice, it’s a mandatory requirement in water treatment: safeguarding public health, protecting infrastructure, and meeting required regulations. Corrosion in pipes, tanks, pumps, or connections can release harmful metals like lead, copper, and iron into drinking water Inherently threatening health. It can also lead to pipe failures, leaks, and system disruptions thus undermining water distribution and treatment operations. Corrosion prevention is a non-negotiable pillar in water treatment. Reduced corrosion means less water loss, energy savings, and reduces equipment down-time, aligning with resilience and sustainability goals.
Halocarbon Lubricants play a vital role in mitigating corrosion within water
treatment systems, especially those handling oxidizers, aggressive chemicals,
and reactive gases. PCTFE oils and greases are inherently chemically inert and
nonreactive, even in the presence of aggressive oxidizers such as chlorine,
ozone, hydrogen peroxide, and other acids affiliated with the water treatment
industry. These lubricants remain stable up to ~200 °C, resisting breakdown
where heat and oxidizers coexist. This unique polymer structure is exceptionally
non-absorbent and moisture-resistant, making it effective in damp or humid
environments typical of water treatment and for added protection, most
halocarbon products are optional with the addition of a formulated rust inhibitor
(+).
