General Information

Use in process engineering and technology, chemical industry, transport of chemicals, desulfurization and denitrification systems, sewage purification, water purification, environmental technology, hygiene technology and sanitary engineering.

In the above mentioned areas they serve as safety and cleaning devices on containers, piping and pump systems.

THOMAFLUID^®-strainers made of PVC-U, PP or PVDF are indispensable wherever the transport of soiled media is required. They reliably prevent operating troubles by catching contaminations from the medium. The strainers serve for plant protection ensuring avoidance of dirt deposits. They are metal-free, thus preventing media oxidation. The use of high-quality materials in housing and screen ensures break resistance and corrosion resistance. The disassembly without using tools allows a quick and easy cleaning. The strainers are of simple construction, thus maintenance-free and feature a long service life.

Strainers protect sensitive components used in plants and sanitary engineering against contamination. The dirt is filtered out of the medium by a filter element (screen tube) with accordingly defined filtration rating.

Leak-free cleaning of liquid and gaseous media.

All medium-contacting parts are made of plastics with high resistance to chemicals. They are particularly suitable for applications where aggressive media are to be conveyed and blocked.

The connection of PVC fittings to piping is effected at the first application by adhesive bonding of the connections with the pipe, in the case of PP and PVDF fittings connection and pipe are welded together. Once the fittings are fixed to pipes, they can be easily removed from the pipe by disconnecting the screw joint.

PVC-U (rigid polyvinyl chloride): Resistant to most alkalis, acids, salt solutions and water-miscible organic compounds. Not resistant to aromatic and chlorinated hydrocarbons.

Polybutene: Resistant to aqueous solutions of acids, salts, alkalis and a lot of organic solvents. Not resistant to concentrated, oxidizing acids.

PVDF (polyvinylidene fluoride): Resistant to acids, salt solutions, aliphatic and aromatic (chlorinated) hydrocarbons, halogenes and alkohols, but only of limited resistance to ketones, esters, ethers, and not usable for organic bases and alkalis.

PTFE (polytetrafluoroethylene): PTFE is resistant to most chemicals.

FPM (fluorinated rubber): High chemical resistance to all kinds of solvents. Not suitable for hot steam, organic acids and strong bases.

PP (polypropylene): Resistant to aqueous solutions of acids, salts, alkalis and a lot of organic solvents. Not resistant to concentrated, oxidizing acids.

FEP (fluoroethylene-propylene): FEP is resistant to most chemicals.

Material of housing: PVC-U, PP, PVDF (injection-molded)

Temperature range:

PVC-U up to +60 °C; Polybuton up to +90 °C; PVDF up to +100 °C; PTFE up to +250 °C; FPM up to +150 °C; PP up to +90 °C; FEP up to +150 °C

Connection: The screw joints on both sides contain O-seals, insert parts and cap nuts. The fittings are supplied as complete unit with the screw joint. They are fitted with end fittings for fastening to pipes.
